I’m unable to complete login or registration on the YONO SBI app because the OTP is not arriving on my mobile number.
Can someone explain the common reasons behind OTP delivery failure such as network issues, SIM problems, DND settings, or device restrictions and the best steps to fix it?
When attempting to log in, register, or reset your MPIN on the SBI YONO app, if the OTP (One-Time Password) is not appearing, there is typically a problem with the device, SIM, network, or SMS routing.
Fortunately, the majority of OTP issues can be resolved in a matter of minutes at home.
