It actually only raises a warning, advising to make sure the text of
such links makes clear what the target of the link is. Note that
mobileOK Basic only recognize http and https URIs, all the other schemes
are warned about, to help identify possible issues.

In this case, I think it's pretty clear this is a phone number.

tel: is the officially registered scheme:

I think wtai: used to be more widely supported (since it is the one that
was recommended by the WAP forum), but I don't know if this is still
true or not.
