Hi,
Runing a Galaxy S21 Ultra T-Mobile (SM-G998U)
My phone pulled down the latest T-Mobile update yesterday around 10am EST time Installed it. Since then I have lost all data connectivity unless using Wi-Fi, texting and phone calls are fine.
I tried the troubleshooting below:
Restart
Power off/Power On
Pulled the sim card (while off and On
Changing the network modes to LTE/3g and LTE/3G/2G
Manually creating an APN with IPV4/IPV6
Manually Selecting Networking operators (also tried AT&T then back to T-Mobile)
Did some errands in other towns to confirm it is not a tower problem other phone in the house does have 4g/5g full signal. My phone does have full bars as well just missing the 4G/5G symbol.
