Could you explain what the *777* does, and after I restart my phone, do I choose to ignore sids? What should I see on the display of my phone if it is working properly. I chose ignore, and now have a T on the display by the signal strength. Is that right? It is not clear to me, who doesn't know sid's, how to take advantage of this feature that is available.
You can change the network protocols the phone subscribes to - GSM or TDMA, both, one or the other, etc. Go to Settings, ->Networks -> Protocol Stack -> then pick your network. This is one thing you can do to an unlocked phone. It is useful for testing signal strength for one protocol or the other or switching to TDMA when GSM is barely giving a signal but just enough for the phone to hang onto GSM.

I used the *777*-and a G or T shows up beside the signal strength, but it does NOT stay on a G or T but switches between the two-dropping calls each time it switches. And I cannot seem go back to NO G or T showing up.--How can I make it stay on G or T only and stop the constant switching.
Cingular Tech said the calls should not drop--but switch seamless. Swapped the phone for another, but reluctant to *777* the new one. Does this mean that my T62u is "locked" and the *777* will not work on a "locked" phone?
I just got another T62U from Cingular under the 1 year phone warranty. My first phone lasted all of 2 weeks, It replacement lasted almost a year. I was able to put the *777* into my 2nd phone but like your new one, the phone would not take the code. I called sony and they gave me a code which will open up the network part of the setting tab. I don't know if it totally unlocks the phone, but I now have protocol stack and was able to put in the *777* code. Let me know if you want the code.
