Wenzhou's mobile phone number sent a text message to Taizhou's mobile phone, but it was not received.

There are two situations where you can't receive it. First, there is a system failure on the operator's side. Your message was sent, but the other party didn't receive it.

Second, your friend's mobile phone is set to reject SMS (some software can be installed on the mobile phone now), or the other party blacklists you. Hehe, then you can't get through.
