Is it true that Unicom Card 9 yuan package 300M package?

Hello, the charges for mobile phone packages in different provinces and cities will be slightly different, because all provinces and cities will introduce local package charges. Does Unicom have a mobile phone package with 300M traffic in 9 yuan? I suggest you first ask the seller where the mobile phone card belongs, and then consult the Unicom customer service hotline where the mobile phone card belongs. If there is, you should buy it again. If not, I suggest you don't buy it easily to avoid the situation that the mobile phone card you bought is different from the package fee you understand.
