Hey all,
Last year I was on ATT and pre-ordered a T-mobile phone because the phone I originally wanted was not available under the t-mobile tag in the store, assuming they had smaller stock. I was able to swap my SIM in the store and everything worked great. This year however, I'm on T-mobile and was forced to pre-order an ATT phone through the upgrade program. I'm assuming that swapping the SIM will work because technically they should be unlocked through the upgrade program. Both are GSM, so would there be any issues with this? Any information would be super helpful. Thanks in advance!
