I just purchased a GSM unlocked Samsung s10e. The phone was orginally a T-Mobile phone but my SIM is for AT&T. I've manually changed the carrier to fit my SIM card (Settings>Connections>Mobile Networks>Network Operators>Search Now>AT&T). However, when I turn the phone off and on, it reverts back to T-Mobile. How can I get this to stay on AT&T by default?

Because your device was originally sold from T-Mobile it will unfortunately stay with T-Mobile bootup animation & bloatware unless you decide you want to learn to flash U1 firmware. Which this process can be learned by researching on sammobile.com. Good Luck!

In your APN settings you will have to set a new one for AT&T... This can be found by searching GSM APN settings for AT&T...
