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. Once launched, the OnePlus 7 Pro 5G will compete with the Huawei Mate 20 X (5G) in China which is slated to go on sale from July 26. Via
