Question

Someone's phone being dead affecting SMS delivered time

by wherebouts1372 / April 29, 2011 2:26 AM PDT

This is my understanding:
If someone's phone is off/dead than if you send them an SMS, it will not be delivered until they turn their phone back on. So it's safe to assume that if the sent and delivered times you see on your phone in the message you sent are the same, that their phone received the message when you sent it. Is this corrrect? And does anyone know if this is true for all phones/service providers?

Nice question.

But since SMS is not a sure thing, it's possible for such to get lost forever. And here on just a few phones from one network to the next I've seen messages arrive with a time before it was sent as well as long delays of 10 or more minutes.

What I'm getting at here is a question. Were you thinking that this was reliable?

In reply to: Nice question.

You bring up a good point about in not being a sure thing. But here's what we're looking at: They DID receive the messages but not until they supposedly plugged their phone in to charge. Which from what I've read about how SMS messages work, it will continue to try to send the messages for a certain period of time so it makes sense they would receive them once they phone turned on. We tested with someone else and found that if they turned their phone off and we sent a text message, the delivered time would not show until they turned it back on and the message was delivered (makes sense). And the send/delivery times showed the 4 minutes between sending the message (sent time) and them turning their phone back on and actually receiving it (delivered time).

More than likely your suspicions are correct, but...

...going by what Bob said, are you expecting this technology to be ample proof a la CSI(?)
