Hi there,

hope you are doing fine.

If you have mistakenly filled the wrong mobile number in the wbjee counselling you need to immediately contact the counselling authorities and do the needful required to change your mobile number as it might face you a difficulty in getting the admission in college further.

You can contact the help section and register your complaint in the wbjee counselling section by visiting their official website and registering the issue.

Also, you need to contact the individuals related to it and those who know about the counselling related issues so that they van help you in correcting the mobile  number and resolving your issue.

You can go the faqs section of the counselling and then take the knowledge about the issue if there persist any.

Hope this resolves your query.
