Use of Samsung Galaxy a52s 5G smartphone.

As long as you have the correct size of sim card and the phone has the correct bands.

Thanks Gramps, I am not sure of the SIM size on new phone, but the bands are 5g (under 6GHz ) and 4G LTE for the new phone.

Also, this is an international phone, not one sold by T-mobile (USA).

You need to check the bands and make sure it's VoLte compatible with TMobile.

Try checking XDA forums for that phone.
