1. Check the purchase time (activation state) to see if the production time and activation time are close, and the close is a brand new machine.

2. If the production time and activation time are reversed, it will be regarded as a replacement machine (after-sales replacement).

3. Except for the Bank of China, Hong Kong Bank, New Zealand, and Taiwan version, other versions are displayed as locked through online inquiries (reference only).

4. If the card shows that there is a signal and can be used, there is nothing or it has been unlocked (it is recommended not to upgrade at will for the locked version).

5. The equipment has expired, and if it is recently purchased, it is second-hand).

6. Correct understanding of the replacement machine: The replacement machine is a brand new machine, but the information of the equipment may be reversed.

7. There is 90 days of ** support from the day of activation, but some parallel imports will be activated in advance (except for the Bank of China, which are parallel imports).
