Hello Student

AtThe time of NEET UG form fill up your mobile number included in the application form then it will be not a problem for you to  show your mobile number is valid as it has been registered or included in your form fill up of NEET UG. As  earlier you have registered your mobile number in the website of MCC then in any way it may not be invalid mobile number. Even There is any problem you have to submit a request letter to the authority of medical counselling committee for to remove the problem you are facing regarding your mobile number registering.

Hope this will help.
