I'm trying to unlock my nokia 6103 - t-mobile, usa IEMI 354814010822746 I need the master security code - the default does not work (12345) nor does 0453512677 which is what one of those generators gave me. I'm not sure if what I'm after is ultimately possible though: I want to manually select the network (force roaming) -- I moved and ever since, my calls have been dropping like crazy & call quality has been poor - I'm wondering if I manually select another available network I'll see improvement. when I try now, I get an "unavailable" message, bars drop to zero for a few seconds, and then go back to one or two after a bit... Thanks
I think you may have moved to a place that has what I would call a "sucky tower" and it's not very close by. As for the security code, you have tried the only two that we could possibly come up with. Either way, with the code or even an unlock code, you won't be able to force roaming and get any better of a signal.
