If you're going for a contract then EE/Vodafone/Three all supply the Huawei 5G CPE Pro (H112-370), but there is a newer CPE Pro 2 model if you buy the router on it's own. It's not cheap though, £350-£400.
As you're not UK based you might have different choices for network, but I think the Huawei routers are the 3 main ones available.
