OnePlus 7T Pro Mclaren Andoid 11 uodate sim oroblems
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...
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.
