subtype 'WirelessNumber', as 'Str', where { /^\d{10}$/ or /^\d{2}$/ };
coerce 'WirelessNumber', from 'Str', via { s/-//g; $_ };
Alternately,
subtype 'DashyWirelessNumber', as 'Str', where { /^\d{3}-\d{3}-\d{4}$/ };
coerce 'WirelessNumber', from 'DashyWirelessNumber', via { s/-//g; $_ };
BTW, "I tried X but it didn't work" doesn't tell us very much, especially when
X is a whole category of possible approaches. If you're more specific it's
easier to help you.
hdp.
