True but I prefer to give SMS permissions to as few apps as possible. I turn off the SMS permission as soon as first time registration is done in bank/fintech apps
I have most banks apps and few UPI apps installed and they work just fine without SMS permission. The apps that don't start without the SMS permission in my phone are imobile and kiwi. And from the permission history logs, they seem to be accessing it atleast daily once which is more frequent than they need to...
Also to just get the payment reminders, you can just enter your phone number and last 4 cc digits to apps like paytm, phonepe, sbi unipay site .etc and they will remind you without needing sms permissions
