Salaxy S4 doesn't recognize SIM in India. Voice calls work but data doesn't. (The SIM was working with data plan). Any idea?

There is a message that says something like "Unrecognised SIM" but the Voice works. Data just doesn't work.

You have to change the APN to match the carrier settings in that region.
