What should I do if my Battle.net Pass is set with SMS verification, but I can't receive SMS?

The reason for this problem is that if there is a problem with the mobile phone network, the problem can be solved by restoring the network. Taking Apple's mobile phone as an example, the method to restore the network is as follows:

1. First open the Settings button, find and click the "General" option, as shown in the figure below, and then go to the next step.

2. Secondly, after completing the above steps, drop down to find and click the recovery option, as shown in the figure below, and then enter the next step.

3. Then, after completing the above steps, find the third option: restore network settings, click this option, as shown in the figure below, and then go to the next step.

4. Then, after completing the above steps, a window will pop up at the bottom of the page, click the "Restore network settings" option, as shown in the figure below, and then go to the next step.

5. Finally, after completing the above steps, the network signal will return to normal after the phone is turned off and restarted, as shown in the following figure. In this way, the problem is solved.
