A key concern with Xiaomi phones in the UK is the lack of support for 4G.
However, the more recent models support Band 20 which is used by many carriers. Even models that only support 1 Band will still receive full 4G speeds, but coverage may be reduced.
*Where 800MHz is available, please check the model you purchase supports it as it can vary.
