Satellite phones and plans are expensive, but if you’re OK with limiting your communications to text, then the ZOLEO Satellite Communicator is an extremely affordable when traveling beyond cellular coverage zones. What makes the ZOLEO different is that you get a dedicated SMS number that works whether you’re in or out of cellular coverage. You also get a unique email address that follows you around the globe. Unlike other networks, you get long messages with the ZOLEO, up to 950 characters.
