Hi Kumarasamy,

Please defer to asking these kind of questions on this platform as the kind of services provided is strictly academic and professional and is not associated to tasks that are alike to your topic of ask.

Nevertheless, since you have asked, you need to visit the operator office of your choice, i.e., the operator you want your future connection to be and then ask them to change your number to your choice and if that number is not previously occupied by some user then you might be allotted that number but still the chances of that are very slim to none.

BEST WISHES!
