If I'm on Wi-Fi, does it still charge for international messaging?
So I recently(July 24) just got the iPhone 5 (Verizon) and last night I got a text saying I already used 78% of my data allowance of my bill! Anyways, I honestly don't think that's possible because I most of the time I use my phone I'm on my Wi-Fi and supposedly it doesn't use up that much data on Wi-Fi? But also, if I text somebody that's located in the Uk (iPhone to iPhone, iMessaging only) will it still charge if I'm on Wi-Fi? Thanks! Verizon is getting me really mad with the data usage!
