I bought this from eBay as i wanted to use a flip phone as a break from my Galaxy z fold 6. It says unlocked and refurbished, looks new. it is dual nano sim, but i was not able to make it work with the AT&T network. I'm not sure if i needed to do something other than put my current Nano sim in. That is all that I did, but no luck. the phone is a touch screen and replaceable battery which is nice. I don't know how long the battery lasts as I was not able to use it.
