There are currently three smart service packages to choose from, i.e., general package, update package, and subscription package
The content of the general service package includes cloud storage of various capacities, intelligent push, and monitor area (the differences among multiple general packages lie in the cloud storage capacity, and other smart features exhibit no difference in this aspect). 
After purchasing a non-professional (i.e., basic or advanced) service package, you can upgrade the basic and advanced versions by purchasing an update package.
There is no difference in content between the subscription service package and the general service package, except that subscription service packages are designed with an automatic subscription feature that requires no manual renewal.
