    How much data will iMessage use? Will it use as much data as BBM if you were to put them beside eachother? I currently don't use a data plan for my iPhone 4 but seeing as iMessage has features I want, I am willing to switch to a data plan.

    Excluding pictures, videos, and audio. Its very little. Probably only a few KB per message or about as much as an average push notification.

    It'll be free if you have a data plan

    How do you have an iPhone without a data plan?

    Thanks for the reply guys!

    I had a Blackberry 9700 before, and I decided I wanted an iPhone, so I went to Apple and bought it full price.

    Thats not his question. He wants to know how much data it uses so that he can, I assume, choose what data plan he wants.

    Are you on AT&T? I thought that they just add a data plan automatically to smartphone users since they can tell some how what phone you use and its a required charge for smart phone users.

    I would say from 1-10kb for normal txt, pics would be the size of the pic plus a few kbs more

    I'm on Rogers in Canada, so I guess I'm lucky :).
    Is that the size of a normal SMS? I actually don't know =.= .

    Ahhh...I'm not quite sure on my conversions. Someone feel free to correct me if I'm wrong

    But a character in ASCII is 1 byte (8 bits)

    Basically, that means take the length of your message in characters (including spaces), and that is the number of bytes your message will be. 1000 of those in a kb, 1,000,000 in a mb, and 1,000,000,000 in a gb

    So on a 250mb plan on AT&T, you can send 250 million characters through iMessage (or really send and receive) without going over, assuming you don't use any other data (which you will)

    1 Byte = 8 bits
    1 KB = 2^10 B, or 1024 Bytes
    1 MB = 2^10 KB, or 1024 KB, or 1048576 Bytes

    A stand 160 character SMS is around 140 bytes. You can send around 7,500 SMS messages with an average 160 character length with just 1MB of data.

    In short, the amount of data use for your average texter will be un-noticable.

    Photos and videos would be interesting to see some data though. I know when you send a photo via e-mail it asks if you want to resize and it shows you the filesizes as options. There doesn't appear to be that option when iMessaging, so does Apple just choose a size for you? If not, then the original could be quite large. If so, what size do they choose? I had a friend iMessage me from his iPhone 4 and then saved the file to my Photo Albums and it's 1.76MB 2592x1936!

    Apple needs to provide an option to "not use 3G for data", and in those cases I would be happy with it uses 1 of my 200 SMS messages instead.
