2026 年第一季是電信業者的續約旺季，也是各大企業舉辦尾牙春酒的高峰期。許多人因此拿到最新的 iPhone 17 系列或 Samsung Galaxy S25 Ultra。如果您本身不需要這支新手機，或者更傾向於將其兌換成現金來靈活運用，「如何賣出最高價」就成為了一門學問。Used3C.net 提醒您，全新機的處理方式與二手機截然不同，一個小動作可能就會影響數千元的收購價。想知道目前全新機的市場行情？請查詢 全新手機收購價格表。
The first quarter of 2026 is the peak season for telecom contract renewals and also the high season for major corporate year-end parties and spring banquets. Many people end up with the latest iPhone 17 series or Samsung Galaxy S25 Ultra. If you don’t need this new phone yourself, or prefer to convert it into cash for flexible use, “how to sell for the highest price” becomes a crucial skill. Used3C.net reminds you that handling a brand-new phone is completely different from a used one; a small action could affect the buyback price by thousands of dollars.

關鍵守則：絕對不要拆封 (Do Not Open)
無論是續約取得或是尾牙抽中，若您打算出售 iPhone 17 或 S25 Ultra，最重要的黃金準則是：「絕對不要拆封」。在收購市場中，「全新未拆封（New In Box）」與「已拆封新品（Open Box）」的價格有著顯著落差。一旦外盒膠膜破損或封條被割開，即便手機完全沒使用過，也會被視為二手機處理，價格可能瞬間跌落 10% 至 20%。因此，拿到手機後請妥善保存，避免擠壓或受潮。
Whether obtained through a contract renewal or a lucky draw, if you plan to sell the iPhone 17 or S25 Ultra, the most important golden rule is: “Do Not Open”. In the buyback market, there is a significant price gap between “New In Box” and “Open Box”. Once the outer plastic film is damaged or the seal is cut, even if the phone has never been used, it will be treated as a second-hand phone, and the price may instantly drop by 10% to 20%. Therefore, please store the phone properly after receiving it to avoid crushing or moisture.
續約 S25 Ultra 與 Pixel 10 的最佳脫手期
相較於 iPhone 17 的價格相對穩定，Samsung S25 Ultra 或 Pixel 10 等 Android 旗艦機的價格波動較大。通常在上市後的前三個月內，收購價格最好。若您是為了「洗機換現金」而辦理續約，強烈建議在拿到手機的當天或當週內就前往青蘋果3C 門市進行交易。隨著市場貨源增加，收購價格會每週下修，猶豫越久，您能拿到的現金就越少。
Compared to the relatively stable price of the iPhone 17, the prices of Android flagships like the Samsung S25 Ultra or Pixel 10 fluctuate more. Usually, the buyback prices are best within the first three months of launch. If you renewed your contract specifically to “cash out the phone,” it is strongly recommended to visit a Green Apple 3C store to trade on the day or within the week you receive the phone. As market supply increases, buyback prices will be revised downward weekly; the longer you hesitate, the less cash you will get.
實體門市收購：保障您的個資與金流
出售高單價的全新未拆封手機，網路上充斥著詐騙風險（例如買家調包、聲稱內容物不符等）。選擇青蘋果3C 的實體門市（台中、台南、高雄），我們會在您面前確認盒裝封條的完整性，並核對您的身分證件（確保商品來源合法，非贓物）。確認無誤後，立即以現金全額支付。這不僅保障了買賣雙方，也能讓您快速、安心地拿到資金。
When selling high-value brand new sealed phones, the internet is full of fraud risks (such as buyers swapping items or claiming contents do not match). Choosing Green Apple 3C’s physical stores (Taichung, Tainan, Kaohsiung), we will verify the integrity of the box seals in front of you and check your ID (to ensure the source of the goods is legal and not stolen). Once confirmed, we pay the full amount in cash immediately. This not only protects both parties but also allows you to get funds quickly and securely.
