Recently, it was very tough to get the mobile internet settings from India’s largest cellular service provider. This link on their website to receive settings via SMS never worked despite several retries on different days.
Finally, he called their helpline at 121 and got to the option where they ask all sorts of questions including those about handset model before sending the Mobile Internet settings. Took over 10-15 minutes since it was difficult to know which option had the handset.
The same activity can be done manually as follows, in under a minute.
Select Settings -> More... -> Mobile Networks -> Access Point Names and press on the + button to add an Access Point
- In Name, enter
Airtel Internet, in APN, enter
- Save the APN and activate Mobile Data to cross-check it works.
