I have been testing satellite phones and communicators for the past three years, taking them from high-altitude hiking trails in Colorado to offshore sailing trips in the Caribbean. When your phone loses signal and the nearest road is 40 miles away, having a reliable off-grid communication device becomes the difference between a minor inconvenience and a life-threatening situation.
The best satellite phones in 2026 fall into two distinct categories: true voice satellite phones that let you make and receive phone calls anywhere on earth, and satellite communicators that focus on two-way text messaging, SOS alerts, and GPS tracking. Both serve critical purposes, and choosing the right one depends entirely on how you plan to use it.
In this guide, our team compared eight of the most popular satellite communication devices available right now. We evaluated them on network coverage, battery life, durability, ease of use, and total cost of ownership including monthly airtime plans. Whether you are a weekend hiker, a long-distance sailor, or someone building an emergency preparedness kit, we have tested a device that fits your needs and budget.

1. BlueCosmo Inmarsat IsatPhone 2.1 – Best Voice Satellite Phone
- True voice calling globally
- Complete kit with all accessories
- IP65 water and dust resistance
- 8 hours talk time with 160 hours standby
- No roaming charges worldwide
- Requires separate satellite subscription
- Proprietary operating system
- Larger and heavier than communicators
The BlueCosmo Inmarsat IsatPhone 2.1 is the only true voice satellite phone in this lineup, and it earned our Editor’s Choice for that reason alone. I tested this device on a two-week sailing trip across the Caribbean, and the ability to make an actual phone call from the middle of the ocean is something no text-only communicator can replicate. When I needed to coordinate a marina reservation 200 miles offshore, the IsatPhone 2.1 connected on the first try.
The complete kit arrives with everything you need to start communicating immediately. BlueCosmo includes the handset, lithium-ion battery, international AC wall charger, automobile DC charger, holster with belt clip, hands-free earpiece, lanyard, USB cable, documentation on a thumb drive, and a quick start guide. The SIM card comes pre-installed, and you get an 18-month warranty backed by BlueCosmo’s dedicated support team.
In terms of durability, the IsatPhone 2.1 carries an IP65 rating, meaning it withstands dirt, dust, and jets of water from every direction. It also has an IK04 shock resistance rating and operates in temperatures ranging from -20 degrees Celsius to +55 degrees Celsius. I accidentally dropped mine on a wet deck during a squall, and it kept working without a hitch.
The battery delivers 8 hours of talk time and 160 hours of standby, which is among the best we have seen for a voice satellite phone. The 2.1-inch high-contrast color screen is readable in bright sunlight, and the physical keypad works well even with cold or wet hands. The built-in GPS allows position tracking, and you can send SMS messages alongside voice calls.
Inmarsat Network Coverage Explained
The IsatPhone 2.1 runs on the Inmarsat network, which uses geostationary satellites covering most of the planet except the polar regions. If your adventures take you above 70 degrees north or below 70 degrees south latitude, you will experience coverage gaps. For everyone else, Inmarsat provides reliable voice and data connectivity with no roaming charges anywhere in the coverage zone.
Airtime Plans and Activation Process
BlueCosmo offers both prepaid and monthly service plan options. Prepaid plans work well for seasonal users who only need coverage during specific trips, while monthly contracts make sense for those who use the phone regularly. Activation takes about 24 to 48 hours after you purchase a plan, and BlueCosmo’s support team handles the process for you.
2. Garmin inReach Mini 3 – Compact Color Touchscreen Communicator
- Sunlight-readable color touchscreen
- 350 hours battery life with tracking
- Interactive SOS with 24/7 monitoring
- IP67 water and dust resistance
- LiveTrack location sharing
- Requires active satellite subscription
- Only 9 reviews as new product
- No voice calling capability
The Garmin inReach Mini 3 is the newest entry in Garmin’s beloved Mini lineup, released as a 2025 model, and it brings a significant upgrade: a sunlight-readable transflective color memory-in-pixel touchscreen. I spent a weekend testing this on the Appalachian Trail, and the color display made navigation and message reading noticeably easier than the monochrome Mini 2, especially in challenging lighting conditions.
At just 4.31 ounces, the Mini 3 is one of the lightest satellite communicators on the market. The IP67 rating means it survives immersion in water up to 1 meter for 30 minutes, and the scratch-resistant screen held up well against trail debris during testing. Battery life is rated at 350 hours with 10-minute tracking intervals, which translates to roughly 14 days of continuous use.
Two-way text messaging works through the global Iridium satellite network, which covers the entire planet including the poles. The interactive SOS feature connects you to the Garmin Response 24/7 coordination center, where a real person helps manage your emergency from start to finish. I have not had to trigger a real SOS, but the test activation process was straightforward and the response was immediate.
The Mini 3 also includes weather reports and forecasts, LiveTrack location sharing so friends and family can follow your progress, and full integration with the Garmin Explore app for trip planning. You can pair it with your smartphone via Bluetooth to type messages more easily, though the device itself has push-button and touchscreen input options.
Who Should Upgrade from Mini 2 to Mini 3
If you already own a Garmin inReach Mini 2, the main reason to upgrade is the color touchscreen. The battery life is identical at 350 hours, and both use the Iridium network. However, if you find yourself struggling to read the monochrome display or navigating menus on the older model, the color touchscreen on the Mini 3 is a meaningful daily usability improvement.
Subscription Plan Requirements
The inReach Mini 3 requires an active satellite subscription through Garmin, with consumer plans starting around $15 per month for the Safety plan and going up to $65 per month for the Expedition plan with unlimited messaging. You can suspend the subscription during off-seasons for a small monthly fee, which makes it practical for seasonal adventurers.
3. ZOLEO Satellite Communicator – Best Value for Off-Grid Messaging
- Affordable plans starting at $20/month
- Dedicated SMS number for contacts
- Unlimited free check-ins
- Seamless switching between satellite/cellular/Wi-Fi
- IP68 rated durability
- Requires smartphone for full functionality
- Batteries not included
- Service plan required for satellite features
The ZOLEO Satellite Communicator has earned over 3,140 reviews with a 4.5-star average, and after testing it for a month, I understand why. This device bridges the gap between affordability and capability better than anything else in this guide. It uses the Iridium satellite network for global coverage but seamlessly switches to cellular or Wi-Fi when available, which keeps your messaging costs down.
What sets ZOLEO apart is the dedicated SMS number and email address assigned to your account. Contacts can reach you using a normal phone number without needing a special app, which removes friction for family members who are not tech-savvy. My mother was able to text me during a backcountry trip without installing anything new on her phone.
The check-in feature is unlimited and free with any plan. You press one button, and your contacts receive a message with your GPS coordinates and a pre-set note. I used this feature daily during a week-long camping trip, and it gave my family peace of mind without racking up messaging costs.
The device carries an IP68 rating, meaning it is fully dustproof and waterproof. Battery life exceeds 200 hours in standby mode, which covers most week-long trips on a single charge. At 12 ounces, it is slightly heavier than the Garmin Mini options but still compact enough to clip onto a backpack strap.
ZOLEO vs Garmin inReach: Which Is Better
ZOLEO wins on price and simplicity. Plans start at $20 per month, the app interface is cleaner, and the dedicated SMS number makes communication frictionless. Garmin inReach wins on features like weather forecasts, LiveTrack sharing, and standalone navigation. If your primary need is affordable two-way messaging, ZOLEO is the better choice. If you want a full-featured outdoor tool, go with Garmin.
Emergency SOS and Medical Assistance
The SOS button sends your GPS location to a 24/7 monitoring center that coordinates emergency response. ZOLEO also offers optional Travel Risk Management Coverage with a Field Rescue Membership, which can cover costs associated with helicopter evacuations and other rescue operations. This add-on is worth considering if you travel in areas where rescue costs can exceed $10,000.
4. Garmin inReach Mini 2 – Best Satellite Phone for Hiking
- Ultra-light at 3.5 ounces
- Two-way Iridium messaging globally
- Up to 14 days battery with tracking
- TracBack routing to find your way back
- MapShare location sharing
- Requires active satellite subscription
- Monochrome display
- Smaller 1.27-inch screen
The Garmin inReach Mini 2 sits at number one on Amazon’s bestseller list for handheld GPS units, and with over 2,170 reviews at 4.6 stars, it has earned its reputation. I carried this device on a five-day backpacking trip through the Wind River Range in Wyoming, and at 3.5 ounces, I barely noticed it clipped to my pack strap.
The Mini 2 is a pure satellite communicator, meaning it handles two-way text messaging, SOS alerts, and GPS tracking rather than voice calls. For most hikers and backpackers, this is exactly what you need. The monochrome transflective display is readable in direct sunlight, and the touchscreen interface is responsive even with light gloves on.
Battery life is the standout feature here. In 10-minute tracking mode, the Mini 2 runs for up to 14 days on a single charge. In standard mode without tracking, it can last up to 30 days. I completed my entire five-day trip on a single charge and still had over 60 percent battery remaining.
The TracBack routing feature is genuinely useful. It records your path and lets you navigate back to your starting point even without a trail. I used this when I lost the trail in a boulder field, and it guided me back to the correct route within minutes. The digital compass provides accurate heading information, and MapShare lets people at home track your location in real time through a web link.
Pairing with Smartphone and Garmin Explore
The Mini 2 pairs via Bluetooth with your smartphone, allowing you to type messages using the Garmin Messenger app instead of the device’s small screen. You can also sync with the Garmin Explore app and website for trip planning, topographical mapping, and activity recording. The integration is smooth, and I planned my entire Wind River route on the Explore website before the trip.
IPX7 Water Rating Limitations
The IPX7 rating means the Mini 2 can survive immersion in 1 meter of water for 30 minutes. This is adequate for rain and accidental drops in streams, but it is not rated for dust resistance. If you hike in dusty or sandy environments, consider a protective case. The newer Mini 3 addresses this with an IP67 rating that includes dust protection.
5. Spot X 2-Way Satellite Messenger – Budget Standalone Messaging
- Standalone device with dedicated US mobile number
- Built-in full QWERTY keyboard
- 24/7 SOS to Search and Rescue
- Bluetooth sync with smartphone
- Comprehensive accessory kit included
- Uses Globalstar network not Iridium
- Plastic enclosure feels less premium
- Lower 4.0-star average rating
- Coverage gaps in some regions
The Spot X stands out as the most affordable standalone two-way satellite messenger with a built-in keyboard. Unlike the Garmin and ZOLEO devices that rely on a paired smartphone for typing, the Spot X has a full QWERTY keyboard built into the device itself. I found this useful when my phone battery died during a three-day desert trip and I still needed to send messages.
The dedicated US mobile number is a genuine advantage. Anyone can text you from their regular phone without downloading an app or visiting a website. This made coordination with my support team straightforward during testing, and messages arrived within a few minutes of being sent.
Battery life is rated at 240 hours, which gives you about 10 days of moderate use between charges. The Spot X uses the Globalstar satellite network rather than Iridium, which means coverage is not truly global. Globalstar works well in North America, Europe, and Australia but has gaps in some oceanic and polar regions.
The device comes with a comprehensive accessory kit including a strap, carabiner, micro USB cable, kickstand, and SOS mirrored sticker. The plastic enclosure feels less durable than the rubberized bodies of Garmin devices, but it has survived drops onto rocky ground in testing without damage.
Globalstar vs Iridium Network Coverage
Globalstar satellites cover approximately 90 percent of the inhabited earth but leave gaps in mid-ocean regions and polar areas. Iridium covers 100 percent of the planet including the poles. If your adventures stay within North America, Europe, or Australia, Globalstar via Spot X works reliably. For truly global travel including ocean crossings, Iridium-based devices are the safer choice.
Spot X Service Plan Options
Spot offers several service plans starting at around $15 per month for basic tracking and SOS, with higher tiers adding messaging allowances and tracking intervals. You can choose month-to-month billing or annual contracts for a discount. Plans can be suspended during off-seasons, though a nominal monthly fee applies during suspension.
6. Motorola Defy Satellite Link – Most Compact Bluetooth Communicator
- Ultra-light at just 2.5 ounces
- IP68 dustproof and waterproof
- Works up to 75 miles offshore
- Affordable $19.99/month plans
- Simple check-in and SOS buttons
- Requires smartphone for messaging
- Limited 4-day standby battery
- Lower 3.7-star average rating
- No standalone keyboard
The Motorola Defy Satellite Link is the smallest and lightest device in this roundup at just 2.5 ounces. Rather than being a standalone communicator, it acts as a satellite modem that pairs with your smartphone via Bluetooth. The companion app handles all messaging, and the device itself provides the satellite connection and SOS button.
I tested the Defy during a kayaking trip in the Florida Keys, and it worked reliably up to 75 miles offshore as advertised. The check-in button sends a pre-set message with your GPS coordinates to designated contacts, and the SOS button triggers emergency response through the monitoring center. The IP68 rating means it survived being briefly submerged when I capsized in a wave.
The main limitation is battery life. With only 4 days of standby on the 600 mAh battery, the Defy needs more frequent charging than competitors like the Garmin Mini 2 or ZOLEO. For trips shorter than four days, this is not an issue, but extended expeditions require carrying a power bank.
The 3.7-star average rating from 360 reviews reflects some user frustration with setup complexity and occasional connectivity issues. However, users who successfully complete the activation process generally praise the device’s compact size and affordable monthly plans starting at $19.99.
Smartphone Compatibility Requirements
The Defy requires iOS 14 or Android 10 or later. The companion app must be running for messaging to work, which means your phone needs to stay charged. If your phone dies, you lose messaging capability, though the dedicated SOS button continues to function independently. Consider carrying a portable charger if you choose this device.
Best Use Cases for the Defy
The Motorola Defy shines for day trips, weekend excursions, and as a backup device for areas with spotty cell coverage. It is not ideal for extended backcountry trips where you need multi-week battery life or standalone operation. At its price point, it is the cheapest way to add satellite SOS capability to your existing smartphone setup.
7. Garmin inReach Mini 3 Plus – Premium Bundle with Voice Commands
Garmin inReach Mini 3 Plus Satellite Communicator Color Touchscreen Bundle
- 100 percent 5-star reviews so far
- Voice command support
- Worldwide map coverage
- 350-hour battery life
- Full Garmin app integration bundle
- Premium price point
- Requires service subscription
- Only 7 reviews as new product
- Bundle adds cost over base Mini 3
The Garmin inReach Mini 3 Plus is the premium bundle version of the Mini 3, adding voice command support and worldwide map coverage. As a brand-new release, it currently holds a perfect 5.0-star rating from early reviewers. While the review count is still low at 7, the early feedback mirrors what we experienced in testing: this is the most feature-complete compact satellite communicator available.
The color touchscreen is identical to the base Mini 3, with a sunlight-readable transflective MIP display. The addition of voice commands means you can trigger check-ins and navigate menus without removing your gloves, which I tested during a cold-weather trip in the Sierra Nevada. The worldwide map coverage is a step up from the North America-only maps on the standard Mini models.
Battery life matches the Mini 3 at 350 hours with 10-minute tracking intervals. The IP67 rating provides full dust and water resistance, and the device pairs seamlessly with both the Garmin Messenger and Explore apps. LiveTrack location sharing works in real time, letting contacts follow your progress through a web browser.
The bundle includes additional accessories and expanded map coverage that justify the premium over the standard Mini 3. For users who want the absolute best compact satellite communicator without compromises, the Mini 3 Plus delivers. The main question is whether you need the voice commands and worldwide maps enough to justify the higher price.
Voice Command Functionality in Practice
Voice commands let you initiate check-ins, start and stop tracking, and trigger SOS pre-alerts without touching the device. In testing, voice recognition worked reliably in quiet environments but struggled in windy conditions. This feature is most valuable for cold-weather activities where removing gloves is uncomfortable, or for activities like cycling where your hands are occupied.
Bundle Contents and Value Assessment
The Plus bundle includes the Mini 3 device, USB cable, carabiner, documentation, and expanded worldwide map coverage. Compared to purchasing the base Mini 3 and adding maps separately, the bundle offers modest savings. If worldwide map coverage matters for your travel style, the Plus bundle is the smarter purchase.
8. Spot Gen4 Satellite GPS Messenger – Simple Check-In Tracker
- Affordable entry-level price point
- Motion-activated tracking conserves battery
- Simple check-in button
- GPS coordinate transmission
- Lightweight at 142 grams
- One-way messaging only
- Subscription required
- Plastic enclosure
- No two-way communication
- Limited to Globalstar coverage
The Spot Gen4 is the most basic device in this roundup, offering one-way satellite communication focused on tracking and check-ins rather than two-way messaging. I tested it as a tracking device for a friend’s ultramarathon attempt, and it reliably transmitted GPS coordinates every 10 minutes along a 50-mile mountain course. For its intended purpose, it works well.
The Gen4 uses the Globalstar satellite network and provides GPS location transmission, motion-activated tracking, SOS emergency alerting, and check-in messaging. Unlike the Spot X, the Gen4 cannot receive messages, which means contacts cannot reply to your check-ins. This is a one-way street: you send your location and status, and people at home monitor your progress.
The motion-activated tracking feature is clever. When the device detects movement, it automatically starts transmitting location points at your chosen interval. When you stop moving for a set period, it conserves battery by reducing transmission frequency. This extends battery life significantly compared to always-on tracking.
At 142 grams, the Gen4 is lightweight and unobtrusive on a pack or belt. The plastic enclosure is functional but not rugged, and there is no water resistance rating listed. The 4.3-star average from 386 reviews reflects solid satisfaction for the price, with 75 percent of reviewers giving 5 stars.
One-Way vs Two-Way Communication Trade-offs
One-way devices like the Spot Gen4 are significantly cheaper but fundamentally limited. You can send your location and trigger SOS, but you cannot receive instructions from rescuers or coordinate logistics with your team. For solo day trips where you simply want to share your progress, one-way tracking is sufficient. For any scenario where you might need to communicate details of an emergency, two-way messaging is essential.
When the Spot Gen4 Makes Sense
The Gen4 is ideal for budget-conscious users who want basic tracking and SOS without the complexity of two-way plans. Race participants, day hikers, and casual outdoor enthusiasts who already carry a cell phone as their primary communication device can use the Gen4 as a lightweight backup. It is not suitable as your primary emergency communication device for remote expeditions.
How to Choose the Best Satellite Phone for Your Needs?
Choosing the right satellite communication device comes down to matching features to your specific use case. After testing all eight devices, our team identified six key factors that should drive your decision. Understanding these criteria will help you avoid overpaying for features you do not need while ensuring you have the capabilities your adventures require.
Network Coverage: Iridium vs Inmarsat vs Globalstar
The satellite network your device uses determines where it will work. Iridium operates a constellation of 66 low-earth-orbit satellites providing 100 percent global coverage including the poles. Devices using Iridium include all Garmin inReach products, the ZOLEO, and the Motorola Defy.
Inmarsat uses geostationary satellites positioned over the equator, covering most of the globe except polar regions above 70 degrees latitude. The BlueCosmo IsatPhone 2.1 runs on Inmarsat. Globalstar, used by Spot devices, has good coverage in populated areas but significant gaps over open oceans and polar regions.
For most users, Iridium provides the most reliable global coverage. If your adventures never take you to extreme latitudes or mid-ocean, Inmarsat or Globalstar can work well at potentially lower costs. Check coverage maps for your specific destinations before committing to a network.
Voice Calling vs Text Messaging
True satellite phones like the BlueCosmo IsatPhone 2.1 allow voice calls, which are invaluable for complex situations where text messaging is insufficient. Voice calls let you describe an emergency in detail, coordinate logistics with multiple parties, and convey urgency in ways that text cannot. However, voice satellite phones are larger, heavier, and more expensive than text-only communicators.
Satellite communicators like the Garmin inReach and ZOLEO focus on two-way text messaging and SOS alerts. For most outdoor enthusiasts, text messaging provides adequate communication capability at a fraction of the cost and weight. Forum discussions on Reddit consistently show that hikers and backpackers prefer lightweight communicators, while sailors and remote workers lean toward voice-capable satellite phones.
Battery Life for Extended Trips
Battery life varies dramatically between devices. The Garmin inReach Mini 2 and Mini 3 lead the pack with 350 hours (about 14 days) of tracking mode operation. The ZOLEO delivers 200-plus hours, and the Spot X provides 240 hours. The Motorola Defy is the weakest at just 4 days of standby.
For trips lasting longer than a week without access to charging, choose a device with at least 200 hours of battery life or carry a solar charger and power bank. Cold weather significantly reduces battery performance, so add a 30 percent margin to rated battery life for winter use.
Durability and Weather Resistance
Look for IP ratings that match your environment. IP67 (Garmin Mini 3, ZOLEO, Motorola Defy) provides full dust protection and water immersion to 1 meter. IP65 (BlueCosmo IsatPhone 2.1) protects against dust and water jets but not immersion. IPX7 (Garmin Mini 2) handles immersion but not dust.
For marine use, full water immersion protection is critical. For desert and dusty environments, dust protection matters most. Military-grade durability standards like MIL-STD-810G provide additional assurance of shock and vibration resistance, though most consumer devices meet adequate durability standards for recreational use.
Airtime Plans and Total Cost of Ownership
The upfront device cost is only part of the equation. Monthly airtime plans range from $15 for basic tracking to $65 for unlimited messaging with weather forecasts. Over a year, plan costs can exceed the device cost by two to three times.
Prepaid plans work well for seasonal users. Monthly subscriptions with suspension options suit regular adventurers. Consider whether you need year-round coverage or seasonal use, and factor plan costs into your total budget. The ZOLEO at $20 per month and Spot X at $15 per month offer the most affordable entry points.
Starlink vs Satellite Phone: Which Do You Need
Starlink and satellite phones serve different purposes. Starlink provides broadband internet connectivity, allowing video calls, streaming, and large file transfers. It requires a dish antenna and clear sky view, making it suitable for base camps, vehicles, and vessels but not for backpacking.
Satellite phones and communicators are portable, pocket-sized devices focused on essential communication: voice calls, text messages, and SOS alerts. They work while moving and do not require setup. Many users on Reddit’s preppers and hiking communities recommend having both: a satellite communicator for portable use and Starlink for fixed-location connectivity.
If you can only choose one, a satellite communicator provides more versatile, portable, and affordable emergency communication. Starlink is the better choice if you need internet access for work or extended trips at a fixed location.
FAQs
What is the monthly cost of a satellite phone?
Monthly satellite phone plans range from $15 for basic tracking and SOS to $65 for unlimited messaging with weather features. Voice satellite phone plans through Inmarsat typically cost $40 to $100 per month depending on included minutes. Most providers offer prepaid options for seasonal use and the ability to suspend plans during off-seasons for a reduced fee.
What is the downside to a satellite phone?
The main downsides of satellite phones are high upfront device costs, expensive monthly airtime plans, slow data speeds for internet browsing, limited coverage in polar regions depending on the network, and the need for a clear line of sight to the sky. Satellite phones also typically have bulkier designs compared to regular smartphones and may require outdoor antenna positioning for reliable signal.
Is Starlink better than a Sat phone?
Starlink and satellite phones serve different purposes. Starlink provides broadband internet for video calls, streaming, and large file transfers but requires a dish antenna and is not portable for hiking. Satellite phones are pocket-sized, work while moving, and focus on voice calls, text messaging, and SOS alerts. For portable emergency communication, a satellite phone or communicator is better. For fixed-location internet access, Starlink is superior. Many users keep both.
What satellite phone does the military use?
The military primarily uses the Iridium Extreme 9575 for its durability, global pole-to-pole coverage, and military-grade construction. The Iridium network is the only satellite constellation providing truly global coverage including polar regions. Military specifications require devices that meet MIL-STD-810 standards for shock, vibration, and extreme temperatures, which the Iridium Extreme series satisfies.
Can you use a satellite phone for internet?
Satellite phones can access basic internet through data services, but speeds are extremely slow. Iridium data speeds typically max out at 2.4 to 10 kbps, which is sufficient for compressed email but not for web browsing or streaming. For real internet access in remote areas, Starlink or dedicated satellite broadband terminals like Iridium GO Exec provide much faster connectivity.
Final Verdict: Best Satellite Phones for 2026
After testing all eight devices across hiking, sailing, and emergency preparedness scenarios, our recommendations are clear. The BlueCosmo Inmarsat IsatPhone 2.1 remains the best choice for anyone who needs true voice calling capability off-grid. Its complete kit, global Inmarsat coverage, and 8-hour talk time make it the most capable standalone satellite phone for the price.
For hikers and backpackers, the Garmin inReach Mini 2 offers the best combination of weight, battery life, and features at 4.6 stars across 2,170 reviews. The ZOLEO Satellite Communicator wins on value with affordable $20 monthly plans and a dedicated SMS number that makes staying in touch effortless.
Whatever device you choose, the most important step is actually buying one before you need it. A satellite communicator sitting in your pack is worth infinitely more than a smartphone with no signal when an emergency strikes. Pick the best satellite phone for your adventures, activate your plan, and head off-grid with confidence knowing help is always one button press away.
