If I buy S10 unlocked from Samsung, can i use S7 SIM card?
I have been with AT&T for years and have a valid account (though my contract is now open).
My current S7 Edge was purchased through AT&T.
I want to purchase an unlocked S10+ from Samsung.
Can I order it not locked to AT&T, and plug in the SIM card that is in my S7 into the S10+ and still continue to use the S10 with my AT&T account?
Or is the SIM card tied to the S7 (IMEA #?) somehow? Will I lose AT&T calling or network features?
