How do we check compatibility?
Your IMEI returns the frequencies bands supported by your smartphone. Our tool is querying the two majors carriers: T-Mobile and AT&T. We are directly getting the response from them.
Due to recent mobile network upgrades your phone needs to be at least compatible with 4G LTE frequencies bands used in North America. Since 2022, AT&T and T-Mobile does not operate in 2G & 3G anymore.
There is always a small chance of an error or false positive.
Don’t hesitate to reach us by chat or email with your brand and exact phone model or IMEI so we can double check the compatibility.
