Hello everyone, I have been having this problem on my iphone which is connected to an airtel SIM. Everytime i go to link my UPI with my bank account, i need to send a message. However after sending a message, i get a flash message about how much balance i have which disrupts the verification. I have tried everything to stop these flash messages including turning on DND and every other internet hack. What should i do? Will switching to postpaid help? or do i need another SIM, perhaps Jio? or do they also send flash messages?.
The only place i was able to connect my bank account with an UPI was the airtel app however i can't do it on paytm. Because of this problem i can't connect with YONO either.
