Internet setting issue

[Neetu]

I am facing issue of "Configuration message could not be authenticated against your sim card. Message cannot be used to configure your phone".

Using Sony Xperia Tipo Dual Sim in India.

On clicking configuration setting sent by my operator, I get this message. I also tried to add APN Manually but that too didn't work. Called customer care of service provider many times, however there support team is clueless.

Please help.

You could try the automatic installation of the settings on the phone by going into menu > settings > xperia > internet settings.

Did you receive any error messages when trying to manually create the APN's?
