I received a call early in the morning around 7am, today 4/18/13. I was on the phone already and didn't pick it up. No message was left. I called it back and immediately got the message 'your service is activated on the global com network' No idea what that is all about but I hope it doesn't mean I'm going to be paying for something I didn't sign up for. I called Sprint and the operator called it too and got the same message followed by a hang up. She assured me it is not Sprint and noted my account in case I receive any charges.
Received a call from 312-334-3000 while on another call. I dialed this number and heard the message that this was handled through the Global Com Network. Did a search on this "network" but nothing listed so am assuming this is a spammer. BEWARE!
