Currently, you can purchase 6TB and 12TB iCloud+ plans through the iCloud+ interface as premium alternatives to the existing 50GB, 200GB, and 2TB storage plans.

It's known that the 6TB iCloud+ plan is priced at 749,000đ per month and users will need to pay 1,499,000đ per month for the 12TB plan. Previously, an individual iCloud account would provide a maximum storage capacity of 2TB at a cost of 249,000đ per month in Vietnam.
Apple suggests that the 6TB plan is ideal for photographers and content creators, while the 12TB option targets 'advanced users'. Apple's new 6TB and 12TB plans can be shared among family members, allowing multiple individuals to benefit from increased storage capacity at a reasonable cost.

For those unaware, iCloud+ offers several benefits including Private Relay for browsing Safari privately, Hide My Email for generating one-time email addresses for each website, HomeKit Secure Video for storing HomeKit camera footage, and support for custom email domains that can be used with iCloud email addresses.
