Hello I believe I'm being blocked by an ios7 user. I'm wondering if other users here could help me figure it out? Here my situation. When I call my friend it goes straight to hid voicemail. I believe this means he could be blocking me but it could also means his battery is dead. When I text him instead of it being sent as a usual iMessage in blue, it's green and is "sent as text message" I don't know if this means he's blocking me or if his phone could be dead. Does anybody know the details of how it works?
