Facebook mobile texts - simplicity 15 o2?

[kitty]

I'm on simplicity 15 with O2 (NYSE: TEF) - £14.69 a month (i think!) for 300 minutes, 600 texts and unlimited calls and texts to o2.
Will it cost me to use this service or will it use my free texts?
Thanks x

It's free but if you text a lot it might put you over your limit. I have unlimited text and data so I'm safe. They don't really send me a whole lot of texts and you can choose who and what to receive texts/updates from. There really aren't that many carriers on there though. I'm with a small company that just has local coverage for pretty much all of Wisconsin and most of Michigan's Upper Peninsula. Surprisingly, though, I can use Facebook mobile. Oops, I'm ranting. Sorry. :/
