Satellite Phones

Satellite phones provide voice, SMS, and data services anywhere on the Earth and they do not have to rely on cell phone networks. Now available at Grandhub in Nairobi, Kenya.

Many offer data services but few offer internet access and most have very limited bandwidth. However, many popular online functions can be carried out with an added accessory to a standard phone.

Satellite phones require line-of-site with the sky to receive a signal for service. Don’t expect your satellite phone to ring in the lobby of your hotel or inside a stateroom while at sea. However, you might be able to receive a signal if you are by a large window or in an open, remote spot. Hardened structures, buildings, mountains, and heavy tree cover can all negatively affect your signal. Pilots often leave a satellite phone or an Iridium GO! on the dashboard of their plane’s cockpit to receive a signal.

Inmarsat and Iridium satellite phones can send and receive text messages (SMS) or short emails, making satellite communication quick and easy. Globalstar phones can only receive messages up to 35 characters, but cannot reply.

Satellite phones play a critical role in scenarios where traditional communication infrastructure is unavailable or compromised. They are used in industries like maritime, aviation, oil and gas exploration, and scientific research. As well as by government agencies, as well as by individuals who venture into remote and off-grid areas. While satellite phones offer a lifeline in these situations, they are generally not used as primary communication devices.
