Never mind I solved the problem. I had to replace 'INT' with 'BIGINT' forgot 10 digit mobile numbers require 8 bytes.
IMO, and that of most modellers I suspect, the use of a numeric type to represent a non-numeric phone number is the problem. While phone numbers typically consist of digits they are not numbers - they are identifiers. In particular, it makes no sense to perform math operations on them. I'd suggest you use "text" for the data type - add a check constraint if you want to ensure the imported data meets specific criteria.
