That is kind of stange. I agree with the sim technology if you are traveling but not being able to use your cdma phone does not seem right.

I went to england and checked with sprint about using my sprint service overseas. They stated (at the time) I could not use their service but I could activate over there as long as it was a dual or tri mode phone and use it in England.

My first Motorala flip phone had a contract in Dallas and I added a local number in my area. It would not work on both at the same time but I could switch back and forth.
