Why can’t the iPhone 6plus send text messages?

1. This situation must be caused by poor signal where you are standing.

2. You can go to Settings-Information-turn on the switch for sending text messages.

3. If there is a problem with your network, text messages will be sent through the operator.

4. iPhones send text messages through iMessage by default, even if they send text messages through the network by default.

5. This is sent through the network by turning on iMessage in Settings-Message-Open.

6. After it is closed, it is sent through the operator, that is, it is sent through the signal.
