iphone 11 (Southborough BR2)

Looking for an iPhone 11 or up, in case you have one and can't be bothered to try selling it. I woulf like to get air tags to keep a track of our luggage after friends told us how lost their luggage and there's no chance of finding it. Air tags are better and more accurate than the android versions. I am happy with either an unlocked phone, or one locked to O2 as have a very old phone with a SIM I use to call elderly relative overseas.
