The MT24’s 4G-based functions, including sleep mode, parking monitoring, remote viewing, and Cloud Spirit app features, all rely on mobile data. To use Cloud Spirit properly, a compatible 4G SIM card must be inserted into the device.

If you have inserted a 4G SIM card but the MT24 still cannot access the network, please check the following:

1. Please check whether the mobile data indicator appears next to the signal icon on the top-right corner of the screen. It may look similar to “↑↓”. The signal icon alone does not mean the SIM card has been recognized. Only when the mobile data indicator appears together with the signal icon does it mean the SIM card has been inserted correctly and recognized by the device.

2. Make sure the SIM card is inserted after fully disconnecting power
Before inserting the SIM card, please unplug the MT24 power cable completely. Simply turning off the motorcycle ignition is not enough.

The correct process is:

Unplug the MT24 power cable completely.
Insert the SIM card properly.
Reconnect the power cable.
Start the motorcycle again.

After the device recognizes the SIM card, you should hear a voice prompt. Once the prompt finishes, the mobile data icon should appear, which means the device can start using the network.

3. Check whether your SIM card frequency bands are supported
Please confirm that your SIM card is compatible with the MT24’s supported frequency bands.

MT24 supports 2G/3G/4G Full Netcom frequency bands:
B1, B3, B5, B8, B38, B39, B40, B41

4. Check whether APN settings are required
Some SIM cards may require APN settings before they can access the network on external devices. This is similar to some Android AI boxes for cars: the SIM card may be inserted correctly, but mobile data will not work until the APN is properly configured.

If the MT24 still cannot access the network after checking the above steps, please contact us at support@linkifun.com with your SIM card country and carrier name. We will forward the information to our solution provider for further checking.
