Short, quick post: I’d purchased a Nexus S recently, and once I got back to India, I had to re-activate my connection again.

Unlike the iPhone, however, my Android was unable to pick up the settings automatically & I had to enter them manually. To do this, head over to Settings -> Wireless & Networks -> Mobile Networks -> Access Point names. Tap on the options button -> New APN & enter the  settings as per your plan, as  mentioned in my previous post comparing various Airtel GPRS plans.

To recap:

Name: Enter a name to identify

APN/Address/Access point: for Airtel Mobile Office.

That’s it. Restart your phone(if required) and you should be able to start browsing.
