I have had my new S21 Ultra for a month now. Since I got it I have not been able to receive calls over standalone 5G as I found in my own troubleshooting no thanks to T-Force. I have been in contact with 8, yes, 8 reps 2...YES, TWO tickets have been filed both marked as resolved.........still not working. FOR THE LOVE OF GOD SOMEONE FIX MY $1.3k phone I'm fed up. Yes I have rebooted many times, yes I have tried a new sim card, yes I have reset network settings more times than I can count (very inconvenient btw) I am left with no other option but to leave T-Mobile if this is not resolved ASAP. It's too bad too, I've only been a customer for 3 months.
