In this case it can be some hardware issue with your phone.
If your phone was pre 4.24 software version and it was upgraded it is 
possible to have a corrupted EEPROM and you need to use some software 
tools to repair it.

If that is not the case you can try to identify what hardware component 
is broken by manually pickup a 900 or 1800 operator and check it if it 
works. If one is working and one not this means your duplexer has issues 
and needs to be replaced. Other components that might have issues are 
the PA and COBBA ICs. Considering that a 3310 you can get for free now 
it's not worth it to repair it.
