    I forgot my iPhone at work on Friday. It's still there.

    But I can still do SMS via Message on my Mac.

    Does that mean, since the iPhone is connected to the WiFi at work, that
    messages are flowing to/from the iPhone via the internet which then does
    the SMS traffic?

    More specifically via iCloud?

    I don't have a "smart" phone. I use email. Pretty much every vendor
    has an SMS-Email gateway. You can google it. Works just fine on the
    few occasions when I need it.

  3. It's kinda crappy looking, but I find Heywire useful if I'm without a
    cell. It can TXT from the web, Mac and Windows desktop apps, and iOS or
    Android apps, to most US carriers (it's how I stay in touch with some US
    friends who don't have iPhones or only have a dumb cell), and a bunch of
    other countries.

    Are you sure that the message went out via SMS, and via iMessage? More
    specifically, was/is the address/name of the recipient shown in blue
    (iMessage) or green (SMS) in Messages on the iPhone?

    If it went out via iMessage, no iPhone involvement is needed anyway.
    iMessage (like WhatsApp, Facebook Messenger, ...) transmits directly via
    the internet. Only SMS (text messages) uses (AFAIK mandatorily) the
    mobile phone network, and there the part used for voice telephony, not
    the one used to give you internet access.

    Since the addressee has an Android, there is no way it could be "blue".
    And of course it was green.

    No, the way it works is:
    <copy from prior post on Mac group - <naughty JR>>

    My Mac -> Apple (Xing international border; cc: CSIS, NSA)
    Apple -> my iPhone (Xing international border; cc: NSA, CSIS)
    my iPhone (SMS) -> my cellco.
    my cellco -> his cellco.
    his cellco -> his android.

    Reverse all that for messages coming the other way.

    iMessage is encrypted, and as far as I know, the SMS sent from or to your
    Mac is using the same old encryption.

    1. Your Mac -> Encrypt -> iCloud
    2. iCloud -> iPhone -> Decrypt
    3. Send to cell company (unencrypted)

    On both of these steps the message is encrypted.
    No encryption here.

    Did it again! (And it's in the iPhone NG that it was truncated)....
