Battery health was supposed to be 93% and it came with 89%

The Sim card tray in the phone was missing. I'm very disappointed because the phone was supposed to arrive in mint condition.

Edit: I contacted customer support and they sent me a new sim card tray. I had to wait a few days for that to arrive. They also sent me a phone case to make up for their mistake, but the case wasn't received in the best condition either. It had a big scratch on the back. Although a case is better than no case, I'm still kinda disappointed.

I got a TMobile phone instead of Verizon

Phone said to be unlocked is in fact locked to comcast, and won't receive any other SIM card. i'm only using on WiFi, but not happy with the seller and felt it was misrepresented.

Only good thing about this sell, phone was received on time, phone battery was at 0% charge when arrived. Finally had a chance to move to this phone, it is clearly deflective, dropping network and LTE, radio switching to 2G all the time, have to reboot every 10 minutes to get LTE back.

I’m a bit disappointed my phone was sent to me without the SIM Card Tray. They did send it out but I still had to wait a while for it to get here.

Device arrived with Sim Tray.
Seller made the effort to send a replacement, but the color does not match the iphone.
It's a concern the missing piece was not indicated in the item description as I would not have buy the device, as all the photos used for selling the item indicate the presence of the sim tray.
Also, this missing piece (containing the serial and IMEI of the iphone) means it would more than likely not be supported by Apple warranty.

I bought a cell phone in perfect condition and it came with huge risk on the screen. Upon contacting I was given a refund of 15 dollars. I recommend removing the protective film to see if the device is really in good condition.

Purchased a phone that was advertised as a T-Mobile device. Had issues connecting to my carrier (T-Mobile) and when I called T-Mobile customer care, they informed me that the phone was actually a Sprint device and would not work properly on the T-Mobile network. To be fair, the phone was in mint condition as advertised, it was just too bad they advertised the carrier incorrectly.

At the time, there were no other T-Mobile S10 5G devices for sale on Swappa, so I would have to purchase a different model. When I asked for compensation for all my trouble (time wasted, no phone, dealing with shipping, non-refundable accessories purchased for a specific model), both the seller and Swappa said there was nothing they could do.

Quite disappointed with the poor customer service overall. To add insult to injury, the seller took their time confirming they had received my return and providing a refund date. I had to follow up several times. :(

This sale was a complete and utter failure because the phone had some Knox Cloud Service software on it that seems to be for a work-provided phone. I was unable to uninstall it or get past this software to be able to use the phone, and received no help from TPSC. I put on a screen protector and put it in a case to protect the phone when I went to get the sim card. I will use the case when I replace the phone, but TPSC said they would not reimburse me for the screen protector because it wasn't purchased through them. I hope they change their mind and credit me for that, as the phone now has a screen protector on it if they are able to remove that software and resell it. Not at all impressed with TPSC thus far. If they make things right, I'll say so in a subsequent posting. If they don't, find someone else to purchase your phone from.

Update: TPSC did nothing to help me and did not reimburse me for the screen protector. Buy from someone else.
