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...
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.
