IMessage use data? How much?

Ok so I just got an iPhone 5c and I'm a little confused now. I heard that you can basically only use iMessage to text other iPhone, iPod ect. Users. But then I heard that using iMessage uses data. I have 4 GB and I'm just wondering if I text kind of a lot using iMessage if it would kill my data? Obviously I'm not really good with this kind of stuff so any info you have to help me would be great

How does H20 wireless work(read details)?

I'm getting an unlocked iPhone 5 with a sim card slot and I want H20 because I get unlimited calls and text but i don't know how much I would have to pay… I want to know how much I would have to pay for data, unlimited calls and unlimited text, and for just unlimited calls and unlimited text. I need to know because my cousin has H20 just unlimited calls and unlimited text but he claims to pay 30$. I know someone who pays 60$ for H20 but i don't know what he uses. Also I know this might sound like a stupid question but is it paid monthly?

MIGHT HAVE BEEN SCAMED. LIVE IN SOUTH AFRICA?

I saw a phone on OLX advertised for R3500 and I phoned the guy and he sounded very proffesional, answered all my questions gave me the website so I could check the item I wanted to buy and gave me the address of his shops (apparently situated in "PE and "Johannesburg"), and I very gulable did a bank transfer, so a week later I still hadnt got the phone and he said he doesn't have stock of the iphone 16 Gig I must pay an extra R1000 to get the 25 Gig ( I have not payed the extra R1000) . He is now not replying to emails and when i phone him he pretends to be someone else… What do you guys suggest I do, I live in South Africa, … I will go to the police but they seem very occupied with more serious cases… How do you catch a criminal like this? Any ideas what I could do? If you can help me in any way please send me an email so we can chat… Thank you ( I know it was a stupid move)

Candy Crush progress deleted?

Candy crush would not let me spin the mystery prize wheel, telling me "Facebook log in expired." I entered my Facebook info only to have all progress deleted, back to level one. Guessing I was never logged in through 430+ levels of crushing? I logged out of FB and still on level one. Devastated. Was playing on iPhone.
