What's the difference between sending a flying letter with a mobile phone and sending a text message?

1. If you are online, please reply to the computer.

2. If you are offline, you can automatically reply to your mobile phone without deleting 12520. If you are online, you need to delete it.

3. If there is a monthly subscription to SMS, it will be included in the monthly subscription; If there is no SMS, the charge is 0. 1 yuan/article.

4. When the mobile phone sends Fetion, you can download a Fetion software and package GPRS traffic, which can save 0. 1 yuan/message, but you need to charge the traffic fee. Generally, it is enough to subscribe to 5 yuan every month.

5. At present, except the old machine, as soon as the machine comes out, it can fly as long as it is a mobile phone. Of course, the old machine must be downloadable. But in the form of SMS, you don't need to download it, and any mobile phone can do this.
