What is the eSIM SGP.31/32 standard?
• The eSIM SGP.31 and SGP.32 standards are the latest GSMA specifications (2023), designed specifically for IoT devices.
• Unlike the earlier SGP.21/22 consumer standards, which were created for smartphones and required user actions such as scanning a QR code or using an app to activate an eSIM, the new standards enable automatic, network-driven provisioning.
• This makes it possible to remotely install, update, or switch profiles on IoT devices that often lack screens, cameras, or user interfaces. SGP.31 defines the technical architecture, while SGP.32 sets out the operational procedures.
• Together, they simplify large-scale deployments, reduce complexity, and support the long lifecycle of IoT devices.
Transatel’s eSIM readiness program
With over 25 years of expertise in delivering global connectivity solutions, Transatel provides strategic guidance and pilot support for your IoT deployments. A three-part consulting and enablement program to help you take control of your IoT fleet.
Training & assessment
• Goal: clarify key issues, demystify SGP.32 and explain its architecture (SM-DP+, IPA, eIM, and orchestrator).
• Format: 1–2 days interactive workshop + diagnostic of current situation (use cases, architecture impacts, SIM supplier contracts, MNO lock-ins).
Vendor coaching & advisory
• Goal: support client in discussions with suppliers, avoid traps and biased sales talk.
• Scope: join calls with MNOs, SIM vendors, orchestrators; critical review of offers; objective feedback based on experience.
SGP.32 pilot environment
• Goal: provide our own SGP.32 environment for real use cases with our multi-operator profile (901) and tools.
• Includes: access to full stack (eIM + orchestrator), help with first integration, option to buy profile + global connectivity + SGP.32 as a service.

FAQs
What is an eSIM? 
An eSIM (embedded SIM) is a reprogrammable SIM that uses Remote SIM Provisioning (RSP) standards to download and switch profiles over the air, without the need to replace the card. You can activate mobile plans remotely, making it faster, more flexible, and ideal for global connectivity.
How does an eSIM work?
An eSIM stores your mobile subscription details securely within a chip inside your device, called an eUICC (embedded Universal Integrated Circuit Card). When you switch carriers or plans, your device can download a new profile over the air – no need to swap cards manually.
What is the difference between an eSIM and a traditional SIM card?
A traditional SIM is a removable plastic card that must be physically swapped to change operators. An eSIM, whether embedded in the device (soldered MFF2 form factor) or provided as a plastic triple-cut card, can be digitally programmed and updated remotely.
What are the different SIM card sizes?
Physical plastic SIM cards come in three main sizes: Standard SIM, Micro SIM, and Nano SIM (triple-cut). Today, Nano SIMs are the most common. Soldered SIMs (MFF2) eliminates these size differences altogether, since the SIM is built into the device.
eSIM vs SIM: which is better?
Both options provide mobile connectivity, but eSIM offers greater flexibility. With eSIM, you can switch carriers without needing a new card, manage multiple profiles on one device, and enjoy a more seamless travel experience. However, traditional SIM cards remain useful for older devices that do not support eSIM.
What is eUICC?
eUICC (embedded Universal Integrated Circuit Card) is the technology behind eSIM. It allows secure storage and management of multiple operator profiles, enabling remote provisioning and compliance with GSMA standards. This makes eSIM both future-proof and globally interoperable.
