Nokia 6100 wont make outgoing calls.

[nimicitor]

What can I try?
The signal strength is always half way, where as my 5140i always has full signal on the name network.
Incoming calls rarely get through either and text messages take ages to arrive.
I have a T5 driver ready if I need to take it apart.

Thanks for any help.
