Your SIM played a tone issue
Hello All,
I am from India and using "Vi" (Vodafone Idea) as primary provider (postpaid) in my iPhone 12 pro max. For the past two days I started getting "(Primary)Your SIM played a tone " popup. I tried getting in to "SIM Applications" under Mobile Data. There is no such thing as "FLASH" or "Idea Flash" which can be deactivated. Did any one else face this issue.? This is very annoying.
