The OnePlus 7 Pro 5G is currently only available in the UK, but it seems the smartphone will soon launch in China as it has bagged 3C certification.
The OnePlus 7 Pro 5G is just the regular 7 Pro coming with Snapdragon X50 modem that enables 5G connectivity. And, unlike the 4G variant, the 5G model is only offered in a single storage option - 256GB.
You may not have several 3G and 4G/LTE bands you need in Europe.
I live in the UK and was considering the Oneplus 7 Pro 5G. How ironic that I'll need to import one from China because I'm with Vodafone UK. The exclusive deals with certain networks is ridiculous.
