Under what circumstances can't the other party's mobile phone receive SMS?

Generally, as long as you send it there, you will definitely receive it one by one and explain it to you.

1 The other party's battery is low (it will be turned off when it is collected), and it will be collected when it is charged and turned on.

2 Turn it off and then on, and the other party still receives it.

The other battery was received after being plugged in separately from the mobile phone.

4 the other party takes off the mobile phone card or inserts the card in the same sentence.

The other party can't receive the signal after the signal is weak or good.

6 The other party has set relevant settings (such as anti-interference function). As long as this exception is turned on, it will not be received.

It's no use if the other party's mobile phone or mobile phone card is damaged. If it's broken, you can't see it. If it's fixed, you can still see it.

I can't see the other party's mobile phone due to the interference of the external environment, but I can still receive it as long as it is in good condition.

9 the other party is not in the service area and there is no signal.

10 The other party's mobile phone is in arrears, and you can't get it. Your mobile phone shows a sending error.

1 1 Other reasons may depend on the specific situation.

One more thing, your mobile phone must have an expiration date for sending short messages. You just need to change it to the minimum value, such as 1 day. If the other party's phone is turned off, there is no power, and there is no signal interference for more than one day, your mobile phone will automatically cancel sending the short message after a delay of one day, indicating that it cannot be sent.
