| | Swap T-Mo to Cingular - Changing Handheld without Calling Support
Please Login to Remove!
I just bought a BB 8100 on T-Mobile. I used it initially with the RIM data plan on T-Mobile.
At the same time I already had a BB account @ Cingular. My plan was to swap my 8100 off T-Mobile (weak signal at my house) onto Cingular.
What I found was that after I got the 8100 activated on T-Mobile, I removed the SIM from my 8700 Cingular and put it into the 8100. Instantly my BES started working.
When I went into the Cingular BIS site, I put in the new PIN AND IMEI and it simultaneously removed it from the T-Mobile site.
No need to call T-Mobile and have them blank the PIN out.
It appears that so long as you have the PIN and IMEI that you can freely bove between carriers without having to un-enroll (for lack of a better description) from your old carrier.
