October 23 is the arrival date for opening-minute orders and the day stores start selling, not a promise for a new order.

$19.99/month · $199.99/year · $399 one-time

Monthly plan for 12 months: 12 x $19.99 = $239.88
Yearly plan: $199.99
Two years on the yearly plan: 2 x $199.99 = $399.98
One-time price: $399.00
One inner-display repair
without AppleCare+: $999
with AppleCare+: $99 -> $900 difference
The cover layer that hides the crease can be
replaced by Apple or an authorized provider
($49 without / $19 with AppleCare+). It is not
a user-applied screen protector.
Check the one-time plan's coverage term on
Apple's US store before comparing it with the
yearly plan.|
Mainland activation models listed by Apple: A3518, A3635, A3715, A3718, A3721. Confirm yours with the carrier.
|
|
Supporting mainland carriers: China Mobile, China Telecom, China Unicom; setup includes an in-store identity check.
|
|
Apple's mainland support guide says overseas-purchased models cannot install mainland carrier eSIM profiles.
|
|
Roaming with a Hong Kong number is not the same as activating a mainland number.
|
|
Returns differ: the mainland policy describes 14 calendar days for eligible returns; Hong Kong online orders have no ordinary change-of-mind returns.
|
|
HKD and RMB prices can't be subtracted: convert both with the same dated rate first.
