I have Oneplus 8T with Android 13.
My SIM was on Slot 2 yesterday. Then I accidentally clicked on "Disable SIM".
Now it says "No eSIM" "Disable eSIM to u.." (it only shows second line partially) when I insert it in Slot 2.
When I insert it in Slot 1, it says "No SIM card detected".
If I use any other SIM, it works on either slots.
When I this SIM on other android phones or even a feature phone, it works correctly without any issue whatsoever.
I've already tried the "Reset Network Settings" feature. Ideally I don't want to reset my phone completely
