Sinc the update yesterday I've had times where the phone doesn't read sim card or connect to Wifi. It's frustrating because I never had a problem with the phone until the update. It's only been a day and Ive had this problem 2 times where I have a useless phone for over an hour. Had to reboot many times to get it going again. Please TMobile and OnePlus fix this! Am I the only one having this problem?

I just updated mines this morning and having the same issue it wont read my SIM or connect to WIFI heck I even tried to manual enter my Wifi Address to find out it wont let you….Not sure if this is a TMobile update issue or Oneplus but I didnt spend money on a phone just so the manufacturer/service provider can brick it!

Just about all updates to Android 11 for any device by any OEM have had some major issues. Have you tried removing the SIM, cleaning it with a little Isopropyl, and then putting it back in? Sometimes the contacts start to get a little tarnished over time. There is an MSM Tool from OnePlus that can restore the devices firmware to an earlier build, if no troubleshooting solves the issue. If you can get the WiFi working, perhaps check for another update to see if there is an update to fix the issues you are having. Otherwise, using the MSM Toon will return your device to an earlier firmware while completely wiping the device.

I'm still having this issue on and off since the update. I've cleaned the sim card, what's strange is that the wifi gets affected also and it can't be turned on. No. You can download it directly fron the OnePlus support site, OnePlus Official forum, and XDA-Developers forum.

Anyone still struggling with this. I had no wifi calling, T-Mobile data just wasn't working and other connectivity issues. The last October 2022 security patch screwed with the SIM and phone functionality. Chances are this might be the same issue again. Go to T-Mobile and get a new SIM stat. Don't let them say it's cause your phone's not updated cause it's not your phone it's that update.

Send it out for warranty service, if it is still within the warranty period. You can contact OnePlus Support or use the insurance option, if that is something you pay for.

Yes, I have the same problem. SIM is not recognized one or two times per day. This only happens with Android 11 update.

Have you tried factory resetting your device? If there was an issue with WiFi Calling working on the 7T Pro McClaren Edition devices as well as connectivity issues. There would be a lot of posts about it in various communities and I would have had friends with those devices asking for help to get that issue fixed. Also, security updates don't actually touch or impact the modem firmware or radio interface layer at all.
