Starter Clout - Phone number validation issue.

There is a bug in the phone number registration process, very minor, but would affect people selecting "Isle of Man" the validation forces use of numbers starting 1624.
However, 1624 is a landline in the Isle of Man.

The mobile prefix should start with a 7 (e.g. 7624) instead - i believe there are now some additional codes for IOM Mobiles now too - would need to check with the telecom provider there.

I suspect this is an issue with the service though?

No file, test, or entry point is named. Start by tracing the Isle of Man phone-number validation in the frontend and determine whether the rule is local or provided by an external service; verify the current mobile prefixes with the telecom provider before defining the fix and its validation checks.
