I bought a new T-mobile branded galaxy s21 ultra. This phone is awesome and working flawlessly with one exception. I took the T-mobile sim from my old phone, and put it in my new S21 ultra. In goigle messages, the chat feature will not verify my number even though I've had it for over 20 years. After reading on-line that this seems to be a wide spread issue. Since it won't verify my number, I cannot send or receive texts over wifi. My data has no issues, just over wifi. That is a major problem. Trying to reach out to Google was a nightmare, and T-mobile "so called expert" had no idea what I was trying to explain. ANYONE HAVE AN ANSWER? I've tried several things. No luck.
