Does it cost extra to use imessage?

[iMore Question]

Just wondering if there is a hidden cost with imessage.

 

[eyecrispy]

Nope.

Definitely not. I used it from the USA to my GF back in the UK and it didn't cost me a penny more than normal, especially if on a wifi, where it didn't cost me anything at all.

Data usage apply if not on wifi
