Bold 9900 or 9930 to go between USA and Canada?
I am looking to upgrade to the Bold 9900/9930, having had my old Bold 9000 for a while now. I live in Canada, but will be attending school in the US this fall. My plan is to switch between my Rogers SIM card and an American SIM card (Verizon is supposed to be strongest in my area, followed by AT&T). A couple questions:
1) Is this possible to do?
2) Should I get the 9900 (with Rogers in Canada) or the 9930 (with Verizon in the US)? Or would either work in this case? I understand that the 9900 uses a SIM card, but I'm not sure that the 9930 does.
3) Is there a better option for traveling constantly between the US and Canada? (What exactly is Verizon's Nationwide Plus Canada plan?)
Any help is appreciated. Thank you very much.
