Satellite communicators are among the most globally useful pieces of outdoor safety gear — they function in locations where no local communication infrastructure exists. Here's what changes and what doesn't when traveling internationally.
Network Coverage Outside North America
Iridium devices (Garmin inReach, Zoleo, Bivy Stick, Somewear): Work identically anywhere on Earth. No roaming charges, no coverage gaps, no plan changes required. The same monthly subscription covers international use.
Globalstar devices (SPOT): Coverage is strong in most mid-latitude populated regions internationally but has gaps in polar areas and some remote high-latitude destinations. For standard international hiking — Patagonia, the Alps, New Zealand, Nepal — Globalstar coverage is usually adequate.

Full Review →PLBs for International Emergency Backup
A PLB registered with NOAA works as a distress signal in any country. The COSPAS-SARSAT system routes distress alerts to the relevant national rescue coordination center regardless of where the beacon activates. For travelers who want an emergency backup with no subscription concerns or account management while abroad, a PLB is the most straightforward option.

Full Review →Charging Internationally
All USB-C and micro-USB satellite communicators charge from standard USB power adapters with a plug adapter for the local outlet standard. A universal USB charger handles this for any destination. SPOT Gen4 runs on AAA batteries — standard alkaline available globally, with lithium AAA available at outdoor stores in most countries.
Frequently Asked Questions
Does my Garmin inReach work in other countries?
Yes — Garmin inReach uses the Iridium network, which provides 100% global coverage. The device works in any country without any roaming charges or additional plan changes. The subscription plan purchased in the US covers international use on the same monthly fee.
Do SPOT devices work internationally?
SPOT devices use the Globalstar network, which provides good coverage in most mid-latitude countries but has gaps in polar regions and some remote international areas. For travel within Europe, Australia, Southeast Asia, and Central/South America, Globalstar coverage is generally adequate. For polar expeditions or very remote international destinations, Iridium is the safer choice.
Does a US-registered PLB work in other countries?
A PLB registered with NOAA transmits a distress signal via COSPAS-SARSAT regardless of location — the system is international by design. Rescue coordination in a foreign country goes through that country's rescue center; COSPAS-SARSAT routes the alert appropriately. No registration change is needed for international travel.
Are there countries where satellite communicators are restricted?
Some countries restrict private satellite communication devices. Check current regulations for specific destinations before travel — Russia, China, and a handful of other countries have had satellite device import or use restrictions. This is a rare concern for most international hiking destinations.
