How much do you charge for mobile phone traffic? Thank you. Be specific.

GPRS traffic billing-a headache! ! Don't you think? 1. About the rate: The theoretical transmission rate of GPRS is 17 1.2Kbps, which is more than 20 KB per second. However, in the process of using Xiaocao, the maximum download speed is 32Kbps, which is almost the same as that of fixed-line dial-up internet access, while during the day, the internet access speed is greatly reduced. I believe many GPRS users have deeply realized the meaning of the word "theory". 2. About the price: the flow is deducted from the receipt and delivery. China Mobile has launched four kinds of GPRS tariff packages, all of which are free: no monthly fee, 0.03 yuan per 1024 bytes = 5 12 Chinese characters; Economic package: the monthly fee is 20 yuan, and you can enjoy 1MB free traffic every month, and the excess is charged at 0.0 1 yuan /KB; Fashion package: monthly fee 100 yuan, and you can enjoy 20MB of free traffic every month. The excess is charged at 0.0 1 yuan /KB; Business package: 200 yuan monthly fee, unlimited traffic. There seems to be a saying that 500 yuan is capped, and there is no distinction between the flow inside and outside the province. The preferential period is from 23: 00 every day to 7:00 the next day, and the charged traffic during the preferential period is 50% of the actual traffic. 3. About settlement: the company issued the settlement rules around 10 in 2006: the province to which it belongs will settle the account to the roaming province. 00 1/KB 4。 If you want to download a 5MB MP3 song, the person who handles the free package will have to pay 150 yuan. Text: 1kB= 1024 bytes (Byte)=5 12 Chinese characters =7 ordinary short messages (70 words) Voice: 0.6kb= 1 sec 5 seconds =3kb=9 minutes 10 sentence 5. About MMS MMS allows mobile phone users to send short messages with pictures. Because of the large amount of data, there are special requirements for bandwidth. It is best to open GPRS service. The current fee is as follows: sender: 3 cents per article, but no GPRS traffic fee; The receiver only charges GPRS traffic fee. For MMS, both the sender and the receiver have to pay, but in the past short message experience, spam messages are often received, but in the short message era, the receiver does not charge. MMS: In this case, the party receiving spam will also charge. Is this reasonable? In addition, the biggest selling point of MMS is that the mobile phone with digital camera function takes photos and sends them to friends in time. Of course, when MMS is flying all over the sky, the problem of portrait right may be inevitable in the future.
