Would you buy a 512 GB S21 Ultra in 2023?
I got one unlocked, same storage size for 500 back in 2022. Seems too pricey, keep looking. It's a great phone though, can't go wrong. More on reddit.com

November 27, 2022S21 Ultra 256 GB or S23 Ultra 512 GB (see price difference)
The S21u at $550 is still very worth it but the S23u for that price is unreal. I'd go with that for the two extra years of software support alone.

March 25, 2021How much of a credit did you get for your S21 Ultra 5G?
You're saying a 4 year old $1200 MSRP phone that has dropped to about $250-300 for a refurbished model and $400-500 new is not worth an $800 trade in? More on reddit.com

February 6, 2025Does anyone know where to buy an S21 Ultra with 512gb?
I bought mine refurbished on Ebay. Had it for about 1.5 months so far, and still very happy with it. I did about 3-4 months off-on searching, trying to decide amazon vs ebay, but ultimately found a reputable seller on ebay. More on reddit.com

November 27, 2022 -
I've been looking for a S21U to use as a secondary device. I found one for $699 on ebay in excellent condition but I feel like that's expensive for a phone released in 2021. What are your thoughts?
P.S. this is my 1st post so apologies if I did something wrong 😅

A wee bit pricey when renewed ones are cheaper and have a years warranty and a 30-day return policy. https://www.backmarket.com/en-us/p/samsung-galaxy-s21-ultra-5g-256-gb-black-unlocked/8322653a-f2b7-44cf-a74c-6336bcec9f43

So forgive me if it's been asked. Probably a lot of times. But I'm very unfamiliar with the S series as I have used the Note and the Fold 3.
I can get a used but mint condition S21 Ultra 256 GB 12 RAM with box and accessories and s pen included all for $550 Canadian. Alternatively, I can get the S23 Ultra 512 GB 12 GB RAM sealed for $850 Canadian.
Which is the better deal? Would appreciate any help.
Thank you.
