What's the reason for no signal on Tesla's 4G data?

[DiRicardo]

Tesla 4G data no signal solutions are as follows: Change location: Actually, car network signals are just like mobile phones. When the vehicle is in underground garages, tunnels, or areas with strong signal interference, the signal can become very poor or even completely disappear. At this time, you can first drive the vehicle to an open area and then check if the car's network is restored. Generally speaking, when returning to an area with a stronger signal, the car's system will reconnect to the network. Check the SIM card: All cars with internet connectivity features rely on a mobile operator's SIM card to connect to the network. You can remove the SIM card from the slot and check if there is any dirt on the chip. If there is dirt, clean it and reinsert it, and the problem is likely to be resolved. If the problem persists, you can call the operator to check if the SIM card has an unpaid balance.
