Figure 13 Troubleshooting when the "Contact Service" message is seen
The phone does not register to the networks, or the phone cannot make a call
Context
If the phone doesn't register to the network, the fault can be in either BB or RF. Only few signals can be tested
since several signals are 'buried' in one or more of the inner layers of the PWB.
First, check that SIM LOCK is not causing the error by using a Test-SIM card and connect the phone to a tester.
