I only received half the text messages.

This may be caused by the following two reasons:

1, the operator's network problem or the operator's own server problem, the operator's network signal is not very strong, this will happen. You can try it in a place with strong signal.

2. If the performance of the mobile phone is used for a long time, it will also affect the network, resulting in only half of the information received. Under normal circumstances, the content of the short message will not be lost, and you can check it later.
