Hi! I updated my Carrier from AT&T Prepaid to AT&T Wireless (PostPaid) but I'm still using an unlocked S21 and I'm getting this error. Is it possible to update my registration as well. Or is it possible to at least withdraw me from the beta program if it's not possible.
I would like to withdraw from the One UI Beta Program on a phone that I did not enroll. I purchased it used/refurbished and the 'Settings > One UI Beta Program status ' returns the message that features aren't available because I have not joined or the country information has changed.
I'm having the same problem. I switched from AT&T to Mint. Please help!!
