I plan to get the new iPad4 (AT&T version) from the Apple store here in the U.S. Please correct me if I am wrong in my understanding. This iPad is unlocked & comes with an AT&T SIM chip. When traveling in Europe, I will be able to swap out the SIM for a country-specific SIM for use on that carrier's network in that country. Is my understanding correct so far?
Again, correct me if I am wrong, in the U.S. the iPad will operate on AT&T's 4G network only. It will NOT work on any 4G network in Europe. However, it will operate on any 3G network in both North America & in Europe. So, the question I have is: do most cell carriers in Europe use 3G or 4 G networks? Thank you for your help.
