Can you still use kik the app on iphone without getting charged?

I just got an iphone, and I was wondering. You know how you have to pay for texting? Well since I don't have unlimited, I have a certain limit. Will kik count you texting? Will you still be charged? Or not since it's a free app. If not is there an app that you can use on iphone for texting without being charged? And also, how do you know how many texts you sent? Will it alert you? Through email? Since I have a limit.

Kik is 100% free. It's not a texting app, more like a social networking app because you have to create a username and add people. If you want an actual texting app, there's textfree but it will give you a phone number for that app (won't change your actual phone number) but kik is great. All it requires it phone service. And it's fast

KIk is a totally free app that only use your Wi-Fi or data plan to operate. You don't get charged for sending or recieving SMS or MMS.

Although I would suggest that you try Whatsapp and viber. Pretty sure most people use this apps more than Kik

I'm getting charged for international texts from friends in Canada that shouldn't be happening if this social network is free what's the deal
