How many words can a 20M mobile phone QQ send?

You mean using QQ to send messages on your mobile phone. If you just use QQ, you can't use it. It's not the number of words. You open a web page and it consumes as much traffic as possible. Let me tell you about the conversion of this capacity unit. 1GB= 1024MB， 1MB= 1024KB， 1KB = 124 b。 1B is a byte, a number or English, and each symbol is a byte. A Chinese character is two bytes. 20mb =1024kb *1024b * 20 = 20971520 bytes. That is to say, a web page needs 1KB of traffic, so 20MB= 1024KB*20=20480KB, which means that such a website can be opened 20480 times. Okay, do you understand?
