Quectel's technical explainer argues that SGP.32 eSIM defers the operator decision from production to deployment: a tracker ships with an eUICC and IPA.d support, then receives and enables a local profile remotely through an eIM. With more than 80 percent of connectivity spend sitting in the subscription and a lifetime eSIM cost advantage around 8 percent, Kaleido Intelligence expects roughly 50 million SGP.32 eSIMs under management globally by 2027.

An asset tracker is built in China and shipped inside containers, vehicles or high-value cargo to Europe, Southeast Asia, the Middle East and Latin America. GNSS fixes the position, cellular carries the data back — on the surface, GPS plus a SIM card. A technical explainer published by Quectel on 10 October 2026 points at a lower layer of the problem: once devices are sold into different regions, a connection locked in at the factory degrades cost, network quality and serviceability at the same time. The answer it proposes is SGP.32 eSIM.

The price of going dark is higher than the price of the SIM

The traditional approach is to fit a SIM before shipment and keep the device on international roaming abroad. Quectel lists three concrete consequences. Cost scales with volume: a single tracker consumes little data, but at 100,000 or a million units the roaming rate turns into a material annual line item. Network quality is not under the customer's control, because one SIM relies on different networks in different regions, and fewer selectable networks means a higher chance of going offline. The most practical problem is that the device has already been sold — trackers sit inside vehicles, containers, construction equipment and shared assets, so asking the end customer to open a unit and swap a SIM is not realistic.

Industry analysis explains why the subscription dominates. Research by Transforma Insights, commissioned by Quectel and published in March 2024, finds that more than 80 percent of connectivity spend is the subscription itself, with components and logistics accounting for little. On a like-for-like basis, eSIM devices cost about 8 percent less over their lifetime, a gap that widens to 11 percent when the eSIM is integrated into the module, and 13 percent for iSIM. The lever is on the tariff side — and whether the tariff can be optimised depends on whether the device can change profile at all.

What SGP.32 actually moves

SGP.32 is the GSMA technical specification for remote eSIM provisioning in IoT, paired with the SGP.31 architecture and requirements specification. The architecture appeared in April 2022, the technical specification reached v1.0 in May 2023, v1.1 in April 2024 and v1.3 by May 2026. The associated test and certification specification, SGP.33, was published in January 2025 in three parts covering the eUICC, the IPA and the eIM/SM-DP+.

Against SGP.22 for consumer devices and the older M2M specification SGP.02, SGP.32 changes three architectural things: it removes the SM-SR, so any GSMA-compliant SM-DP+ can deliver a profile to an eUICC holding a valid activation code; it drops the SMS dependency in favour of IP transport, adding CoAP/UDP/DTLS for constrained devices and allowing HTTP/TCP/TLS for broadband ones; and it supports both push and pull download models.

On the device and platform sides the roles divide as follows:

  • eUICC — stores and runs multiple operator profiles, in pluggable, soldered MFF2/MFF4 or integrated iSIM form factors.
  • eIM (eSIM IoT Remote Manager) — the server-side orchestrator that issues profile download, enable, disable and delete operations to one device or an entire fleet, and collects notifications.
  • IPA (IoT Profile Assistant) — the device-side execution layer, implemented either in device firmware as IPA.d or inside the eUICC as IPA.e; the eIM and SM-DP+ behave identically either way.
  • SM-DP+ — reused from SGP.22 rather than reinvented, so existing platforms carry over.

Autonomy ultimately hinges on eIM Configuration Operations (ECO): addEim, deleteEim and updateEim determine whether a deployed eUICC can be moved to a different eIM. The specification defines them; whether a given provider exposes them is a commercial rather than technical question, and it is the question to ask before assuming lock-in has disappeared.

How a tracker bound for Germany switches profile

Quectel describes a complete path: the device integrates an eUICC and supports IPA.d, establishes connectivity through a Bootstrap Profile, and uses that connection to download its operational operator profile. Once the device lands in Germany, the platform prepares a profile according to enterprise policy — Operator A for Germany, Operator B for France, Operator C for Brazil — and the eIM then issues the management task while the device-side IPA completes the download, installation and enablement. No field engineer visits the unit, and no user scans a code or touches a screen.

The commercial effect is straightforward. Of one production batch, 1,000 units can go to Germany on a local profile, 2,000 to Brazil on regional operator resources, and 5,000 can stay in the warehouse with no connection resource committed in advance — one hardware SKU, with connectivity following the business. SGP.32 does not change what a tracker does: GNSS still fixes position and cellular still carries the data. It changes which network the device connects to, and who decides that, and when.

Standards and market pace

Kaleido Intelligence's eSIM Market Outlook & Opportunities 2025, published in April 2025, expects combined consumer and IoT eSIM connections to grow from 500 million in 2024 to 4.5 billion by 2030. SGP.32-compliant eSIMs began commercial rollout in the second half of 2025, with roughly 50 million SGP.32 eSIMs under management globally by 2027. The firm's Connectivity Data Hub forecasts that SGP.31/32 deployments accelerate from 2027, that close to a quarter of eSIMs activated for IoT use cases will sit on SGP.32 architecture by 2029, and that activated eSIMs in IoT pass one billion in 2028.

Demand-side volumes are expanding in parallel. Berg Insight estimates the installed base of tracking devices on trailers, containers, rail freight wagons, air freight ULDs and returnable transport packaging will rise from 13.8 million units in 2024 to 26.9 million in 2029, a 14.3 percent CAGR, while trackers and real-time data loggers for general cargo grow from 4.9 million to 16.2 million units. Market value for the segment is forecast to grow from EUR 2.7 billion in 2024 to EUR 4.5 billion in 2029. The larger the fleet and the higher the cross-border share, the more expensive a factory-locked connection becomes.

What it means for hardware and supply chain

  • SKU consolidation — one global hardware version, with connectivity decided by profile; inventory planning shifts from stocking SIMs per country to managing connectivity per region.
  • Form factor decided early — the choice between pluggable eUICC, soldered MFF2/MFF4 and iSIM belongs to the design phase; iSIM removes the socket and assembly steps but constrains module and chipset selection.
  • Certification timing — SGP.33 was only completed in three parts in early 2025, and interoperability testing across eUICCs, IPAs and eIM/SM-DP+ platforms is still widening, so volume projects need to confirm the certification status of the parts they select.
  • Compliance and permanent roaming — some markets restrict devices that roam permanently; a local profile is safer on both network priority and compliance, which is the practical value over a pure roaming design.

HSY Perspective

SGP.32 matters because it defers the connectivity decision from production to operation, letting a tracker collapse into a single global SKU at design time; remote profile switching is only the mechanism. The cost structure explains why: more than 80 percent of connectivity spend is the subscription itself, according to the Transforma Insights analysis commissioned by Quectel in March 2024, while components and logistics are minor. Moving a device onto local tariffs therefore outweighs saving a few cents on SIM procurement, and the same study puts the lifetime cost advantage of eSIM at about 8 percent, or 11 percent when integrated into the module. Volumes point the same way: Berg Insight expects the installed base of cargo-carrying-unit trackers to reach 26.9 million units by 2029, and Kaleido Intelligence expects roughly 50 million SGP.32 eSIMs under management globally by 2027.

That yields an ordering rule for both procurement and engineering: settle the eUICC form factor and whether the design supports IPA.d or IPA.e before negotiating tariffs and operator combinations. Tariffs can be renegotiated annually; the eUICC form factor, certification status and firmware capability are effectively irreversible after volume production. An eUICC that does not support eIM Configuration Operations cannot be moved to another eIM once deployed, which replaces M2M-era operator lock-in with platform lock-in. Designs with ECO capability keep the option to reconsider the connection years later as tariffs, coverage or regulation shift — the substance of the locally hosted Brazilian eIM that Acceleronix and Valid brought up on 7 October 2026 with interoperability across both IPA.e and IPA.d.

The judgment has boundaries. It assumes complete specifications and broad certification: SGP.32 v1.3 and all three parts of SGP.33 are published, but interoperability testing between eUICCs and eIMs is still widening, and a project that must reach volume production in 2026 on a module supporting only SGP.22 or a proprietary scheme will not realise the benefit. The second boundary is timing, since scaling is expected from 2027 onward: smaller programmes adopting SGP.32 today are largely buying future optionality, and the near-term bill may not fall immediately.
