Make sure the SIM card that comes with a new phone purchase, is activated and installed into your new phone. Swapping a SIM card from your old phone to a new phone does not produce the desired results.

Been a T-Mobile customer for almost 15yrs. Recently I upgraded to a Samsung A52 5G from a Samsung J7. The sales person helping me took the SIM card from the J7 and installed into the A52. First I noticed the A52 battery was draining way faster than my J7 did, and I was having issues sending/receiving text msgs - when I went back to store, sales/customer service reps said that phone and battery were behaving as expected?!?!? Then I received a notification message that I could not clear: Carrier Hub “MCM client requests are processing:….  however my A52 phone did not have this APP installed therefore I could not uninstall as advised. Finally, another trip back to the store talked to a different sales/customer who suggested that the issues may be caused by an incompatible SIM card. Viola! Once they activated the SIM card that came with the A52 phone and installed it, I no longer have battery draining or text messaging issues OR Carrier Hub notification msgs. Not all Samsung SIM cards are equal

might also depend on whether your J7 was 5G capable or not..if it was not then it would need a SIM card that is 5G capable.
