I have two orange contract phones and have the same problem with both [so it's not a phone fault] Have a 4-5 bar signal, but will not connect to outgoing or incoming calls, nor send or receive messages. Contacted orange CS, told to take out batteries and sims then should work. It doesnt! Anyone else having similar problems or can explain?
Thanks
[feels angry call to Orange CS coming on!]

What's happening when you dial out, or to callers dialling you?

Several people I know on orange regularily miss calls even though they have full signal.
