The Hardware Tax on SMS Alarm Alerts Is Getting Worse. There's Now a Better Way.
If your WIN-911 site relies on SMS alarm notifications, you know the setup: a MultiTech or Sierra Wireless device mounted in your control cabinet, a SIM card activated with a carrier, and an unlimited messaging plan running in the background. For years, that was simply the cost of doing business if you wanted reliable SMS alerts from an industrial environment. That cost is going up, and it’s not coming back down anytime soon.
The Market Is Working Against Hardware SMS
The culprit is the AI boom, and its effects are rippling well beyond data centers. The world’s largest technology companies are spending hundreds of billions of dollars building AI infrastructure, and those data centers consume enormous quantities of memory chips – the same DRAM and NAND flash that goes inside every router, modem, and networking device on the market. DRAM contract prices surged over 171% year-over-year as of mid-2025, a pace that outstripped even the price of gold over the same period. For networking hardware specifically, memory costs increased by roughly 700% in a single year according to Counterpoint Research. Industrial cellular modem manufacturers, unlike high-volume consumer electronics makers, don’t have the purchasing leverage to negotiate favorable long-term supply contracts. They buy in smaller quantities, pay spot prices, and pass the increases along.
A second shock arrived in March 2026, when the FCC banned all new foreign-manufactured networking hardware from receiving FCC authorization, citing national security concerns. The practical effect is a shrinking pool of available hardware as existing inventory sells through, with a “Made in America” price premium expected to follow.
We’re already seeing this in our own supply chain. Our hardware supplier has informed us that the modems supported by WIN-911 are set for a steep price increase on our next purchase – roughly 30-35% across the line. That’s not a one-time adjustment; it’s a signal of where the market is heading.
What This Means for Sites Running Hardware SMS
Email-to-SMS gateways, once a workaround some industrial sites used, have become increasingly unreliable as most carriers have restricted or discontinued them. Almost none work anymore; for years, a hardware modem was the only reliable option available.
WIN-911’s hardware SMS path has always required a cellular modem plus a SIM card, carrier activation, and an ongoing unlimited messaging plan. That’s a meaningful upfront investment before a single alarm notification ever gets sent. Moreover, hardware has a finite lifespan. When a modem fails or ages out, that procurement cycle repeats (and now repeats in a market where replacement hardware costs significantly more than it did a year ago). For IT and operations teams managing tight capital budgets, that’s a cost line worth eliminating entirely.
Cloud SMS Changes the Game
WIN-911 2025 R2 introduces cloud-based SMS – the ability to send alarm notifications over the internet without any hardware modem at all. No device to procure. No SIM to activate. No physical component to fail, replace, or budget for. The same two-way SMS functionality operators rely on is fully preserved: alarm notifications, acknowledgments, and report requests all work exactly as they did with hardware, just without the hardware.
The setup works through the SmartSights Edge Gateway, which handles communication between your WIN-911 system and your chosen cloud SMS provider. WIN-911 2025 R2 supports two providers: Twilio and Flowroute, both well-established platforms with straightforward pricing and reliable delivery. You create an account with the provider, purchase a phone number, configure your API credentials in WIN-911 Workspace, and you’re done. All communication is outbound-initiated; there are no inbound ports to open on your firewall, and no additional exposure to your plant network, eliminating any security concerns. For sites already running the Edge Gateway for SmartSights Mobile or XLReporter, therefore, no new infrastructure is required.
The Broader Case for Simplification
Cloud SMS doesn’t just reduce costs. It removes an entire category of operational complexity: one fewer physical device to maintain, one fewer carrier relationship to manage, one fewer potential failure points between an alarm event and the operator who needs to know about it.
For sites evaluating the upgrade to WIN-911 2025 R2 and new sites, the math on moving to cloud SMS is straightforward, especially in a hardware market that shows no signs of getting cheaper. SmartSights will continue to supply and support hardware modems for a while to come still, but you may consider picking up a spare sooner rather than later if Cloud-based SMS isn’t a good fit for your team.
