Frequently Asked Questions
If your expedition involves remote areas with little or no mobile coverage, a satellite phone can provide a reliable way to stay connected for safety, logistics, weather updates, and emergency communication.
Satellite phones support live voice calls and SMS messaging, while satellite messengers are typically focused on tracking, SOS alerts, and two-way text communication. Many expedition teams use both depending on the environment and communication requirements.
Iridium is often the preferred choice for expeditions because it offers truly global coverage, including polar regions and open oceans. Other networks such as Inmarsat can also perform well depending on your destination and route.
Yes. Many expedition satellite phones are designed for demanding environments and are used regularly in polar, mountain, offshore, and desert conditions. Battery performance can still be affected by extreme cold, so carrying spare batteries or external power is recommended.
Satellite phones require a relatively clear view of the sky to maintain signal. Deep valleys, dense tree cover, cliffs, or heavy obstructions can occasionally impact connectivity.
No. Some countries restrict or regulate the use of satellite communication devices. It’s important to check local regulations before travelling internationally with a satellite phone.
Battery life varies by device and usage, but many satellite phones can provide several hours of talk time and multiple days of standby time. Power banks and solar charging solutions are commonly used on longer expeditions.
Yes. Many teams rent or carry shared satellite phones for group coordination, emergency contact, and scheduled check-ins with support crews or family members.
