How to solve: Cant Complete SMS verification and registration of UPI app (Google pay) due to Class 0 message popup

class 0 message popup

Class 0 message popup during SMS verification and couldn’t register app

When I was trying to set up my Google pay account on android pie device, I was facing a difficult problem. During configuring google pay, there is a step to find and verify the bank account linked to my mobile number. In that step, the app sends a cryptic SMS to a specified number. Soon after mobile send this message a “class 0 message” window popup, then the google pay registration fails and showing the following message.

Bank account couldn’t be added – please don’t switch from Google Pay while registration taking place.

I didn’t intentionally switch from Google Pay; I think it is due to the Class 0 message popup. I tried to block the class 0 message by stopping message notification, but it didn’t work. How to solve this issue and successfully register the app.

Block Class 0 message popup for success full SMS verification of app

The following trick is not actually blocking the Class 0 message, but it works perfectly for registration of google pay. In this trick, we change the default SMS app from default to another third-party app (here we chose Jio4GVoice).



1. Install any third party SMS application

2. Go to settings > Apps & notifications > Default app and tap on SMS app. Or you can directly search the SMS app on “Search in Settings” window
change default sms app

3. Change the default SMS app to newly installed SMS app (here Jio). This new app won’t allow Class 0 message popup.

4. Now you can continue your SMS verification of Google Pay without any hindrance.
