Unlocked Nokia 6200 - help troubleshoot
need an advice on troubleshooting an unlocked Nokia 6200 (originally AT&T), got it on eBay. I am using Cingular SIM. With SIM card in, phone activates and finds Cingular network (Los Angeles area). However, when making or receiving call, there is no audio coming from either earpiece/loudspeaker/headset. People on the other end also do not hear anything.
The speaker is working, as FM radio mode works OK.
Please help to troupleshoot. Here is firmware info if it helps:
