What is the reason why the new car's OnStar cannot connect to the network?

It may be due to OnStar system maintenance and updates. Below is the relevant introduction: OnStar: OnStar is the abbreviation of OnStar Information Service Co., Ltd., a joint venture established by General Motors, SAIC Group, and Shanghai General Motors on October 28, 2009. By the end of 2009, it began providing automotive safety information services for the main vehicle models produced and sold by Shanghai General Motors in China. As wholly-owned subsidiaries of General Motors and SAIC Group. Brand Culture: OnStar, leveraging the strong capabilities of North America's OnStar, provides more mature in-vehicle services to Chinese users with a friendly and trustworthy brand personality. Under the brand essence of safety first, simple operation, humanized contact, and serving the public, its service purpose is to always protect the driver's journey.

I just bought a new car, and OnStar keeps having trouble connecting to the internet right after installation, which is really frustrating. Looking back, I didn’t confirm the SIM card activation during the new car delivery, and I might have parked it in a corner of the parking lot with weak signal, affecting the antenna reception. The new car’s battery wasn’t fully charged either, causing the system to start with a delay after ignition—I had to move it to an open area and try again. Also, the subscription status wasn’t synced immediately; I had to wait two days for it to activate after checking the official website. My advice to new car owners is to first check the parking location—avoid tunnels or underground garages—and test by turning on a mobile hotspot. If that doesn’t work, contact customer service to handle activation details. During the break-in period, don’t rush to use complex features to avoid causing more issues.

I often use OnStar and know it operates via a SIM card. For new cars, delayed activation or SIM card failure is a common issue—try restarting the vehicle's system or pressing the reset button. Outdated software versions can also affect connectivity, and updating the system firmware usually resolves it. Dust accumulation on vehicle sensors or antenna damage is rare, but new cars might have assembly issues during manufacturing. It's advisable to park in open areas to minimize signal interference and regularly clean in-car devices. If problems persist, replacing the SIM card or seeking professional repair is quicker—avoid DIY fixes that might damage the wiring.

My new car's OnStar can't connect to the internet, possibly due to subscription issues. The salesperson might have forgotten to activate it, or there could be insufficient account balance - sometimes it takes a few days to activate after purchase. Low battery power may cause slow system startup, check the dashboard status. Occasionally it's user error, like accidentally turning off the data switch, try restoring default settings. It's cost-effective to report faults during the new car warranty period.
