Unlocked Galaxy Note II - 7 months a year with Koodo in Canada, 5 months a year with compatible carrier in USA. Feasible? or am I asking for trouble. I know some APN network settings will have to be changed and each service provider needs its own SIM card, but what are the chances I will be up the creek with no service after switching from one to another? Or can it be as simple as shutting down the phone, swapping the SIM card and updating the APN config.. then being good to go after a reboot. Would like to hear experience of other community members.
