ok, so my parents took my phone off me a few months ago because i was sending 'inapropriate texts' to my girlfriend. (i have a samsung tocco lite btw) Yesterday they gave it back to me because i am at a sleepover. I went to text one of my friends but it said 'network settings unavailable.' Could this just be because I am at my mates house or not? Will it work when I'm at home? My mate sent me a text in the same house as I was in when it was saying this and it worked for him and i recieved it, but i dunno. I definately haven't changed any network settings and i don't think my parents have but if they have, how do i change them back? Thanks in advance!
