Phone condition excellent. Not a scratch on it and works rapidly with good battery life. I've previously had the identical phone brand new and don't notice the difference between this and a brand new phone - other than the price.

Item seemed in better condition than I expected so that was good. I just didn't know at the time of purchasing it if it had the features I wanted and had to go ahead and purchase it before I was able to contact the seller to enquire about some features. There should be an option to contact the seller before purchasing the item from the seller. Anyway, this phone is a lot more modern and packed with more features than my previous Nokia 1 Plus phone. Still looking for how to get it to play music automatically when it's connected to my car's bluetooth otherwise it's a great phone.

Purchased the dual sim version of this phone. The phone I recieved only allowed for a single sim. This phone is to replace my older phone which is same model with the dual sim function. This is my first time purchasing through Backmarket, so hopefully this is just a rare issue.
