MySQL query to return rows which are not listed in another table

[nkolreshima1]

I have two tables in MySQL DB PHPMyAdmin:\[code\]Table-1: T1\[/code\]

\[code\]Table-2: T2\[/code\]

I need to write a mysql query which will return all IMEIs from \[code\]T1\[/code\] which are not listed in \[code\]T2\[/code\].For example, in this case query should return \[code\]123456781235176\[/code\].Thanks.
