Check the Delorme InReach. It uses the Iridium satellite network and claims 100% global coverage. They're comparably priced to the SPOT and, when paired with an iOS or Android phone will do two way text. As a standalone, it'll do three pre-programmed messages and emergency activation. A new model will do two way text without the need for pairing.

None of the views expressed here in any way represent those of the unidentified agency that I work for or, often, reality. It's just me, fired up by coffee and powerful prose.
