If I buy an unlocked T-mo Z10 for use on the AT&T network, will I be able to connect across all bands? If so, will performance be equivalent to an AT&T device?
I spend a lot of time abroad (mainly in Latin America) and a number of countries I spend time in don't have wide LTE coverage. I want to be able to turn the LTE off for battery reasons, but also want my core AT&T service to work at full speed in the states.
Any thoughts? Thanks!
