I tunes could not check for an update error 1630

Hello all
Just the other day I was trying to check for an update for my iPad but when I opened iTunes to check for an update, it won't check and instead resulted in the following error.
The screenshot of the error is attached below:

The message states:
ITunes could not check for an update to the carrier settings for your iPad. An unknown error occurred (1630)
Can anyone now please tell me why is this happening and what should I do next?
What is wrong with my device? Any help in this regard will be appreciated.
Waiting for your replies
Regards
