MTNL is present in two cities only i.e. Delhi and Mumbai and in both these circles, the telecom operator provides awesome and cheap 3g plans. The best thing about MTNL 3G is that it can be used all over country even on roaming without additional fee. This is really very beneficial as no other operator in India provides unlimited 3g usage on any pack or plan, but MTNL does. Therefore, if customer can aquire MTNL Delhi or Mumbai sim card with help from local family members or relatives, the customer will be able to use 3g plans anywhere in country either in 3g dongle/usb datacard or in smartphone. It uses BSNL 3G network while on roaming to provide services. Also, recharge can be easily done online from anywhere. For example- there is 1650 unlimited 3g plan in which customer has to pay Rs.1650 for unlimited 3G data with validity of 30 days. This is indeed cheap and great for those heavy internet users.
Anyways, sticking to the topic, the USSD code for checking MTNL Dolphin 3G net balance is the same for Delhi as well as for Mumbai sim card.
- Just dial *446# and you’ll get available 3G data balance, remaining validity/expiry. It also shows you other benefits if available like free sms or talktime.
- To check mobile balance, dial *444# . This shows available talktime balance and validity of your sim card. After dialing this, you’ll also receive sms with available 3g net balance details.
- Other important code – *445# to know expiry of subscribed plans.
So, you can use either of the two ways to find details. I’ve personally tested these ussd codes and they work fine.
Note: 3G data plans and their benefits in both the circles may be different. (For example – At Rs.4500, you get 200 GB free 3G data with 6 months validity for MTNL Delhi SIM Card whereas you get 100GB 3g data with the same validity for Mumbai SIM Card.)
