Global Version vs Global ROM
The regional versions of Xiaomi devices
Xiaomi devices, which are officially sold outside of Mainland China, usually come in three versions.
Global versions are manufactured in Mainland China and sold in the rest of the market - mainly North America and Europe. The box's language and the power adapter's plug varies by region, but the phone always comes with the Global Stable ROM pre-installed. Global versions support more LTE bands so they will work with the Carriers in your country. Global versions have a red 'Global Version' sticker on the box and most resellers offer both the Global and Chinese versions of a phone when they exist.
When a Global Version of the phone is not available, the Chinese Version can have a Global ROM installed. A Global ROM is necessary because Chinese Versions do not have acces to the Google Play Store and its apps. So, A Global ROM is simply a piece of software that will allow your phone to acces the Google Play Store. The other thing to watch out for is that Global ROM installed phones may not have support the LTE bands of your country's cell phone carriers. It's important that you check on a site such as: https://www.kimovil.com/en/frequency-checker to ensure that the phone can support the frequencies of your country's carriers.
Important: We only sell Global Versions or Chinese Versions with Global ROMs
Chinese versions are manufactured and sold in Mainland China, they come in a Chinese box with a NEMA plug power adapter and the China Stable ROM pre-installed. Chinese versions of Xiaomi devices can be installed with a Global ROM to make them more useful for North American and European markets.
Warning: On Chinese versions manufactured after May 2018, it's not possible to boot the Global Stable/Developer ROM with a locked bootloader.
Indian versions are manufactured and sold in India, they come in an English box with an IN plug power adapter and the Global Stable ROM pre-installed. Indian Redmi devices support significantly less LTE bands than Chinese versions, because only a fraction of those bands are used in India. Resellers who are dealing with Indian versions are extremely hard to come by. Indian versions have a red 'Made in India' sticker on the box.
