• 📞 Operator services - VoLTE support (voice on the LTE), ViLTE (video calls), Wi-Fi Calling.
• 🔄 Updates to the profile SIM — automatic updates for correct card operation (for example, when changing the tariff).
• 🛡️ Security — authentication SIM-Cards, fraud protection (e.g. substitution) IMSI).

On Xiaomi smartphones, this application is preinstalled in firmware MIUI It works in the background, even if you've never run it, and without it, some features may not work properly: for example, VoLTE won't connect, or the phone won't be able to automatically switch to a faster network if the signal is lost.

Carrier Services and custom firmware: compatibility and challenges

Users who install informal firmware (such as LineageOS, Pixel Experience, or HavocOS) often find that Carrier Services is either missing or not running smoothly.

• 📱 Some assemblies do not include proprietary libraries for working with SIM-map.
• 🔄 Operator configuration updates do not come automatically.

To make Carrier Services work on custom firmware:

1. Make sure that the firmware supports GApps (Google Service Package).
2. Install the latest version of Carrier Services manually (APK-file).
3. Check if the carrierconfig file is available in /system/etc/ — He is responsible for setting up operators.
4. If VoLTE doesn’t work, try patching. IMS Patch (available on forums such as XDA Developers).

• 🌐 Using Wi-Fi Calling through third-party apps like Google Fi or Skype (but it won’t replace regular calls).

However, it is not possible to completely replace Carrier Services, since it is responsible for low-level modem settings.

• ❌ Automatic update of operator configurations.
• ❌ Support for VoLTE and ViLTE.
• ❌ Stable roaming work.
• ❌ Protection against fraud SIM-map.

If you are willing to make these sacrifices, you can try disabling the app (as described above), but we recommend keeping it active for the network to run smoothly.
