Why can't Apple get all the text messages when its mobile phone is turned off?

First, we need to unlock the phone, then find the settings in the phone screen, and then we click Enter. After going in, we set up the interface, find the SMS option, and then we click in. Then, we slid the phone down and saw a message filtering strangers, so we chose to turn it off.

Check whether the mailbox is full, if so, please delete some information; If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware; Check whether it is intercepted by mobile phone interception software; Check whether the cell phone signal is normal and try to test whether it can be received elsewhere.

Open the settings, as shown. Find the information, as shown. Open iMessage information, as shown in the figure. Click Settings, as shown. Just open the cellular data, as shown in the figure.

Of course, mobile phone downtime will lead to SMS failure, as long as it is recharged in time. Mobile phone storage is full. If the storage space of iPhone is full, you will not receive SMS. It is recommended to delete unnecessary text messages or other contents that occupy memory before trying to receive text messages.
