步驟一：備份重要資料 (Backup Your Data)

無論是 iOS 的 iCloud 還是 Android 的 Google 雲端硬碟，賣手機前的第一步絕對是備份。照片、聯絡人與 LINE 對話紀錄一旦重置就無法救回，請務必確認雲端備份已完成。

Whether it’s iCloud for iOS or Google Drive for Android, the first step before selling your phone is absolutely backing up. Photos, contacts, and LINE chat histories cannot be recovered once reset, so please ensure your cloud backup is complete.

步驟二：登出 Apple ID 或 Google 帳號 (Sign Out of Accounts)

這是最常被忽略的一步。如果沒有登出 Apple ID 並關閉「尋找我的 iPhone」，下一位使用者將無法啟用手機，這會導致店家無法收購或大幅扣減回收金額。

This is the most commonly overlooked step. If you do not sign out of your Apple ID and turn off “Find My iPhone,” the next user will be unable to activate the phone, which will cause stores to be unable to buy it back or significantly reduce the buyback amount.

步驟三：還原原廠設定 (Factory Reset)

為了確保沒有任何殘留檔案，請進入設定執行「清除所有內容與設定」。這能將手機恢復到剛出廠的狀態，保障您的隱私安全。

To ensure no files remain, please go to settings and execute “Erase All Content and Settings.” This restores the phone to its factory state, safeguarding your privacy.

步驟四：準備盒裝與配件 (Prepare Box and Accessories)

雖然單機也能販售，但附上原廠盒裝與充電線通常能獲得更好的估價。若您擁有原廠保固卡或購買證明，也建議一併攜帶。

Although the phone can be sold alone, including the original box and charging cable usually results in a better valuation. If you have the original warranty card or proof of purchase, it is recommended to bring them along as well.

步驟五：慎選實體門市交易 (Choose Physical Stores)

網路上充斥著個人買賣的詐騙風險，為了交易安全，建議選擇有實體店面的收購商。特別是居住在台中、台南或高雄的朋友，選擇在地經營多年的店家，不僅能現場檢測，還能立即拿到現金，省去寄送的風險。

The internet is full of fraud risks in individual trading. For transaction safety, it is recommended to choose a buyback merchant with a physical store. Especially for friends living in Taichung, Tainan, or Kaohsiung, choosing a shop that has been operating locally for years allows for on-site inspection and immediate cash payment, saving the risk of shipping.
