You could use parse ...

>> parse mea [ copy area 3 skip copy phone to "@" to end ]

>> phone
== "5551234"
This rule would be happy to parse anything with an "@" symbol and at
least 3 characters before it. If you want to check, if this is really a
mobile phone number, you can change it like this:
>> digit: charset [ #"0" - #"9" ]
== make bitset! #{
000000000000FF03000000000000000000000000000000000000000000000000
}
>> parse mea [ copy area2 3 digit copy phone2 6 8 digit "@" to end ]
== true
>> area2
== "416"
>> phone2
== "5551234"
Now you can be sure, that there are only digits before the "@" and at
least 3 for the area and 6 for the phone number, at most 8 for the phone
number.
I hope that helped,
Ingo
