Just got a galaxy watch 46mm and couldn't get Samsung pay to work, was informed that the watch is from the Baltic region and Samsung pay doesn't work with them
Trust me on this one do not go to apple, cut a long story short I broke my s10 plus, went to apple and it was horrible, I got an 11 Pro, I was missing texts other notifications and was even missing calls, the ringer volume would go up and down it was awful and apple support did nothing, I then came back to Sammy on an s2o and all is good, fair enough if you want to leave Sammy but don't go to crapple
there's your issue then ebay is the worse place you can buy a phone from, always used a trusted retailer like Samsung them selves carphonewarehouse or argos, I don't even buy from amazon just in case
I see what your saying but coming from ebay that phone could be from anywhere, I tried to sell a Samsung wave years ago on ebay and they wanted me to post it to Nigeria I told them to shove it and sold it to a friend
