A:AnswerNo, this device does not come with a SIM Card, but I believe BB can support or provide one for Verizon and AT&T, possibly for an additional cost.
A:AnswerI think so. But 1. It isn't pretty. and 2. It's annoying.
It isn't flawless. I found issues with group notifications, or people responding and I would get a text from their number directly instead of in the group chat.
Hope this helps.
