Suppose the number of words in each short message is about 20, one Chinese character equals 2B, and 20 words equals 40B. . The unit conversion is 1g = 1000m, 1m = 1000m, 1k = 1000m. . It means that 1K can store 25 messages, 1M can store 25,000 messages, 1G can store 25 million messages and 13G can store 325 million messages. . . . Of course, this is assuming that you don't download applications, music and memory. . The landlord can refer to it. .
