One phone, two numbers! With the Samsung Galaxy S21 Dual Sim, you can split work from pleasure, share your phone, or live that secret agent double life you've always dreamed of. We've got you covered with Samsung S21 refurbished models to save you a packet.

How do I use dual SIM on S21 5G?

The Samsung S21 Dual Sim was launched in 2021, as part of the Samsung Galaxy S21 family. It's a genuinely great phone with features that rival the Apple iPhone 12 and cameras that even hold their own against the iPhone 12 Pro Max. Shoot 1080p video at up to 120 fps, 4K at up to 60 fps, and 8K at 24 fps for incredible quality or seriously super slo-mo. Want to switch sims? With two nano sims back-to-back in the ultra-compact card tray, you can receive calls and messages on both numbers. Give each sim card a custom name and a different coloured icon, and you'll never have that awkward moment of answering the wrong line. Better yet, when you make a call or send a text message, tap the SIM card icon and choose which number to send from.

Is refurbished better than used?

It all starts with a detailed inspection by our in-house experts. Every Galaxy handset must pass every step of a 100-point checklist before it gets the green tick. Fail at any stage, and we'll carefully recycle it instead. We give every phone a condition rating and a price to match. Choose As New or Pristine for handsets closest to factory condition, or Excellent and Good for even bigger savings on cost.
