How to stop Flash SMS/Class 0 SMS in iphone jio esim?
Recently i not only used MNP (mobile number portability) to move from airtel to jio but also converted my regular sim to esim. And now, I have started getting Flash SMS that opens up with an alert sound and consumes the entire screen till i don't click on "Dismiss".
The content is never urgent but Ads by Jio to recharge my other number or some scheme. but always by jio. I have complained it to Jio but no use.
I find this extremely intrusive, drains my battery if gone unnoticed and to be honest feels like borderline illegal way of marketing. I would like to stop it from happening in my iphone.
p.s.: I have already tried the standard suggestions like other community conversations. Is it different somehow for esims or jio?
