The mobile phone prompts to turn off the phone and send a message, but the message received reports that the other party has received it, which helps the respondent to give an accurate answer.

Under normal circumstances, if you turn off your phone and send him a message, you won't be prompted to send it successfully.

And when he receives your message after turning it on, your mobile phone will prompt that it was sent successfully.

I'm referring to the short message receipt here, not the prompt from your mobile phone saying success. )

I used to track someone's mobile phone in this way ~ just send a text message ~ as soon as he turned it on, I would receive a text message saying that the other party had successfully received it.

So I know he's sexually aroused ~

And you said to call her to turn it off, but the SMS receipt prompted success ~ generally there are the following situations.

First, her mobile phone is a smart phone, which can install an incoming call firewall. You are not on her white list ~ but your friend only turned on the incoming call firewall, but didn't turn on SMS interception, so your phone can't get in ~ but SMS can be sent ~ which I tried personally ~

The second is that she transferred the incoming call from her mobile phone to another mobile phone that was turned off ~ in this case, the mobile phone can't get in ~ but the short message can still be received ~

Third, it's hard to say ~ Your mobile phone is different from ours ~ Maybe he also said that he received the message when his mobile phone was turned off ~ But personally, this is impossible ~
