No Sim Signal

[Saurav_7]

My both sim are of same operator. Today suddenly my 2nd Sim got no singal for 10 min. Tried Aeroplane mode. But I forgot making anything right on ROG phone is a big mistake. I didn't got any sim detection after aeroplane mode. Removed sim tray and inserted again but still getting no signal. 

Now ROG phones having trouble with doing the work that even a feature phone can do. 

For more info I'm using this sim for more than 5-6 years on the same location. Here we have 4G and 5G connectivity too.

I have Vodafone Idea - Vi India Prepaid SIM that keeps getting corrupted in 1-2 days when in ROG 7 Ultimate phone. Says no sim card or Unknown Carrier. Cannot activate in sim card settings. Once corrupted, it won't work in other 5G phones too. 
I already replaced physical sim card at sim store twice. Same issue was seen in 1-2 days.
Issue started with recent update. Was perfect till few weeks ago.
The SIM doesn't get corrupted if it's not in ROG 7 Ultimate. Tested for 3-4 days on a different phone.

Found a temporary fix though, if I put it in a 2G phone for few mins and back in the phone, it gets fixed for a day or two.
