I had been knocking my head from last two days looking for the GPRS setting for my new HTC OneV from BSNL. There is nothing on its portal, finally I had to reach the BSNL telephone exchange to get it and it seems they have that just now and is yet to be updated to their portal.
Here is how to set it up on your Android 4.0.3 device, for those who need it.
1. Tap on Settings to go to settings panel.
2. Tap Mobile network > Access Point Names.
3. On the APNs screen, tap Menu > New APN.
4. On the Edit access point screen, enter the APN settings. Tap an APN setting item to edit it.
For BSNL holders in East India the following setting will work which is BTW not available in the BSNL portal for HTC One V Android 4.0.3.
Name : BSNLNET
APN : bsnlnet
Proxy : not set
Port : not set
Username : not set
Password: not set
Server : not set
MMSC : not set
MMS proxy : not set
MMS port : not set
MCC : 404
MNC : 38
Authentication type : not set
APN type: default,hipri
APN enable/disable: APN enabled
Bearer : Unspecified
5. Tap Menu > Save.
And you are done happy browsing.
