Issue with T-Mobile connection

I have a MaxTransit 5G with an AT&T and TMobile sim card. When using the TMobile SIM, the connection randomly drops and reconnects, several times a day, regardless of locations. This does not happen with the AT&T SIM.

Any suggestions?

what do the logs show?

it could be using a weak band, look at what it’s using and take it out of the config and keep trying. ATT band 12 is terrible for me but ATT loves to use that as a primary band with only 1mbps, i took that band out, and now get great speeds all the time
