Why SMS Issues Occur on BSNL
SMS issues on BSNL can stem from SIM-related problems, incorrect settings, network configurations, or account status. These issues affect both prepaid and postpaid users and can prevent sending texts, receiving OTPs, or accessing critical services. Below, we detail the causes and solutions for both sending and receiving SMS problems, ensuring you can resolve them quickly.
Unable to Send SMS on BSNL: Causes and Solutions
If you can’t send SMS from your BSNL SIM, here are the most common reasons and their solutions:
- New SIM Activation Delay:
- Cause: New BSNL SIMs, including those upgraded from 3G to 4G, replaced due to loss/theft, or ported via Mobile Number Portability (MNP), require up to 24 hours for SMS services to activate.
- Solution: Wait 24 hours after SIM activation. If the issue persists, contact BSNL customer care at 1800-180-1503 or 1503 (from BSNL numbers) or visit a BSNL service center.
- Incorrect SMS Center Number:
- Cause: An incorrect or outdated SMS Center (SMSC) number in your phone’s message settings can prevent SMS delivery.
- Solution: Verify and update the SMSC number based on your BSNL circle. Access your phone’s messaging app, navigate to Settings > Message Center Number, and enter the correct number from the table below. Restart your phone after updating.
- Inactive SMS Service:
- Cause: If you haven’t sent an SMS in the last 6 months, BSNL may deactivate outgoing SMS services to curb spam or inactive accounts.
- Solution: Call BSNL customer care (1800-180-1503) or visit a BSNL office to reactivate SMS services. For prepaid users, ensure your plan includes SMS benefits.
- Network Mode Issues:
- Cause: Incorrect network mode settings (e.g., Manual vs. Auto) or using 4G/LTE in areas with weak coverage can disrupt SMS functionality.
- Solution: Go to Settings > Network & Internet > Mobile Network. Switch between Manual and Auto modes, or change from 4G to 3G/2G. Restart your phone and try sending an SMS.
- Incorrect Date and Time:
- Cause: Incorrect device date and time can cause SMS authentication failures on BSNL’s network.
- Solution: Go to Settings > Date & Time, enable “Set Automatically,” and ensure your time zone is correct (IST for India). Restart your phone.
- Insufficient Balance or Plan Issue (Prepaid):
- Cause: Prepaid users may lack sufficient balance or an active plan with SMS benefits.
- Solution: Check your balance by dialing *123# or using the BSNL Selfcare app. Recharge with a plan that includes SMS (e.g., STV 147 offers 10 SMS/day). Verify plan validity.
- Device Compatibility:
- Cause: Older devices or those not supporting BSNL’s 4G bands may face SMS issues.
- Solution: Ensure your device supports BSNL’s 4G Band 1 (2100 MHz). Update your phone’s software or test the SIM in another compatible device.

Unable to Receive SMS on BSNL: Causes and Solutions
If you’re not receiving SMS, including OTPs, on your BSNL SIM, consider these reasons and solutions:
- New SIM Activation Delay:
- Cause: New or ported SIMs take up to 24 hours to activate incoming SMS services.
- Solution: Wait 24 hours. If OTPs or SMS are still not received, contact BSNL at 1800-180-1503.
- Do Not Disturb (DND) Activation:
- Cause: DND settings may block promotional or even transactional SMS (e.g., OTPs).
- Solution: Check DND status by texting “STOP” to 1909 or via the BSNL Selfcare app. Disable DND or allow transactional SMS by texting “START 0” to 1909.
- Full Message Storage:
- Cause: A full SMS inbox can prevent new messages from being received.
- Solution: Open your messaging app, delete old SMS (especially read OTPs), and ensure at least 20% storage is free. Restart your phone.
- Network Mode Issues:
- Cause: 4G/LTE networks in low-coverage areas may disrupt SMS reception.
- Solution: Switch to 3G or 2G (Settings > Network & Internet > Mobile Network). Restart your phone and check for incoming SMS.
- Incorrect Date and Time:
- Cause: Wrong device date/time can interfere with SMS authentication.
- Solution: Enable “Set Automatically” in Settings > Date & Time, set to IST, and restart your phone.
- Blocked or Blacklisted Number:
- Cause: Your number may be blocked by the recipient’s network or flagged for spam.
- Solution: Contact BSNL customer care to check your number’s status. Avoid sending bulk SMS to prevent blacklisting.
- SIM Card Issues:
- Cause: A damaged SIM or poor SIM tray contact can prevent SMS reception.
- Solution: Remove and reinsert the SIM, clean the SIM slot, or test in another phone. Replace the SIM at a BSNL center if needed (Rs. 50–100).
Tips for Optimizing BSNL SMS Services
