Xiaomi SIM Activation Service
SIM authentication process to access exclusive features in certain MIUI applications.
For the activation to work you need to send a international SMS to China.
Your carrier may block this by default and/or you’ll probably need to pay extra for this.
After SIM activation, you can send text messages (Mi Messages) to other Mi users using internet connection (like i-messages).
You will be able to synchronize your messages into Mi Cloud and this also enables the Mi Find Device feature which allows you to track your phone’s location from your online Mi account.
Note: To enable/disable Mi Messages go to Settings -> System Apps -> Messaging and reboot
