1. Back up data on old iPhones
Before receiving a new device, users should back up their current iPhone to iCloud or computer. This is an important step to avoid losing photos, contacts, messages and application data when switching to a new device.
If the iCloud capacity is not enough, users can check and clear unnecessary data or use other backup methods.
2. Check Apple Account
Users need to remember the login information of the Apple Account being used on the old iPhone. This is the account used to sync data, download applications and access Apple services.
Before selling or transferring old devices, you need to log out of your account from the device and turn off the Find My feature according to the correct procedure.
3. Check the SIM usage method
New iPhones may have different SIMs depending on the version and market. For devices using eSIM, users should check the network operator's support in advance and prepare a plan to switch numbers to eSIM.
Preparing in advance will help avoid the situation of having received the phone but not being able to activate the phone number to make calls, text messages or use mobile data.
4. Check the order before receiving the machine
Users should check the model, color, memory capacity and registered order information. In particular, it is necessary to pay attention to the 256GB, 512GB, 1TB or 2TB versions, because the selling price between configurations varies quite a lot.
If placing the machine through a dealer, buyers should also save the deposit information, expected selling price and accompanying policies for comparison when receiving goods.
5. When receiving the machine, check the appearance first
After receiving a new iPhone 18, users should carefully check the box, body, screen, camera cluster and locations that are prone to scratches or dentures.
Next, check the serial/IMEI number on the machine and compare it with the information on the box, invoice or purchase voucher.
6. Check the machine before leaving the store
Buyers can check the screen, camera, speakers, microphone, buttons, Wi-Fi connection, Bluetooth, charger and SIM/eSIM recognition capability.
If buying directly at the store, you should spend time checking the basic functions on the spot instead of just bringing the machine home and then discovering the problem.
