Mobile phones send short messages that others can't receive.

1. Did he blacklist you and refuse to receive text messages?

Maybe he didn't like your mobile phone number, so he blocked your message. Maybe it's because there are some unlucky numbers in your number, or it's related to people he doesn't like or sad past events ~ ~

You just need to check his cell phone to know this ~ ~

2, or his mobile phone is in arrears ~ ~

You can't receive text messages if you owe more than one day. Maybe he hasn't found out ... it's relatively unlikely. ...

In this case, you can know by calling directly ~ ~ You can also set the SMS to send a report, that is, when did the other party receive it after the SMS was sent ~ ~ If the other party's number is down or does not exist, a report will usually come back soon ~ ~ If it is said that sending failed for a long time, there are many other reasons ~ ~

3. Another possibility is that his cell phone signal is too poor ~

Under normal circumstances, this amount will still be received, and it will take a long time to say that the delivery was successful ~ ~ Of course, there are times when it is unsuccessful, and it will take a long time to show that the delivery failed ~

4, it is also possible that he is teasing you, thinking that your mobile phone is too broken, or deliberately saying that you didn't receive the text message ~

You can see if he has received the amount reported before ~ ~ If he has, he is lying ~ ~ But I don't know if your mobile phone is broken ... I personally advocate frugality. If it still works, don't lose it! ! ! O(∩_∩)O~

~O(∩_∩)O~ I wish you find the reason as soon as possible ~ ~ Call in case of emergency in the future, so as not to delay ~~O(∩_∩)O~
