When I went into the Verizon store the guy said he had done something with the SIM card so that the phone would be ready to function abroad. I spend a good part of my year out of the country and he suggested that I call tech service and get them to unlock the phone so that it could be used with SIM cards from other service providers. I was reading on here about people getting unlock codes, but don´t know if the code they get enables them to use other companies SIM cards or if it´s the same thing the guy in the store did for mine. I have a SIM card from a non-Verizon/Vodafone company that I can test with, but I´m afraid that it might mess something up if I just start popping in and taking out cards. Help? Thanks!
