That's not how it works. Your aadhar account is linked to one number. Why do you need to link all your numbers to your aadhar?

Besides the link is not two way. Case in point - a friend forgot to recharge their phone. The phone went out of service. Another person got the phone and started getting my friend's aadhar otps. Even though they got the phone using their own aadhar number. The "link your phone to aadhar when you need a new connection" has got nothing to do with "link your aadhar number to your phone in order to get authentication OTPs".

They are two entirely different processes.
