Apple 6 mobile phone, can't send group messages, how to set it back?

1, because the network signal is not very good, resulting in network delay! However, when using the mobile phone, exit the interface and re-enter it, showing that it has actually been sent. In this case, please press the sensing button on the right side of Home. Just re-enter it!

At the same time, check whether the SMS can be sent and whether the flight mode is turned on. Just open it again!

2. It is caused by using mobile phone management software. Generally, there will be a startup prohibition item in mobile phone management software. After entering this software, check whether SMS is also banned. If it is banned, just change it and restart the phone.

If you can't solve it, you can try to restore the factory settings, but remember to back up the data on your mobile phone with backup software!

3. The SMS function is turned off. This situation can be solved by a phone call and manual service!
