Hi everyone,
For the past week or so, I've been experiencing lower signal strength in areas that I normally have 4-5 bars, as well as have times where some (but not all)incoming calls automatically go to VM without my phone even ringing (even though I have an adequate singal). I called AT&T and explained all this to them. The guy came back telling me that I have an older sim card that goes too slow, so I need a new one. Does that sound like those problems would be caused by a sim card? Thanks for the help!

Although is does sound like one of those easy answers from a CSR, it could be the problem. A couple of years ago my BB was having a problem holding a signal where it had always been perfectly strong, and it was suggested to swap SIMs and I thought "oh sure". But it worked.

Can you visually describe the SIM that you have? Color / markings etc. Maybe the first 5 digits of the SIM number or so?

even if it's a newer SIM card...sometimes the SIM card just goes bad. don't ask me why...maybe info gets corrupted on it? i've had to replace my SIM card twice already in my Blackberry 8700g. no no...i don't take it out and fiddle with it on my spare time lol...maybe t-mobile just buys crappy SIM cards from a crappy supplier in china
