• What is my Samsung Galaxy S21 Ultra 5G worth?

  The true value of an Samsung Galaxy S21 Ultra 5G depends on its condition and specifications like capacity and carrier. The most important factor will be the cosmetic and operational condition of your device. Of course, the better the condition the more money in your pocket, but the companies we search will even purchase broken devices!

  Phone values depreciate by around 40% over one year, but that rate jumps to 75% over three years. At the same time, values for old Samsung models drop by 15% or more after a new flagship is released. That means you should sell as soon as possible to get the most money for your used Samsung.

  Sending your phone to a Flipsy Trust Verified online buyback store is convenient since you’ll get a free printable shipping label and speed payments that are sent within 3 days of delivery. It's also worth mentioning that the buyback stores we search pay cash, not credit like carrier buyback programs which also offer 30% less comparatively.

• Can I sell my Samsung Galaxy S21 Ultra 5G near me?

  Yes, you can sell your Samsung Galaxy S21 Ultra 5G locally with Flipsy. Along with online options Flipsy shows you the best options to sell a Samsung near you.

  You could also list it on a marketplace like Craigslist or Facebook Marketplace, but be aware of several potential drawbacks which include:

  • No guarantee of sale
  • Fees can reduce profits (listing fees, selling fees, commissions, PayPal fees, etc.)
  • Time-consuming listings with phone details, photos, etc.
  • Sales can take a long time
  • Potential for scams

  • Lower payouts compared to other selling options
