Have an old Moto E , replaced with a G


,Traveling to Mexico need to unlock that phone for temporary use with ATT


That is not possible. In addition to the phone being unlockable, it wouldn’t have the right type of cellular radio for use on AT&T.


Will buy a phone from ATT in Mexico


If you replaced the E with a Moto G and it is supported by Republic on the My Choice plan it is unlocked and you should be able to add an AT&T SIM that is usable in Mexico … see this from @rolandh


the real question needed to answer this is which Moto E (1st, 2nd, 4th, 4th Plus) which was replace by which Moto G (1st, 3rd, 4th, 4th Plus, 4th play, 5th Plus, 5th S Plus)


Looking at the motoE there is no place for a Sim card,so appears I am out
of luck.
I am keeping the Moto g with republic
,The version of this device is not important
Just a singer in a Rock and roll band

Stay calm and speak Catalan
