RodSanderson , via OnePlus 8T , Feb 13, 2021 : Hello Oneplus ! I bought a Oneplus 8t 5g in Switzerland, but I still haven't 5G. You said it is a carrier problem but it is not. My carrier Swisscom says you have to add their carrier to your supported carriers's list to make Oneplus work in Switzerland. What's the problem ? Apple, Samsung and even Xiaomi are working with Switzerland, so do something please !
