How many short messages can a 5m data stream be used for flying letters?

Fetion's mobile phone client sends short messages for free, but it will generate traffic upstairs, so it will generate traffic charges. I suggest you do a monthly traffic package. 5M can send about 250,000 bytes, which is almost 250,000 words. I think if you send more text messages, it is enough to set a monthly traffic in 5 yuan, and the monthly traffic in 5 yuan is 10M. ! Traffic is only sent out, and collection will not generate traffic!
