Why did the mobile phone disconnect after receiving the text message?

Under normal circumstances, SMS takes up the operator's signal, but now 4G+ mobile phones are not like this.

Solutions to bad mobile phone network;

Step 1: First, determine whether the wireless signal in the current area of the mobile phone is bad, such as the corner, which is too far away from the router.

Step two. Sometimes it may be that the network settings of the mobile phone's own system are a bit confusing, resulting in poor signal when connecting to the wireless. At this time, you can try to restore the mobile phone network settings and see if you can solve the problem.
