Review: Good fone for the money - Bought this fone cuz my Samsung Galaxy S20 ultra stopped sending texts and no one could figure it out. I even factory reset the fone twice Verizon went all though the setting nothing. So I was looking for fone in the $200 range and saw this. It's smaller but I dont need a mega sized screen anymore. So far had the fone around 4 months and it's been great it's light weight and fits in my hand and pocket good. I Was able to transferred all my apps, music and contacts over with Samsung smart switch in 10 mins. The glass on here isn't very strong not like the S20 ultra witch I dropped a good amount of times no screen cracks or scratches. This S21 didn't hold up to that I was on my couch half a sleep dropped the fone under 2 feet and it sent 3 cracks across the whole screen. I didn't know it was cracked instill a few days later when the sun hit it at the right angle. I still have on the shipping screen protector not sure if that's holding it together not gonna peel it off to find out. It's been cracked for over a month now no issues with digitizer or screen tracking. It's a Octa core processor and 8 gigs of RAM it's a fast fone for all my needs even with multiple windows open in internet browser and other apps running in the background. I run my fone even on battery saver you wouldn't even know its saving energy wakes up fast no studering flips though screens fast. Fone did come like described in excellent condition. Just buy a case for it and the glass prob would have survived. Get this fone to save on your fone plan not buying there flag ship fones for high prices.
Review: Very good quality for a used device👌 - I started using it a few days now. There are some scuff marks around the edges, but I have it in a case, so they are not visible, the screen and back are in pristine condition no scratches or scuff visible. I thought the description said unlocked, but it was locked to AT&T. Great news is that I was able to get the unlock code from att within minutes from their website, they have a page for unlocking, you only need to provide the imei and your email and their system sent the code within the same minute. Then the other hurdle was that the phone was stuck on android 12 and kept on saying there are no updates available. Turns out that you have to be an ATT customer to continue getting updates for an ATT device. The workaround is to manually flash the original firmware to the device which I was able to do. Now it has android 14 installed and working perfectly fine 👌

### ⭐ Deceptive Title and Descriptions
*by M***N on March 12, 2026*

It's NOT truly unlocked. The ESIM portion is actually still locked by AT&T. Physically SIM works fine, but if you are going to eventually switch to ESIM, do not buy this. It is amazing how they branded it as T-Mobile unlocked, well of course it is, because it was locked by AT&T, afterall, not T-mobile.
