Haval F7 suddenly unable to connect to the 4G network may be due to a network module issue. Below is a relevant introduction about the car dashboard: Introduction to the car dashboard: With the advancement of electronic technology and the emergence of new sensors and electronic display components, automotive electronic dashboards have been rapidly adopted. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. The function of the car dashboard: The car dashboard display serves as a device that reflects the working conditions of various vehicle systems, allowing continuous monitoring of the car's status and providing drivers with necessary operational parameter information. It is an important interface for information exchange between the driver and the car.
My Haval F7 had the same issue a while ago. It was working fine one minute, then suddenly the 4G network dropped, which really annoyed me. I rely on 4G for navigation and music while driving, so being unable to connect was a real inconvenience. I thought it might be a signal problem, but even in areas with good coverage, the issue persisted. After asking around, I learned that the 4G module in this car is prone to minor glitches—like system cache buildup causing freezes or oxidation on the SIM card contacts. I tried restarting the infotainment system by holding the power button on the center console for about 10 seconds until it fully shut down, then turning it back on. Surprisingly, it worked temporarily and reconnected. If this doesn’t help, check the network settings for any disabled 4G options or try using a mobile hotspot as a stopgap. But if this keeps happening, don’t take it lightly—head to the 4S店 ASAP. It could be an antenna failure or a software update needed, and addressing it early saves hassle.
My F7 had a 4G outage last month, the navigation just cut out while driving, so frustrating. I suspect it's mostly the infotainment system acting up or the SIM card not seated properly. Don't panic, try troubleshooting yourself first: restart the Bluetooth and 4G functions on the dashboard; if that doesn't work, check the SIM card slot, take out the nano-SIM, clean off any dust, and reinsert it—sometimes a loose connection causes signal loss. I've experienced this before, where moisture gets into the antenna connector during humid weather, leading to intermittent disconnections. If you can't fix it, use your phone's app to connect to the car's hotspot as a temporary solution—don't let it delay your plans. Remember to regularly clear the system cache to prevent this issue.
