FAQ- Mercedes-Benz C-Class W204 Android Screen

Some customers who purchased the UGODE Android screen for the Mercedes-Benz C-Class W204, which features wireless CarPlay and Android Auto, have encountered some questions while using it and have contacted us for assistance.

Q：

Hello,

I have a Ugode
12.3” Android 13 Snapdragon screen for Mercedes-Benz W204 with NTG4.5.

I have installed a SIM card in the screen. The SIM card has a 4G signal and mobile internet works perfectly.

However, I have a question regarding phone calls:

When I call the SIM card number from another phone, the call reaches the Ugode device and I can hear the ringing tone, but no incoming call screen appears on the Android display. After the call ends, I only see a missed call notification.

Could you please confirm:

1. Does the 4G SIM card in this Ugode unit support incoming and outgoing voice calls, or is the SIM card only for mobile data?

2. If voice calls are supported, how exactly do I enable and configure this function?

3. Is there a specific Phone/Dialer application or setting that needs to be enabled?

4. Does the SIM need to support VoLTE or a specific network configuration?

I would appreciate step-by-step instructions for my specific unit.

Thank you.

Hello,

The SIM card in the Android screen can only be used for internet access, not for making phone calls.

You need to pair your phone’s Bluetooth with the Bluetooth on the Android display to make calls using the Android screen’s Bluetooth.

Thank you.
