If I live in the USA and text someon from Canada will it cost?

I live in the US and have a friend from Canada… My phone is the iphone 5S and I use AT&T… I have unlimited texting so if I text my friend from Canada will it still be extra money?

This isn't a question to ask in the Canadian section, it is about your cell phone plan and carrier. Unlimited texting in the US, NOT Canada. It is $.25 to $.50 per message.

International call International Plan. YOU check YOUR plan.
