Every executive who has approved a connected product roadmap has made a quiet assumption: the network underneath it will still be there. That assumption is about to be tested at a scale the automotive industry has never faced.
The global connected vehicle installed base is heading toward a billion units, and the cellular technology most of those vehicles depend on is scheduled to begin its retirement before the end of the decade.
For automakers, fleet operators, insurers, and the telecom carriers that serve them, the question is whether the recurring revenue those services promise can survive a connectivity layer with a shorter life than the vehicle carrying it.
How Scale Meets an Expiry Date
Omdia research forecasts that the global connected vehicle installed base will surpass 1.05 billion units by 2035, up from 473.7 million in 2025.
Few installed bases of any kind more than double in a decade, and this one signals that connectivity is moving from premium differentiator to baseline expectation.
That trajectory implies a compound annual growth rate of 8.3 percent.
The pace is steady rather than spectacular, which is precisely the point. Every model year adds vehicles whose connectivity assumptions were fixed on the factory floor, so exposure compounds quietly alongside revenue.
The pressure point is timing.
Omdia notes that mobile network operators begin decommissioning LTE infrastructure from 2030. This is not a single global switch-off; telecom carriers will retire the technology on their own schedules, market by market.
A patchwork of sunsets is harder to plan around than a date on a calendar.
Omdia also expects this transition to hit automotive harder than the earlier retirements of 2G and 3G, because LTE now underpins safety-critical services and revenue-generating features rather than peripheral conveniences.
The research points to tighter service level agreements, over-the-air update programs, and service-based architectures as the next phase of the market, and each of those depends on connectivity that stays reliable for the life of the vehicle.
Outlook for Connected Vehicles Evolution
The structural problem is a mismatch of lifecycles. A vehicle stays on the road for well over a decade, while a cellular modem is frozen at a single technology generation the day the car leaves the plant.
Software updates can extend features; they cannot turn a hardware module into a different radio.
In my advisory work with technology and telecom leaders, the costliest failures rarely come from the technology itself. They come from commitments made on one timeline and funded on another.
For the CFO, that means stress-testing connected revenue forecasts and warranty exposure against modem generations, not just unit volumes.
For the CTO and CIO, it means treating eSIM, multi-generation modems, replaceable telematics units, and hybrid terrestrial and non-terrestrial connectivity as architecture decisions rather than component choices.
For the tech vendor chief product officer and the CRO, it means refusing to sell service level agreements that outlast the network commitments behind them.
Fleet buyers and enterprise procurement teams hold more power here than they realize.
Before the next vehicle purchase, ask which modem is installed, whether it can be physically replaced, who pays when it must be, and how long the manufacturer commits to running the cloud services behind it.
Telecom carriers, meanwhile, have an opening to sell migration and continuity services rather than simply watching a legacy network wind down.
The 2030 date is a starting gun, not a deadline, and that ambiguity is exactly why waiting is expensive.
The executives who treat connectivity continuity as a core product promise will protect the recurring revenue everyone is forecasting. So here is a question for your next planning session: if your connected service plan for 2033 assumes the modem shipped in 2025, who absorbs the gap when the network moves on?
