Why cant my phone turn on its data?

[DJ REGGIE]

I just switched the sim card from my Samsung S3 to my Xperia XL. Calling and texing works fine on the Xperia but the data doesnt. I switched the sim card back to the S3 and found out that calling/texting and the data works fine. How do i fix this problem?

Are you sure your Xperia has the right settings for data access or that it's compatible with your network? You might need the configuration data from your carrier or, in some cases, you'd need them to 'activate' a different device on their systems for some features (data included) to work.
