Help please. Cannot send or receive text messages
First post, so, firstly, hello! I've been using this website for a while, you guys make some awesome themes and home screens!
As of last night, I cannot send, or receive, any text messages (SMS). I never send MMSs so I don't know if that works either. I've tried restarting the device, removing + inserting the SIM card, turning mobile signal off and on again, and nothing seems to work!
I'm on the HTC S620
It's essential for work that I can stay in touch by text message, and unfortunately, I can't find anywhere else that can help me.
