Internet Connection Problem WHILE USING SIM CARD BUT IT WORKS WITH WIFI SONY XPERIA TIPO

[1D11]

I HAD XPERIA TIPO DUAL  PHONE AND MY SIM CARD IS OF BHARAT SANCHAR NIGAM LIMITED, i.e. CELLONE INDIA PREPAID SIM CARD IN INDIA THERE ARE FOUR ZONES  I.E. EAST, WEST,SOUTH AND NORTH.  WHILE DOWNLOADING THE INTERNET SETTING  ON PHONE IT SHOWS SELECT OPERATOR  CELLONE SOUTH AND EAST ONLY AND NOT THE WEST AND NORTH  I AM LIVING IN INDIA'S WEST SIDE  SO I WANT TO SELCT OPERATOR CELLONE WEST BUT THERE IS NO OPTION OF CELLONE WEST.  

WHETHER IT IS A PROBLEM OF SOFTWARE OF SONY MOBILE OR THE OPERATOR CELLONE.

The problem could be on any side, but to solve your problem, just try contacting your customer care to get manual settings for your location. Then enter them at Settings--more--Mobile networks--Access Point Names--tap menu--New APN. Or you can try searching the internet for the settings.
