Semtech's SGP.32 eSIM lets IoT makers ship one SKU and add local carriers later

One SIM part number goes into every unit, and the local carrier gets chosen once the device is in the field. Semtech made that its offer on November 9, when the SGP.32 version of Smart Connectivity Premium became generally available, according to the company's announcement on Business Wire. The eSIM pairs Semtech's own global connectivity profile with local mobile network operator profiles on a single SKU, and all of it is managed from the AirVantage eSIM orchestrator.

Semtech's release names three problems the product targets: reliance on a single carrier, which brings lock-in and outage risk; countries that restrict permanent roaming; and having to physically swap SIMs when a network shuts down or a provider changes. For the connectivity lead at a meter, camera or tracker maker, the real question is narrower than "is SGP.32 good". It's whether Semtech's version takes enough of that per-country work off the bill of materials and puts it into software.

How the profile stack works

Manuel Nau, lead editor at IoT Business News, describes the single-SKU design as the core of the offer: one common eSIM configuration whose operator setup can change to match local network availability.

The base layer is Semtech's multi-IMSI Smart Connectivity Advanced profile. Premium customers add MNO profiles on top of it to localize deployments across technologies and data usage volumes, according to the release. The local profile sits alongside the global one rather than replacing it, which is how Semtech can pitch the same unit as both a global and a local product.

AirVantage handles orchestration, bulk provisioning, subscription management and lifecycle operations. Semtech says it runs on AWS. Teams can work in the AirVantage interface or plug it into their own platforms through APIs. On the device side, a Semtech applet on the eSIM downloads, enables and switches profiles when needed, so nobody has to trigger each change by hand. Nau's reading is that this moves part of the connectivity workload from device-by-device provisioning to central software.

Multi-profile is not new for Semtech. Smart Connectivity Premium offered it under the older SGP.02 specification. Rupa Datta, Semtech's vice president of IoT Connected Services, said in the announcement that the SGP.32 version adds deployment flexibility, from a preloaded eSIM through to self-configuration. Existing Semtech customers should read it as an upgrade in how profiles get onto devices. The capability itself was already there.

Meters, cameras and things that move

Semtech maps the product to two kinds of deployment. Fixed assets such as smart meters and video surveillance systems get one SKU with the global profile plus local operator profiles, which handles permanent roaming restrictions and gives a failover path. Mobile assets get several carriers across regions for coverage and resilience.

Semtech also names non-terrestrial networks as a possible future addition for mobile assets, though IoT Business News points out that the launch does not include any specific satellite operator integrations.

Nau frames the underlying problem in terms of time: these devices are often expected to run for many years with minimal physical intervention. Over a service life that long, the network a meter was commissioned on can shut down or a provider can change. Under the SGP.32 model, the answer to either is a profile switch handled in software instead of a visit to the site to swap a SIM.

Battery budgets change the configuration

Battery-powered devices go a different way. Semtech's PowerSave eSIM is a multi-network, dual-profile configuration built for battery-constrained devices, designed to optimize network attach time and help transfer critical data without draining the battery. It ships preloaded. The full Premium solution is the one that lets customers download extra MNO profiles on top of the Smart Connectivity Advanced profile.

Nau argues the split matters because connectivity flexibility and power consumption are not independent. For battery-operated devices, he writes, network attachment behavior and profile management have to be weighed alongside coverage when choosing a connectivity architecture. A device with a tight energy budget could gain more from shorter attach times than from a longer menu of downloadable carriers.

Whichever configuration a customer picks, it is managed through AirVantage. That suggests a maker with both fixed and battery-constrained product lines could run them from one orchestration account, choosing the eSIM configuration per product rather than per platform.

Same standard, several orchestrators

Zacks Investment Research, in an analysis by Om Jaiswal, notes that Semtech faces competition from Digi International and Cisco Systems in the global IoT connectivity market. Digi International offers SGP.32-compatible eSIMs with remote carrier switching and profile management through Digi Remote Manager. Cisco has an eSIM Orchestrator in its IoT Control Center that supports SGP.32 and handles bulk download, activation and management of profiles.

Both rivals arrive with momentum. Digi posted record revenue of $139 million in the third quarter of fiscal 2026, up 29% year over year, per the same analysis. Cisco's industrial IoT orders grew at a double-digit rate for the ninth consecutive quarter in its fiscal fourth quarter, driven by deployments in manufacturing, utilities and data center facilities. Utilities show up on both sides here: Cisco counts them among its growth drivers, and Semtech leads with smart metering as a fixed application.

Put those side by side and a pattern shows. Since every one of these vendors can follow the standard, the standard alone doesn't separate them. What a buyer can compare is the orchestration software and, above all, which local operator profiles each vendor can actually deliver in the countries where the devices go. Nau makes a similar point: the practical gain depends on suitable operator profiles being available in each target market.

That is also where the case for Semtech's offer is most open to challenge. The company says it will add carriers and markets in the months ahead but has not published an operator list or a rollout schedule, so today's coverage needs checking country by country. Berg Insight principal analyst Fredrik Stalbrand, quoted in Semtech's announcement, put eSIM use at roughly 12% of cellular IoT devices at the end of 2025 and said SGP.32 lowers the barriers by simplifying remote provisioning and profile management. With most cellular IoT devices still running without an eSIM, the fleets that could still move to this model far outnumber those already on it.

A single SKU whose operator subscriptions can be adapted remotely over the product's life suggests hardware production decisions could be separated from connectivity provider selection. For an OEM, that would move the carrier decision out of the production plan and into the deployment plan, made market by market after the hardware is built.

Investors read the launch more modestly. Simply Wall St sees it fitting Semtech's growth story only at the margin, with high-margin AI data center silicon as the center of gravity. On the IoT side, its analysts frame one SKU, the SGP.32 applet and AWS-hosted orchestration as aimed at scaling device counts without a matching rise in operational overhead. That is a useful test for buyers as well: whether adding devices in a pilot adds work for the connectivity team.

Questions for the connectivity shortlist

1. Which local operator profiles are available today in each country on the deployment plan, and which ones are only promised for later?
2. Does the device's battery budget point to the preloaded PowerSave configuration or the full downloadable Premium model, and can both live in one AirVantage account?
3. Will profile switching run through the AirVantage interface or through APIs into the existing device management platform, and who owns that integration?

The next thing to watch is the carrier roster. Each operator Semtech adds widens the set of countries where one SKU can ship and be provisioned locally without a separate SIM build.
