If you’re unable to sync your SIM card’s call history and SMS to Xiaomi Cloud, please refer to the following to resolve the issue:
1. Ensure that Xiaomi Cloud has permission to access call history and messages.
2. Ensure that call history and SMS syncing are enabled;
3. Ensure you have a stable internet connection. Syncing requires a reliable connection to upload data to the cloud;
4. Ensure that you have enough storage space in your Xiaomi Cloud account. If the storage is full, you need to free up space or upgrade your plan;
5. Make sure your SIM card is correctly inserted into the device. A loose or improperly inserted SIM card can affect syncing your call history and SMS;
6. Make sure your device is running the latest software version;
7. Try signing out of your Xiaomi Account and then signing back in to sync;
8. Restarting your phone can resolve temporary issues and help with syncing.
If the issue persists, please submit feedback through your phone for further assistance.
