What happened to SGP.32 in 2025?

SGP.32 arrived in 2025 as a long‑awaited evolution of eSIM standards for IoT. It’s a big promise: SGP.32 is purpose-built to fix the complexity and restrictions around remote SIM provisioning. 

It aims to standardize how enterprises choose, switch, and manage connectivity but, while the marketing has raced ahead, adoption has been slower and more uneven.

That said, vendors are clearly starting to roll out hardware and software match, and we’ve seen a handful of real‑world SGP.32 device deployments visible so far. Let’s take a look.

‍

Recap – What Is SGP.32?

‍

SGP.32 is the GSMA’s next‑generation remote SIM provisioning (RSP) standard designed specifically for IoT, separating it from the consumer‑focused SGP.22. The new standard is also intended to be an improvement on earlier M2M specifications. 

At its core, SGP.32 defines how eUICCs in IoT devices download, enable, disable, and delete operator profiles over the air – with promises to enable the best eUICC SIM for smart devices.

It merges the best features of previous standards: it retains the robustness of the older M2M (SGP.02) architecture while adopting the flexibility and "push-pull" profile management of the Consumer (SGP.22) model. 

This hybrid approach allows devices to download and switch network profiles over-the-air without needing the complex, carrier-side integrations that hampered previous enterprise deployments.

Compared to the standards currently in use, SGP.32 brings to the table a more flexible architecture that is better suited to access constrained devices, headless deployments, and large‑scale fleet management.

A Quick History of The Evolution Of SGP32

‍

The journey to SGP.32 has been a decade-long exercise in closing the gap between industrial power and consumer flexibility. It began in 2014 with SGP.02 (M2M), a standard that was revolutionary for its time but relied on a push architecture. 

It required complex, pre-arranged integrations that could lead to vendor lock-in and high operational hurdles for smaller enterprises. 

By 2016, the GSMA introduced SGP.22 (a consumer standard), which simplified things by using a "pull" model where the user could fetch a SIM profile via a QR code or app. That, however, doesn’t work for headless devices like the millions of IoT sensors buried in smart meters or shipping containers. Without a screen and human operator these devices simply didn’t have the ability to pull profiles.

In May 2023 the GSMA released the initial SGP.32 specification as the "best of both worlds," taking the robust remote management of the M2M world and pairing it with the lightweight, flexible profile delivery of the consumer world. 

Throughout 2024 the standard matured with the release of version 1.2, which finalized many technical requirements.

Vendors Are Slowly Tooling Up With SGP.32 Product Releases

‍

Though we didn’t see much in the way of large scale practical rollouts of SGP.32 in 2025, there is good news in that the ecosystem spent 2025 getting its SGP.32 story straight to enable the best eUICC SIM options. Yes, many providers are still in trial or beta, but the products and services that are emerging are concrete.

We’re seeing SGP.32‑capable modules, a few operator and cloud‑platform integrations, and many early trials announced. A few examples include: 

• SIMCom added SGP.32‑capable remote‑provisioning firmware to its LTE Cat 1 bis IoT module families, which enable OEMs to deploy to “headless” devices that can be remotely provisioned and updated.
  
  
• Giesecke+Devrient and Murata announced an integrated SGP.32‑ and iSIM‑compliant cellular connectivity module which combines Murata hardware with a G+D eUICC/RSP stack – combining radio, secure element, and standardized remote SIM provisioning in a single compact footprint.
  
  
• IDEMIA launched a fully GSMA‑certified SGP.32 eSIM solution (eUICC plus server‑side RSP platform) for IoT, which can act as a standards‑compliant infrastructure that MNOs and enterprises can use to remotely manage IoT profiles at scale.

​Needless to say, real-world implementation for SGP.32 to deliver the best IoT SIM options relies on the availability of concrete, tested solutions. Vendor rollouts therefore add to the promise of SGP.32 in the field for 2026.

What About SGP32 Out In The Wild In 2025?

SGP.32 remained largely experimental through 2025, with real-world deployments confined to pilots and niche verticals like smart metering, asset trackers, and enterprise gateways rather than widespread adoption. Nonetheless these are powerful proofs of concept; high-profile tests include:

• Globe Telecom trialled SGP.32 with Thales in the Philippines to enhance enterprise IoT connectivity, focusing on seamless profile switching for multi-carrier support. The 2025 trial demonstrated faster activations and better roaming for business applications like telematics and metering. It positions SGP.32 as a booster for reliable, scalable IoT in emerging markets.
  
  
• G+D integrated SGP.32 eSIM into Amazon's eero signal boosters, which highlights SGP.32's role in bridging consumer and enterprise connectivity boundaries.
  
  
• Links Field, Hapolo, and SIMCom launched Brazil's first SGP.32-enabled 4G tracker in 2025, targeting logistics and asset tracking. The device leverages eSIM for global roaming and remote profile management, simplifying deployments in Latin America.

It’s clear that the era of rigid, locked-in IoT connectivity is coming to a close. Throughout 2025, we have seen the industry’s major vendors ready products infrastructure to prepare for the new GSMA standard. 

While the past twelve months were defined by these foundational integrations and successful trials, the momentum is clear: SGP.32 is evolving rapidly, and we expect a surge of live, large-scale use cases across all industrial sectors in 2026.

At GigSky we’re working hard on adopting SGP.32 to deliver the best IoT SIM with multi network support – including the most flexible deployment options.
