I have h2o wireless that uses at&t. I'm a fan of smaller phones that can fit in my pocket and those ones are hard to find nowadays!
Next thing is to make sure you complete system updates, create or login in to your samsung account and get app updates. This s21 is just faster, better battery life, lasts me the whole day of using it.
No scratches or issues cosmetically. Only gripe i have is the fingerprint scanner can be a little wonky sometimes.
I wish i knew of this problem before i jumped through hoops to get this device. Now the inconvenience of having to return the phone and repackaging it to send it back.
Lo malo. Not unlocked. Chalk this one up to incompetence.
