This phone will work with any AT&T MVNO such as Cricket without being unlocked, however if you wish to use it on T-Mobile or any of their MVNO's it's important to know that this model is incapable of acquiring band-12 700MHz LTE.
This map shows areas that do not have 700MHz LTE due to DTV 51 protection such as Los Angeles, Phoenix, San Francisco and more (so the lack of band-12 doesn't matter here, ever)
Notable features the AT&T version is lacking compared to the T-Mobile variant are:
No Band 12
No WiFi Calling (yet)
*#06# to retrieve the IMEI
##634# for the lifetime menu
##7820# for the unlock menu
##3282# for the engineering menu
