I just upgraded my phone from an original Motorola droid to a droid bionic. My wife uses a "dumb" Samsung flip phone. I tried to get Verizon to switch her number to the original droid, but they said I would have to have a data plan at $40/month. My question ... Can I just move the sim card from her dumb phone to the droid and then use it as a phone and have data capabilities when she's hooked up to wifi?
