State-owned telecom operator BSNL has defined USSD codes which help subscribers in checking their data balance, SMS balance, talk time information and much more. If you are a BSNL user, you can use these USSD codes to keep a tab on your balance of different services. Alternatively, you can also check your balance through the official app of the telco or by making a call as well. Before using USSD codes, you should know that these codes are toll-free and with them, you get instant updates on the balance. However, these USSD codes are only applicable for BSNL users residing in India.
BSNL Balance Check
There are multiple ways through which you can check your BSNL balance. Open your calling app and dial *123# to get information regarding the main balance of your account. You can also dial *124*1# to know the main balance. Users can further download the My BSNL app to keep track of the main balance.
