BSNL OTP Not Received? Fixes for BSNL SIM Cards

If OTPs are not reaching your BSNL number, check signal and plan validity, look in spam, and restart the phone. In weak coverage, try outdoors.

Why BSNL users miss codes

• Weak or no network signal indoors or in rural areas.
• Plan or validity has run out, limiting services.
• Text inbox is full.
• The app sending the OTP has a delay or outage.
• The number on the app account is wrong.

Fixes to try

1. Look at the signal bars; move outdoors or near a window if they are low.
2. Turn airplane mode on for 10 seconds, then off.
3. Check plan validity in the BSNL Selfcare app or by your usual balance check.
4. Delete old messages if storage is full.
5. Open the spam and blocked folders in your Messages app.

4G and network mode

BSNL has been rolling out 4G in many circles. If your phone is set to a network mode that does not suit what is available, it may drop signal often. In mobile network settings, try the automatic mode, and make sure the BSNL SIM is the one selected for SMS.

DND settings

Blocking promotional messages through DND should not stop OTPs, because OTPs are sent as transactional messages. If you suspect a block, check your DND preferences with BSNL.

Codes from apps

Getting help from BSNL

If no messages arrive from any service for a day, contact BSNL customer care through the Selfcare app or a customer service centre. Take ID if a SIM replacement is needed; an old SIM card may need swapping for a 4G one.

Do not share OTPs

Callers claiming your BSNL SIM will be blocked unless you share an OTP or complete "KYC" over the phone are scammers. See spotting fake verification texts.
