    Was new in box when received, not used or refurbished. Dual sims seem to work as advertised, Orange SIM works in France and West Africa, Verizon and Orange SIM worked in Belgium. Fired right off with my Verizon SIM at home (US) and no problems in several states, no bloatware to go with it though, darn! 🙂 Battery life seems about the same as my old S9, not great but OK. Overall very happy with purchase!

    I had a tough time justifying the cost of this phone. ATT said I needed to upgrade to a 5G phone. There are not many 5G dual sim card phones out there, so I went with this one. Man, it looks so much faster than my own phone. I did not realize how with my old phone, I was often waiting for apps and screens to load. This new phone is fast. Even as a “used” phone, it still had the protective sticker on the rim of the phone. Another perk is there was not that much bloatware. Works great with my car.

    The battery life sucks but picture quality is great. Wasn’t reading my fingerprints could be because of the tempered glass. Overall it’s not bad.
