Why You’re Not Receiving OTP Messages

If you have previously opted out of promotional SMS, your network might also block system-generated OTPs. That’s why you must enable all incoming promotional messages to ensure timely delivery of OTPs and other verification codes.

Other Things to Check

  • Ensure your mobile number has not been ported to another network, which may affect message like OTP delivery. Use mobile which is not converted to another network

  • Ensure your mobile number is entered correctly.

  • Check if your SMS inbox is full — try deleting old messages.

  • Restart your phone after unblocking promotional messages.

  • Try inserting your SIM into another phone to test if the problem persists.
