Enable SMS
Make sure the NC Mobile line is not silenced / blocking unknowns. Some bank apps need a voice-capable number — Standard/Pro fit better.

Bank OTP tips
Use Lite/Standard with SMS enabled. Try the 3-day risk-free window if a bank rejects the number.
Lite risk-free
In the first 3 days, if an institution rejects the number for valid OTP → request a refund via Support with proof (screenshot of the error — never include the OTP code).
Security
Never share OTP codes. NC Mobile Support will never ask for your OTP.
