Can't send text/SMS through Pidgin's AIM?

[Ant]

Hello.

In Trillian in Windows, I can send texts/SMS through its AIM with with 
United States (U.S.) mobile phone numbers like +12345678901. However, 
Debian stable's Pidgin v2.10.9 says I can't send since my contact isn't 
on? Why not? Searches show it is not possible through AIM or am I wrong?

Thank you in advance. :)

mention a good human being." --Norbert Wiener
