1. Go to the APP Store to search for iVCam, and then make a purchase. For users who have installed the iVCam application, they can purchase it on the purchase page of the iVCam application through in-app purchase.
2. Buy a PC-side registration code on this site, where "one-year subscription" corresponds to "advanced annual fee" in the APP.
It should be noted that for domestic Android users, because they can't use Google Store for in-house purchase, they may have to download APK and purchase PC-side registration code to use it.
