3G H+ (UMTS) Sunsetting in 2022
AT&T shut down its 3G network in February and T-Mobile will do by July.
What does this mean?
Your smartphone need to be fully compatible in 4G LTE on these networks or it will not connect anymore. This may be the case for some budget smartphones bought outside the United-States.
2G & 3G
Say Bye!
Due to recent mobile network upgrades and the complexity of the technology your phone needs to be at least compatible with the carrier 4G LTE bands / frequencies.
Since 2022, AT&T and T-Mobile does not operate in 2G & 3G anymore.
Partially Compatible
This means your device doesn’t have all the required bands to fully work with the carrier. Connectivity may vary depending of the exact location. This compatibility is not recommended.
