Does Apple use money or traffic to send text messages?

If it is also an ios system or an Apple series product, using the iMessage that comes with the system requires no money, only traffic.

If it is a mobile phone such as Android or other functional machines, you need to charge the SMS fee according to the price set by the operator.

IMessage activation method:

1, so as to open Settings → Information →iMessage, and then it will show that it is waiting for activation.

2. After successful activation, you can see that the switch of iMesaage is on.

3. When the iMessage service is successfully activated, you can send iMessage information to your friends. However, there is also a prerequisite for sending iMessage, that is, the other party also uses iPhone and has also opened iMessage information service.

4. Find the Info icon on the iPhone home screen, and then click Open.

5. Select a friend who wants to send iMessage. The operation is the same as sending normal SMS. The iMessage message will be displayed in blue, and the word iMessage will appear in the SMS input box.

Here need to pay attention to the second step:

(1) Send a read receipt to let the other party see the time when we read the information.

② When iMessage is unavailable, it will be sent by SMS, which means that when there is no network or Apple's iMessage information service fails, the system will automatically send it by SMS.
