Replying to Most secure way to communicate with cellphone?

so obviously the worst way is by talking on the cellphone.

next worst i think is texting, its harder but pigs can scoop that up pretty easily too i believe.

i think emails are pretty safe, especially cause you can make as many email addresses as you want,

is their any impervious route for communication? I heard blackbwer toerry messenger was incripted or something that made it imposible to intercept or something.

anybody know the answer to this?
