Hi, I've been having a wierd problem with my phone today, at first today i noticed i couldn't log onto the network even when i had a strong signal, i thought nothing of it at first but i travelled a mile and couldn't log on at all over that distance. So I tried switching it off and on again, and it logged onto the network, but now I can't send or recieve texts! I can still make phone calls, but texts just come up with an error, i think it might be something to do with my account as it seems to do the same when i put it in my gfs phone. A little blue arrow has appeared on the main screen, but i don't know what that means. Anyone know what's wrong?
Sent em an email but it'll take em a while to respond
