If a user hasn’t got this detail, he/she may send an SMS- “PROFILE” to the number 52244. BSNL will respond with an SMS that contains the profile details of the user and the validity extension amount details. The user will have to note this recharge amount now.

Suppose the recharge amount is 36 Rupees, refill your BSNL number with an amount more than 36 Rupees. For example, recharge it with 50 Rupees, so that there exists an amount greater than 36 Rupees in your account.

If you already have an amount greater than the required recharge amount in your account, then there is no need for this additional recharge.

Next step is to send the BSNL validity extension SMS. The SMS format is as follows-

Compared to the online recharge method or retailer recharge method, this one is pretty easy and can be done right from home! Please make use of this method to extend the validity of your BSNL prepaid number.
