I received a text message that the 3G data package will be automatically upgraded to a 4G data package because the original 3G data package has been offline. The telecommunications company upgrades the 4G data package for all old users of the 3G data package. For example, the original 3G data package is The upgraded 4G traffic package of 20 yuan for 150M will be 20 yuan for 300M. Starting from next month, you will enjoy more traffic at the same price. This upgrade is free and will not have any impact except the name change of the monthly traffic package.
