Question from a curretnt Treo/Goodlink and prospective BB user: If I have 2 SIMs both enabled for a BB data plan, can I switch them in one BB unit and get my BES mail without any reprovisioning? This definitely will not work on a Treo with GoodLink. GL is keyed to the telephone number. Thanks.

Yes, the BES doesn't care what provier you are using. It pushes data to a pin not a phone number. (providing they both have BB data plans as you state.)

Shouldn't he need BB unlocked to use it with the SIM from the different carrier?

He didn't mention different carriers.. He could have two SIMs (personal and business) from the same carrier...

Thanks for the response. I have two Cingular SIMS--one personal and one business--I plan to get BB service on both.

Switching SIMs will be seamless in that case.
