Satellite Phone Frequently Asked Questions

Why Use Satellite Phones?
Because cellphone towers have a limited reach cellular networks offer coverage only in densely populated areas. Once you leave these areas, besides satellite networks, there is no other network offering reliable communication. For this reason, we have satellite phones that work anywhere in the world. They offer reliable Voice, Text, GPS, and SOS and do an excellent job keeping you connected anywhere at sea, on expeditions, long hikes, remote job sites, mountains, deserts and anywhere humans have stepped foot on.

Should I rent or buy a satellite phone?
If you need a satellite phone for more than 1 month of the year or multiple times a year it is recommended to buy a satellite phone instead. If you only need a satellite phone for one or two weeks at a time, renting one would be a better option.

How fast can I get a satellite phone?
We can deliver a satellite phone to you as fast as the next day if major shipping companies offer that service to your area. In critical and emergency situations we can often deliver the device to you the same day via courier.

What is Rollover minutes?
Rollover is an option to roll the unused minutes from this month to the next one and accumulate your unused airtime for later use. This option costs $10 per month.

What is a USA phone number?
Satellite phones use international phone numbers and most cellphone users don’t have international calling activated with their carrier. A USA phone number redirect the calls to your satellite phone and allows anyone to reach you free of cost for them, but it will burn minutes from your plan. This option is available only on monthly service plans and costs $10 per month.

What is coverage like in south pacific (aus, nz, fiji, somoa, tonga, and south america, galapogous is. etc.)?
Satellite phones offer excellent coverage in all of these areas and you will experience uninterrupted service.

Can satellite phones send and receive text messages?
Yes, satellite phones work great with SMS services and you are able to send and receive text messages. Additionally satellite phone providers have dedicated pages where anyone can use their service to send free SMS to your satellite phone.

What is the cost for calling internationally?
Satellite phones are not subject to roaming costs. You are able to make calls anywhere in the world to any cellular or landline at the same flat rate cost.

Do satellite phones work in the ocean?
Yes, both Inmarsat and Iridium satellite phones offer excellent coverage in the ocean.

What is the lowest cost I can pay for a satellite phone and a plan?
We recommend buying the Inmarsat IsatPhone 2 at a special price of $395 with a 50 minute monthly plan of $49.95 per month

Will I get charged for incoming calls and text?
No, incoming calls and text are FREE on any service plan you choose.

Can I get internet on a satellite phone?
Satellite phones do not provide sufficient data connection to use internet services on your device. For internet use we recommend satellite internet devices like BGAN explorer 510 or IsatHub Isavi.

Can satellite phones be used indoors?
Satellite phones need a clear line of the sky out in the open to work. There are however satellite phone accessories such as antennas and docking stations that allow your satellite phone to work indoors.

Can my satellite phone be traced and spied on?
It is very hard to trace and spy on a satellite phone. Eavesdropping on a satellite phone is virtually impossible since the signal travels vertically towards the sky - compared to cellphones where the signal travels horizontally towards the cellphone towers and through this transmission it can be intercepted and decrypted.

How does SOS emergency feature work?
When the SOS button is pressed a preconfigured notification sequence is activated and GEOS 911 services are contacted and your GPS coordinates are sent out. GEOS will attempt to call you immediately to coordinate a rescue mission to your location. Additionally if preconfigured your family members will be notified about your situation.
