This situation is usually caused by downtime. A SIM card with GPS positioning is inserted into Chezhihui, just like a mobile phone card. This situation will occur if China Mobile or a certain communication company settles the bill at the end of the month or the beginning of the month, or if the data is used up frequently due to frequent car use in the last month. A new month has begun. Unplug the device and plug it in again to see if it recovers. If it has not recovered yet, open the device, take out the SIM card, and contact customer service to check the data traffic.
