Are questions regarding telephone networks or SMS networks considered on-topic?
I have two (real) examples:
How do we find out the "sending" date and time of an SMS?
When we receive an SMS, the date and time of receipt is shown. This means that if someone sends me an SMS while my phone is switched off, the date and time of the SMS receipt will reflect the time when I switch on the phone.
How do we find out the estimated actual date and time when the SMS was sent (the time when the SMSC had received the message)? Is it even possible?
How do we tell when an SMS we sent expires?
If we send an SMS to a friend, the message may expire and be deleted in the SMSC.
How do we know when the message we sent expires and never reach its intended destination?
