This is a very strange post, but a few month ago, I believe this was in May, I purchased a BNIB galaxy s21 ultra 512GB version (flag ship) off of kijiji(this is our classifieds). So it was a private sale. I actually should have suspected something when an item is BNIB as most carriers does not do BNIB.
All of sudden my carrier's data stopped working as of a week ago. I called into technical support and got them to send me a new sim card. However as it turns out, my phone is BLACKLISTED in Canada(possibly the Unite states too).
This item will however work out side of Canada and U.S. or if you think you can get better value on ebay or something.
Anyways. I have original box with MATCHING IMEI so I definitely did not just randomly swipe this phone off of a stranger.
If you are interested send me a message. I'm selling this item for $800USD(spot price btc, escrow or multisig or whatever, my trust is at +9) + shipping if you are interested, for anyone in Eur, Asia, Aus etc.
picture is available if you want.
it's 9.9/10 condition because it's not new, but there are no cosmetic damages, i've used it, but ofc with screen protector and case from day 1.
You will NOT be getting the case, as I purchased a new s21 ultra from Samsung as of yesterday.
I definitely had a similar experience with this. I purchase it and is asking for deactivation unless I register an account.
