HMD OffGrid Satellite Tag for iOS and Android

Why the HMD OffGrid Matters

Three days into a hiking trail. No bars on your phone. The person waiting at home has not heard from you since yesterday. There is no way to send a message, share your location, or call for help if something goes wrong. For millions of hikers and adventure travelers worldwide, that is not a hypothetical. It happens every weekend.

The HMD OffGrid was built for exactly that gap. It is a compact satellite communicator — 60 grams, roughly the size of a credit card — that pairs with any iOS or Android smartphone via Bluetooth and adds satellite messaging, live GPS tracking, and emergency SOS without needing a single bar of cell coverage.

What separates it from existing solutions is one word: any. Apple's satellite features work only from iPhone 14 upward. Google's SOS is largely limited to the Pixel 9 series. The HMD OffGrid works with every phone outside those boundaries — a universal satellite layer that sits in your pocket regardless of what device you carry.

How HMD OffGrid Fits Into Your Daily Life

Once paired through the free HMD OffGrid app, four functions become available anywhere on the planet:

• Two-way satellite messaging — send and receive texts up to 140 characters, just like standard SMS
• One-button check-in — press the physical button on the tag to send a pre-set "I'm safe" message to contacts, no phone interaction needed
• Live location sharing — real-time GPS coordinates sent via satellite to up to five contacts, trackable from home
• SOS emergency alert — press and hold to contact Overwatch x Rescue™, coordinating 10,000 rescues annually across 940 agencies worldwide

The tag itself is built for the places where you need it most. It carries an IP68 weatherproof rating, MIL-STD-810H military-grade durability, and draws positioning data from GPS, Glonass, Galileo, and BeiDou simultaneously. Battery life is three days. Charging is USB Type-C.

Critically, the SOS function works even when your phone is dead or disconnected — the tag operates independently when it matters most.

The Bigger Shift This Device Represents

Satellite communication used to mean one of two things: a $3,000 dedicated satellite phone, or a feature locked inside a specific flagship model. Neither option worked for the average person heading off-grid for a weekend with the phone already in their pocket.

The HMD OffGrid separates the satellite layer from the handset entirely. It travels with any device, upgrades any existing phone, and outlasts any single upgrade cycle. That shift — from built-in feature to universal accessory — is what makes this genuinely different from anything before it.

Two subscription plans cover different usage levels. HMD Freedom offers up to 350 messages per year plus SOS access at €95.99 annually. HMD Unlimited delivers unlimited messaging at €167.99 per year. Live location tracking is an optional add-on at €5.99 per month on either plan. Coverage spans North America, Canada, Europe, and Australia/New Zealand.

Q: Do your contacts need the app to track your location?

Yes — contacts receive updates through the free HMD OffGrid app, but no subscription is needed on their side. Only the tag owner requires an active plan.
