How easy it is travel abroad with the Verizon model of the new iPad?

Question

On the specs listed on Apple's site for the new iPad, it lists GSM frequencies under Verizon model as well !!!
I am sure that one can't use AT&T SIM on the Verizon model, something must have been locked to prevent that.
But does anyone know how easy it is to pop in a foreign country 3G GSM micro-sim when travelling abroad into the new model Verizon iPad?
I have already ordered an AT&T model, but later realized that even the Verizon model shows GSM capabilities. If I could find conclusively about the foreign 3G GSM freedom on Verizon, I will definitely exchange my AT&T model for a Verizon one.

Answer 1

I don't think CDMA uses SIM card at all, hence no SIM slot in ipad 2 VZ model.
But LTE requires a SIM card, the VZ model of the ipad 3 is forced to have a SIM slot.
Here's an FAQ page from VZ site talking about LTE SIM:

It's good (I am hoping truly that's the case) that Apple also allowed 3G GSM capability, this means one can pop out the VZ LTE micro-SIM and pop in any 3G micro-SIM.
I think there might be some lines of code from Apple to at least prevent an AT&T micro-SIM to work on a VZ ipad 3 just to prevent VZ from getting upset.
But other 3G micro-SIM's should work on VZ model. We can only find out on the 16th.
Here's one article that talks in details on this topic:
