Voice-Based BSNL Balance Inquiry
Some users prefer calling instead of using apps or codes. BSNL provides toll-free numbers for balance check via IVR.
Dial 1503 or 1800-180-1503 from your BSNL number. Follow the voice instructions and select the correct option to hear your balance.
This method is useful for elderly users or those not comfortable with mobile apps or USSD codes.
What to Do If the BSNL Balance Check Code Doesn’t Work
Sometimes, due to network issues or technical errors, the USSD code might not respond. In that case:
Wait for a few minutes and try again.
Restart your phone and redial the code.
Make sure you are using a BSNL SIM card, not another provider.
If the problem continues, contact BSNL customer care or visit the nearest BSNL center.
Why Keeping Track of Balance Is Important
If you don’t check your balance often, you might end up with a zero balance during emergency calls or while browsing. Using the BSNL balance check code ensures you’re always ready. You can also track your usage pattern and recharge accordingly.
