The number 2147483647 is the biggest ten-digit positive integer that can be stored in a 4 byte integer field.

You should use a larger field type like BIGINT although for this particular case I recommend VARCHAR. It's a phone number not an actual integer you need to do math with.

P.S: You should really use pepared statements to protect your application from threats like SQL Injection. And you should always hash the password before inserting it in the database.
