Limited texting and imessage?

Okay so i have an iphone. And i have limited texting. Only 100 a month. Does that still apply to imessage? In other words, if i text friends that have an iphone and have imessage, does it still count in the 100 texts?

IMessages do not count as texts UNLESS it does not go thru and then the settings will send it as a text. If you go into settings you can turn it off (send as text automatically) and then it would sit there if it did not go thru. Even if its turned off, you can then send as a text message if it did not go thru later by tapping the message.
