On the use of mobile phone short messages

ET SMS pinch is the kind of dialog box that sends text messages? , according to the sender (the other party)

It's not like digging that kind of software Oh, no need for network traffic or anything.

It is equivalent to a software for sending and receiving short messages. Every time I receive a text message, I will be prompted.

Directly opening the SMS will open in this software, which is equivalent to using the information that comes with it.

Generally, the opportunity will start automatically, but what software is running in the background generally does not exist (it appears as soon as the text message comes)

-? -I don't know why

And it can't receive MMS, just text.
