3310 no signal problem and solution

Hello again dear readers!  Today is an old school repair from an old model the great 3310 in the old days.

This was brought to me by my customer with a dead battery.  Upon inserting a new battery phone has power but no signal.  Using the phone setting I tried to manual search but no luck there was not even  a single service provider available.

Problem was solved by replacing the antenna switch:  see my picture below.
