What to check when buying and selling new and used phones

When buying or selling a phone, the two key points are the paperwork and the device’s condition. Use an invoice or a contract, finish checking the device before the sale and wipe your data before selling. You can also get an offer from Telefon Sat, our company’s device buying site.

Cep Market Repair TeamIn Kadıköy since 2006
Key points
  • Buy and sell with an invoice or a contract with ID; it protects you from later problems.
  • When buying used, check the screen, battery, cameras, charging and Parts and Service History.
  • Before selling, back up, sign out of your accounts and reset the phone.
  • Faulty phones and phones with a cracked screen can also be sold; the price depends on the condition.
  • Cep Market, Teknoway and Telefon Sat are the same company; you can get an offer for your device from Telefon Sat.

01What to check when buying

  1. Paperwork. Ask for an invoice for a new phone and a sales contract with ID for a used one.
  2. Accounts. The Apple ID on iPhone or the Google account on Android must be signed out.
  3. Screen and touch. Check solid colours for spots, lines or dead areas.
  4. Battery. Check battery health and that it charges.
  5. Parts history. On iPhone, check Parts and Service History.

02What to do when selling

  • Back up. Back up your photos and contacts.
  • Sign out. On iPhone, sign out of your Apple ID and turn off Find My; on Android, sign out of your Google account and turn off Find My Device.
  • Reset. Restore factory settings and remove the SIM and memory card.
  • Ask for paperwork. Sell with a contract and ID.

03Where can you sell your phone?

Cep Market, Teknoway and Telefon Sat are the same company. If you want to sell your device, choose your model on our device buying site Telefon Sat and get an offer.

FAQ

Frequently asked questions

01

Can a faulty phone or one with a cracked screen be sold?

Yes. The price depends on the model and its condition.

02

Is resetting the phone enough before selling?

First sign out of the account (Apple ID on iPhone, Google account on Android), then reset. A phone still linked to an account cannot be used by its new owner.

03

Should I have a used phone checked before buying?

It is not required but recommended. Diagnosis is free.

04

What documents do I need to sell a phone?

Have your ID and, if you have it, the invoice ready; we recommend selling with a contract and ID.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
