Here is an article that will be useful for BSNL (Bharat Sanchar Nigam Limited) users from Madhya Pradesh State in India. In this article, I have provided a chart. The chart contains all the necessary USSD codes that a BSNL user would need. Using the USSD codes mentioned in this article, BSNL users from Madhya Pradesh circle could check their 3G data plan balance and validity, main account balance and validity, activate new 3G data pack, check and activate night plan packs etc.
Please note that the above USSD codes work well in Madhya Pradesh circle. Share this information so that more and more BSNL users may make use of these codes.
