What is iMessage?

Discussion in 'iPhone' started by Chris Pisarra, Jan 11, 2012.

  1. So sometimes my text messages are in blue, indicating iMessage, I guess.

    What is it? Do I care? Does it make a difference to me in any way? Can I
    choose to use it instead of regular texting? Why would I? Or why wouldn't
    I?

    This seems like a distinction without a difference.

    If you have unlimited texting, it won't make a difference, but if you have
    limited texting or strictly pay per text, iMessage can save you money.

    It adds a bunch of features above and beyond traditional SMS (or
    even MMS) messaging.

    For one, the "address" which routes a message may be the
    cell-phone number, like traditional messages -- but it also
    may be any e-mail address you (or the recipient) has registered
    with Apple. That's how iMessage messages get to folks who
    have iPads and iPod Touch devices. You may register as many
    e-mail addresses as you like.

    iMessage messages travel over your internet connection (if
    you have 3G, it'll use that, if you have wifi, it'll use that).

    It's possible to have read-receipts in iMessage (not that I'm
    sure why anyone would actually use them).

    When you are typing, the recipient will see "..." showing them so.

    Messages are not limited to 140 chars.

    It's possible to have a multi-person chat.

    There are probably other things, but that's all I can think
    at the moment.

    Oh, and, of course, it's free - unlike SMS (which is one of
    the most astounding rip-offs I've ever seen - the phone
    companies have been making out like bandits on that).

    I don't have texting at all. It would cost an extra $10/month for
    the minimum amount of texting. But I can text my daughter who has
    an iPhone because iMessage doesn't use Verizon's texting. Her
    daughters want me to have conventional texting though.

    I can even use iMessage with my wi-fi iPad. My hope is that a
    universal app comes out that works with competitor's devices - causing
    the phone companies' texting model to die.

    Where do you register those email addresses?

    I have my main email address registered as my Apple ID, so I assume
    Apple would know about that. When I registered for iCloud I was also
    allocated a new email in the format , so perhaps that is
    another.

    If my iPhone is switched off and someone sends me an iMessage, would
    that be delivered to one of my email addresses? There more I delve
    into this iMessage stuff the more I realise how little I understand
    the mechanics of what is actually going on.

    They're automatically registered when you set up the account on the iPhone.

    No, you won't receive anything via email. Email addresses are just used
    as identifiers.

    Settings->Messages->Receive At

    You put in an e-mail address, Apple sends e-mail to that
    address to confirm, then it's activated.

    It should, but you can add any e-mail addresses you like.

    No. The e-mail address is just an identifier. As far as I
    know, the only time it's used by iMessage is the one time, when
    you register that e-mail address to link it to your account,
    to confirm it. After that, the address is just an identifier
    used to route iMessage messages to the Message app, not e-mail.

    If you send a txt via iMessage, it goes through Apple's iMessage network
    instead of your cell company's text message service. So it doesn't count
    against your text message allocation. (OF course, if you have unlimited
    texting, that doesn't matter.) If you're in an area where you have WiFi,
    but no cell signal, you can send an iMessage, but not a conventional text
    message.

    And therein lie the differences.

    How does my phone know who has an iPhone when I send them a message?
    If I send someone a text message for the first time somehow it gets
    switched to an iMessage. The same happens when someone sends me a
    message for the first time from another iPhone.

    Why do all these Apple devices have a small *i* in front of their name
    anyway? I remember the original iMac but am not sure of the
    significance of the small i. Is that supposed to signify *internet* ?

    When your phone is on, it registers tself to Apple as being "on". (This
    was one f the original innovations from Apple who provided a single push
    server so that all apps would go through the Apple server so there would
    be only one TCP link active to send notifications).

    So Apple knows about which of its phones are on at any point in time.

    You type in a phone number, it gets sent to Apple, Apple then responds
    with "yep, I can do that iMessage because the destination is on-line
    with me right now" or "sorry, you have to use SMS because that phone
    number isn't on right now.

    So every SMS message I send is accepted or rejected by the Apple
    servers first even before my carrier? And then people complain about
    Google invading privacy....

    Note quite the message. your iPhone verifies with Apple if the
    destination phone number is reacheable via iMessage or if it needs to
    use the carrier's SMS system. The message is then sent once to the
    appropriate system.

    Before you complain about invasion of privacy, bear in mind your
    cell phone carrier knows when your phone is turned on, and where
    it is. It has to so it can route incoming calls to your phone or to
    voicemail.

    If you want complete privacy on your cell phone, turn it off.

    iMessages are always free, SMS messages can be astonishingly expensive

    maybe even 50 cents each! oh no!

    if you think that is astonishingly expensive then you need a higher
    paying job or a better cellphone plan.

    anyone who uses sms more than occasionally should be on an texting plan
    and won't incur much expense at all (i.e. none if you pick unlimited).

    Apple may know which of its iPhone are switched on, but how does it
    associate a phone number with each of those devices?

    The telephone number is allocated to each phone operating on a network
    by the carrier whose SIM is in the phone. The phone itself can usually
    determine what number it is associated with, but this is not always
    the case.

    Via the AppleID. iMessages to my mobile number show up on my iphone, my
    ipad, my laptop, my MacPro, and my Mac mini.

    It is relevant. When you enter 800-555-1234 as SMS destination number,
    Apple has to check whether that phone is connected to the iMessage
    system at the moment.

    And this means that Apple's iMessage database has to contain the
    relationship between the phone and the phone number.

    Whether this relationship is established when you setup the iMessage on
    your phone once, or whether it is transmitted everytime your phone
    connects to iMessage, I do not know. But Apple can know and must know
    the relationship between your phone, your appleID and the phone number
    on your SIM card.
