Guangdong Guangzhou Unicom Wanzhongka

I suggest you call the customer service of Guangzhou Unicom to check your detailed phone bill and see if there is a minimum consumption package. If it is the minimum consumption package, you will also be charged the phone bill in 30 yuan if you spend less than 30 yuan. I suggest you call to find out. Then the mobile phone displays the "3G" network, because your mobile phone supports 3G networks. If you don't surf the internet, there will be no deduction.
