It is very strange that there are 2 apps for Samsung Pay with different information when you have your Smartwatch and a Samsung phone with it already configured. Also, the feature set appears to be different. While on my phone I have the feature of having a transport card in Stockholm, in the watch it appears that I don't so I am afraid I won't be able to use Samsung Pay interchangeably between my phone and watch as I will not take advantage of reduced pricing if you use your transport card multiple times during the day or month...
Does anyone know a way around this?
5G stands for 5th Generation of mobile connectivity - that is - the latest released standard which operators just are starting to utilise. For you it means faster data transfer speeds (if you live in an area where the network operators has rolled it out). Read more about it here; https://en.wikipedia.org/wiki/5G
