I have the same problem with my T-mobile Sim card !
I have been able to check this issue with another T-mobile SIM and everything was perfect.
I have been on the phone with a T-mobile tech guy for 40 minutes but could not figure out why!
It seems that there is a problem with the combination of a particular T-mobile sim card and the Treo 650.
I could not identify what particular kind of SIM card.
Your only chance is to replace the SIM while keeping your phone number and see if it works.
I had bad luck: changed the SIM (paying 25 $) and keeping my phone number and having the same problem...
Hope you have an altrenate solution....
