A:Answer It is supposed to be able to do this, but I haven't tried it yet. Because Best Buy sells these phones as unlocked, you can always buy a SIM card and use it in this phone without a problem. This means you can easily switch from one carrier to the next and when I go overseas, I can buy a SIM card in Europe and use that phone number while I am there which is cheaper than the $10/day Verizon would charge me to activate my phone for International calls. Talk to the Best Buy people selling the phones as they support the different carriers, but aren't on commission like the Verizon/AT&T corporate stores. I seem to get a better deal on my phone at Best Buy and they aren't trying to push me one way or the other.
