Hello all. I originally got a Bold 9700 then got the Captivate. I still have the Bold. I was wondering if I was to switch the SIM card to the Bold, would The bold still function all as normal? I have unlimited MMS, SMS and the 200MB Data Plan. Im wondering about this? I might like to swap out here and there. Im new with AT&T. Always been a Verizon Subscriber and they dont have Sim cards. Thanks guys.
