NRIs face OTP delays with Indian mobile numbers

NRIs often rely on Indian mobile numbers for banking services, including OTP-based authentication.

Improper management of Indian mobile numbers abroad can lead to OTP delays and service interruptions.

Failure to maintain SIM activity may result in deactivation by telecom providers, blocking banking access.

To avoid issues, NRIs should ensure the SIM is used periodically or enabled for international roaming.
