Asynchronous and synchronous transmission

Smslib
There are two ways to send text messages.

1.
Synchronous sending: when your app uses smslib
When a text message is sent, the app thread will be locked until the text message is sent or fails to be sent.

2.
Asynchronous sending: when you use this method to send a text message, the app
The thread will not be locked, smsliib
Will return immediately, smslib will send your text message (s) in the background. You can choose whether to remind you of the status of the text message.

 

Callback Function

Inbound voice cballs:When a call is received, you can set whether to remind you. Please note that the call will automatically and unconditionally stop

Inbound messages:Whenever a new text message comes,Smlib
You can set to call your specified method.
