How to charge MMS for sending SMS? How to calculate?

The mobile phone you mentioned should rarely be used to send messages to Sina Weibo. It's usually a short message package. Short messages with less than 70 words count as two, and 70- 140 words count as two. And so on. If you want to surf the Internet on your mobile phone, you must first turn on the GPRS function, which is free. If this function is not turned on, you cannot receive MMS at the same time. Mobile Internet access can package traffic. Generally, you can set up an online chat package (for example, Suzhou area: 20 yuan contains 200 short messages, 50M traffic, color ring back tone function fee, etc.). If your mobile phone is out of service, you can make any call you want. If it is stopped, there will be a voice prompt: Sorry, your phone is stopped. You can also dial 10086, press the voice prompt and select "0" for manual service.
