SMS is Apple's native function. There are two ways for iPhone to send information, one is short messages from traditional operators, and the other is free information from iMessage. The following is the solution to the failure of sending SMS by iPhone7.

1. Regarding the failure of sending by iMessage, first of all, of course, it is necessary to confirm whether the current mobile network signal of iPhone is normal. In some signal blind areas, such as elevators and toilets, it is normal to send text messages.

2. If it is confirmed that there is no problem with the iPhone signal and the call is normal, then you can try to restart the phone at this time, press and hold the power button of the phone, slide it down and then turn it on.

3. If you still can't send SMS after restarting, you can try to restore the network settings of iPhone. Settings-General-Restore list can be solved by restoring network settings.

4. If it still doesn't work after restoring the network settings, it is recommended to call the operator's customer service and ask them to check the data in the background of the mobile phone to see if there is any problem.
