My mobile sends SMS to random numbers without my permission. All messages are sent automatically. Here is an example of an SMS.

SBIUPI qUrXgeX26iEY%2B2si9JHhubIjm7R2aHoo6pWcbXBpJho%3D

All the receivers are Indian numbers (mostly airtel sim card). When I check the Truecaller app I found those numbers are named Cybercrime Frauds and reported as spam by more than 18000 peoples.

I have checked my app SMS permissions and checked for hidden apps. I couldn't find anything harmful.

Is there anything to afraid?

    Do you know for sure that these messages are actually being sent from your phone - as opposed to being sent from some other device and spoofed to make it look like they were sent from your number?

    I am not sure that those messages are sent from the phone. But my message app shows that I have sent. I am using stock android mobile and google messages. Apr 27, 2020 at 5:49

I think you have "SBI UPI" The State Bank of India (SBI) Unified Payments Interface (UPI) app on the phone which is sending your payment card info via SMS.


I also had been afraid of this and complained. It's just a verification message from your side. If you are using paytm, every time you verify your phone number it'll send a key (like the one you mentioned) from your phone to paytm, for verifying. I am not sure why people reported those numbers as spam. But I think it's nothing to worry about.

  • if you have a reference for paytm software sending confirmation codes via sms it would finish this answer off nicely
