IM+ for samsung galaxy Ace 2 + is it free to run without being billed on phone?

[AuraTodd]

Hi I hope this is the right forum. Got IM+ running in the background on my Samsung. Can you tell me if its free to run?

I am with Talk Talk 15 mobile, and I am worried that i might be charged a huge bill for running it. I am aloud 300-400 mega bytes of internet.

If it does charge, how do i sign out as it keeps switching my WiFi on? Thanks.

most the apps runs on data or wifi connection. i dont think im+ will have a high data usage but id exit the app when not in use

How do I exit it and sign off please?
