If you are using a 2G connection, you will have to recharge with a Re. 1.00 Voucher for migration from 2G to 3G, your prepaid balance will be carried forward but you will get a Zero Validity & immediately opt for one of the Voice / Data Plans with BSNL. For more details:
3G Home Page
The choose to recharge with an activation voucher of Rs. 120.00 & you will get Rs. 150.00 talktime with 30 days validity and then topup with a Rs. 330.00 voucher & you will get a 1 GB Data Limit.
Topup later with similar voucher of Rs. 330.00 (inclusive of Service Tax) for another 1 GB Data limit with Zero Validity. You will have to recharge with a Validity Voucher to further use this limit. Regarding the Service Tax on the Validity Extension Voucher, BSNL Customer Service is itself not clear. The Website says you have to pay & the Customer Care says you don't. But I think you need to follow the website.
One thing. Every single session of usage rounds off your billed usage to the next MB. Say you used 1.30 MB in a session, then 2.00 MB will be deducted from your Account.
Dial *123*6# to know the amount of Data Limit left to your Account.
You will get speeds of approx 35 KB/s or 280 kbps.
I am using it and its working great on my
Nokia N73 connected to PC. Please feel free to post any queries.
Enjoy,
