Does texting someone with an iPhone use up data?

I recently purchased and iphone and someone told me that if I send a text from my iPhone to someone else with an iPhone, that it will use my data. Is this true? I have unlimited texting and 1gb data plan through AT&T.

Not necessarily. It actually sends it through iMessage, which is like an exclusive club for iPhone users.

Texting isn't data… You're fine

Texting does not use up your Internet data plan.

Don't know why the question of if texts using data is suddenly popping up. Texts never have & still don't require data/internet access on any phone.

Yes, Marissa,
But if you switch to Wi-Fi than its all free n your data won't be wasted or used.
