I wish Samsung had kept the ability for me to add my own SD card.
So from the description, these are basically lightly used customer returned phones?
This is why I haven’t let go of my Note 20 Ultra.
I guess you can add an Esim which I’d never heard of but I’m pretty sure it’s just a cloud sim card. Maybe someone can elaborate on that… 
I just got one of these last week from Amazon, totally unlocked, 512mg, brand new for only $50 more.
At first I didn’t think this phone was much better/different from my $200 lower end phones I always owned but after a couple of days I’m finding this phone is awesome! So many new features and today I just a few minutes ago I had a system update. I can’t wait to see what else it’s going to do, it’s probably going to make the bed or frech toast! 
I thought these said new but maybe I was reading about another model.
I’m thinking about getting another one for my guy! 
ESIM is a chip built into the phone itself, not cloud based. So you can’t just take the SIM out and put into a new phone. I think Apple has ways to transfer it on newer phones/software and I think Android finally does to. You still have to download some information from your carrier though so you will need wifi for first setup. I do not use one so just know what I have read in the past. If you can’t use phone to transfer you would have to call your carrier.
Thank you for a very good explanation of ESIM. Note: The original post was about an SD card, a memory storage device.
It sucks that these companies have gotten rid of the sd slot, headphone jack and most have removed the power brick, and are trying to go esim only. They charge outrageous prices for even less features is mind boggling.
Thanks! I appreciate your explanation. 
I was thinking the same thing about the ability to add my own memory card. They also used to have the ability to switch out batteries…
This way you pay more if you want more memory… how much of a profit are they making when they sell to their distributors? It cant imagine it being a huge amount…?
Im not comfortable wirh cloud storage.
Mind you, these phones can still be utilize sd cards only difference is an adaptor needs to be purchased that has usb c and can read sd cards. Thats one solition
You can still connect a USB-C flash drive to the port and have it read as a mini storage drive.
You could buy brand new from samsung.com for 720$, just need to use a couple of simple tricks.
If done correctly, you could get it even cheaper there (without trade-in).
What tricks? They are $1299 there. I see $250 off
$50 for first purchase using the app, special discount for education/first responders, etc, referral code, and so forth.
And they make adapters to plug into the same USB-C that allows you to plug in an headphone jack for corded headphones. I use one and it works fine as do using bluetooth earbuds. But yes I miss being able to add memory, replace batteries etc. Part of this was to make phones thinner and smaller. Same thing with new laptops that don’t have DVD/CD players.
Does the phone have 2 physical SIM slots?
Hello. From our vendor:
Per Samsung website seems like its 1 physical sim + 1 esim = dual sim
