Chevrolet offers customers with OnStar Wi-Fi an unlimited 4G LTE data plan via AT&T for $20 per month

Context & Ripple Effects
AT&T has been building out car-based connectivity for two years: it sells the ZTE Mobley diagnostic-port hotspot for vehicles without built-in Wi-Fi, while GM has been wiring OnStar LTE into its fleet since announcing partner travel information and driving-habit tracking back in 2015. The new $20 unlimited plan turns that installed hardware base into a pricing weapon.
The move lands just weeks after AT&T launched its own $100 standalone unlimited plan that throttles after 22GB, making the in-car offer — unlimited at a fifth of the price — a striking internal contrast, and it follows Verizon's attempt to monetize short-burst usage with PopData's $2-$3 timed streaming sessions.
First-order effects
- Chevrolet owners with OnStar Wi-Fi get unlimited 4G LTE for $20/month through AT&T, giving passengers a data pipe independent of any phone plan.
- AT&T gains a captive distribution channel inside GM vehicles, selling connectivity at the point of hardware rather than competing for subscribers at retail.
Second-order effects
- Verizon, which bet on metered micro-sessions with PopData, faces pressure to match flat-rate in-car pricing or cede the connected-vehicle segment.
- The $20 unlimited rate undercuts AT&T's own $100 consumer plan, forcing the carrier to justify why smartphone customers pay five times more for throttled 'unlimited' service.
Third-order effects
- If automakers keep bundling carrier service into vehicles, cars become a pricing wedge that erodes the premium carriers charge for mobile data generally — with each OEM potentially auctioning its dashboard to the lowest-bidding network.
The trend: Carriers are using connected cars as a low-price entry point for unlimited data, decoupling connectivity from smartphone plans and turning vehicles into a competitive battleground.
