I've tryed the DFU mode then restoring that doesn't work. What else can i try ?

Now my sim card can't connect to my network and i've been told that with a pay as you go sim card you need to go into settings but i can't.
Guys i really need help getting out of emergency mode. Shall i get take it to my nearest o2 shop and get it fixed ?
