China version – please read before buying
- Google Play: Not pre-installed. It can usually be added, but this is not guaranteed and it can stop working after system updates. Some Google features may not work.
- Pre-installed apps: Chinese apps and a Chinese keyboard come pre-installed. English can be selected as the system language.
- Contactless payments: Google Pay / Google Wallet tap-to-pay is not available or not guaranteed on China-version phones.
- UK networks: Supports the main UK 4G bands (1, 3, 7, 8, 20 and 28, including 800MHz and 700MHz) and the main UK 5G bands (n1, n3, n7, n8, n20, n28 and n78) according to published listings, so it should work on UK networks; this is not guaranteed as it uses Xiaomi’s own new chip platform. VoLTE and Wi-Fi calling depend on your network supporting imported phones.
- Charger: Any charger in the box is a China-market charger and will usually need a UK plug adapter.
