How to correctly create a table with mobile numbers of users?

Question

MySQL

I create a project on Laravel, created a users table, at first I wanted to put users' mobile numbers in it, but then I decided that there would be a huge number of users and each user might have more than one mobile number and decided to create a separate table in MySQL. How to properly implement this table?
