Unable to Connect to In-Vehicle 4G Network?
2 Answers
Possible reasons for network connection failure include incorrect network settings, poor signal strength in the current location, or issues with the service provider. Below are relevant explanations: 1. In-vehicle 4G network: This refers to vehicles equipped with smart connectivity systems that have built-in 4G network modules, allowing 4G internet access via an installed SIM card. In-vehicle 4G is designed to cater to the daily habits of the post-80s and post-90s generations, creating a new era of vehicle functionality. 2. All-in-one Vehicle LTE-Fi: Features large-capacity storage, high-sensitivity GPS, and high-density connectivity. It uses 4G mobile cellular networks as data transmission channels and provides coverage through WLAN, functioning as a professional LTE-to-WiFi device. Primarily designed for industry, enterprise, and commercial clients, it can meet various internet access scenario requirements.
When I find that the in-car 4G connection fails, I usually troubleshoot step by step. Weak signal is a major issue, especially when parked near tall buildings or in remote areas—trying an open area might help. Restarting the infotainment system can resolve temporary glitches; just hold the power button for a few seconds. If the SIM card is improperly inserted or damaged, reinserting it or replacing it with a new one is necessary, ensuring the carrier supports it. Incorrect APN settings are common, so check the infotainment settings for compatibility. Account expiration or exceeding data limits can cause disconnection, requiring a login to the app for top-up or renewal. Hardware issues like modem failures are rare, but overheating can cause malfunctions—restart after cooling. For safety, avoid handling these while driving; operate only when parked. Preventively, regularly clean antenna dust, keep the system updated, and avoid interference sources like near power towers.
