Hello @brendan-c and thank you for your PR! Can you please address my comment below?

Isn't prefixes for mobile phone numbers 9 and 6 instead of 8? The only source i can find is this wikipedia article

[brendan-c]

You could be correct. The information this was based on was from http://www.wtng.info/wtng-970-ps.html but it lists it's source as Paltel, which appears to no longer be a mobile carrier

[brendan-c]

I have made the changes requested to validator.js 079c113

And updated the tests f434556
