I want to buy an Apple 4s mobile phone, I don't know the store. If I don't go to the store, I'm afraid to buy a fake one. Can you tell me something about it? ...

Then you should go to those big mobile phone stores and buy an Apple mobile phone. When you buy it, you should ask if there are any licensed products. If the salesperson says yes, you will generally be guaranteed to pay 10% for the fake. Apple phones are unopened. The mobile phone store unsealed the activation for you on the spot, and obtained the seller's guarantee to issue the purchase evaluation certificate. You can immediately go to after-sales monitoring to find out whether you have bought the real goods. Under normal circumstances, as long as you buy a large regular mobile phone shop, you can guarantee the authenticity.
