Mtnl 3g Recharge And Validity

Can anyone tell me the USSD to check the validity of the data plan. Can see the data remaining but not showing that till when it is valid.
Also, what's the amount to recharge for 500mb 3g 1 month? Is it Rs 99 as on the mtnl website or has it changed? For Delhi circle, can I recharge online other than paytm as its giving error for 3g recharge.

*444# Will show you your validity on screen and you will recieve an SMS instantly showing your data balance. I st6ill have no idea how to find out how long the data balance is valid for. I guess calling 444 is the only way.
Here is a list of useful USSD's for MTNL.

444 from mobile and follow the instructions.
*444# from your mobile to check account balance and validity.
*445# to know the expiry of plan vouchers.
*446# from your mobile to know the balance and expiry of free promotions(minutes, sms, data)
