How does Apple 6 activate SMS?

The reason why Apple 6plus always fails to activate iMessage may be that there is something wrong with the settings. The proposed solution includes the following steps:

1. As shown in the figure below, when iMessage is activated successfully, you can see that it has been opened in the Settings-Information list.

2. Sometimes activating iMessage will encounter the problem that it cannot be activated. In general, you can try to activate it several times first.

3. If it still doesn't work, please turn off the iPhone, then turn it on again and then activate it.

4. If the problem cannot be solved after restarting, you can try to turn off the wireless network and activate the iMessage information service directly with the mobile phone network. You can directly open the control center, click turn off wireless, and then try to activate.

5. If activation through wireless network or mobile network is unsuccessful, you can also try to restore the network settings of iPhone at this time. In Settings-General-Restore, you can choose to restore the network settings, as shown in the figure.

6. After the recovery is successful, reconnect the network and see if the iMessage service can be successfully activated. If it still doesn't work, the suggestion given at this time is to activate the iMessage service another time.
