Make sure iPhone is Original not Fake
There are plenty of fake iPhones are avilale in the market. Sometime these iPhones are coming without any valid serial number. Sometime these makers are smart enough to sell iPhone with some fake serial number. Please collect the iPhone serial number from the seller and go to Apple website called Check Your Service and Support Coverage
If this online check correctly reports iPhone model and expected expiration of warranty, you can say the iPhone is a genuine one. Once you have iPhone in handy you can connect Apple store and try to download one free app from Apple store. If teh iPhone is original, then you will be able to download and run apps from the iTunes Store.
Make sure iPhone Compatibile with your Provider (Need iPhone Model number)
You have to make sure the phone is compatible to your service provider. Usually, iPhones are coming either GSM or CDMA or both in same model. Foe example in US, AT&T and T-Mobile is GSM and phones are compatible each other. These phones won’t work with Verizon or Sprint, both providers are CDMA.
You should know what type of phone you are going to buy and you can verify with iPhones’ model number. Once you have the iPhone model number (can get back case of phone or from iOS Settings > General > About > Model) there is an article Identify your iPhone model published by Apple that described technology used in each phone model.
Make sure iPhone is Career Unlocked (need IMEI)
Apple were selling two types of iPhone before, locked version and unlocked version. The are couple of choices to check the phone is career / SIM unlocked or not.
Test with a Different SIM: If you already have the phone with you, turn off the phone and replace the SIM with different carrer network. Turn back the phone and if the phone is unlocked one, you will be able to use the phone just like the other SIM.
Contact Original iPhone Service Provider: This is another worry free method. When you buy used iPhone you have to contact the current network provider with phone serial or IMEI number to make sure the phone is unlocked by the network provider.
Check with Online Tools: If you don’t have the freedom to do the above 2 methods, the last option is to depend an online tool like IMEI INFO (http://www.imei.info/) that display the iPhone status if you provide the IMEI / Serial number of the phone. We prefer this is as the last resort, because this online report may not be accurate always.
Check iPhone Warranty (need Serial / IMEI)
Apple offer one-year default warranty for Apple products. Sometimes buyers may purchase additional warranty for the peace of mind. You will be under the same protection if you can buy a used iPhone before the service warranty expire.
Please go to Apple Service Coverage Check link and verify the phone is under warranty with the serial number of the iPhone.
Make sure iPhone is Not Stolen or Activation Locked (need Serial / IMEI)
Apple introduced the Activation lock on iPhones to protect the device from theft. Before you pay the money for a used phone from any online store, you must get the IMEI or serial number to check the iPhone activation lock status. If you see activation lock enabled, you won’t be able to use that iPhone as your own.
Please contact iPhone seller and request to disable the activation lock and check again before you pay him. To disable the activation lock successfully, iPhone need original owner user ID and password.
Incase the iPhone you are planning to buy is stolen or seller is not the right owner, then he wont be able to disable the activation lock.
Alternatively, if you have iPhone in handy, you can check the activation lock on device itself, iPhone Settings > iCloud > Find My iPhone. This should have turned off before you pay money to seller. The owner need username and password to turn off this Find My iPhone settings.
This is all pretty much you can investigate with a Serial Number and IMEI number of the phone. Once you have phone in handy, you can go through the Complete Hardware Checklist Should Perform Before Buying Used iPhone for water / liquid damage and other hardware / sensor testing guidelines.
