Halfway through the news, the mobile phone was dead. Can the other party receive the message?

When you see the message starting to be sent, it's actually just the phone and the carrier server "shaking hands". Handshake succeeded, and the transmission was very fast.

If the power is cut off during the handshake, it means that no SMS was sent this time.

If the handshake is unsuccessful, the record is not sent; If the handshake is successful and the transmission is interrupted at the beginning, there will be a transmission record, but nothing will be sent.

If the transmission has started, then the other party will receive some information.

Then there is a check signal. If it is broken at this time, it will basically not affect the reception of the final information.
