The Internet of Things is developing at a rapid pace, and various technologies and acronyms are emerging one after another, shaping the future of the Internet of Things. Among them, eUICC, eSIM and multi-IMSI are redefining connectivity standards. Today, I’ll demystify these terms for you and shed light on their significance in IoT deployments around the world.

eSIM explained

eSIM (embedded Subscriber Identity Module) revolutionizes traditional mobile SIM cards (such as micro, nano or mini). Embedded directly into device circuit boards, eSIMs are resistant to environmental threats such as dust and water, paving the way for sleeker, more rugged devices. The eSIM card is compact and non-removable, making it particularly suitable for various IoT applications.

Learn about eUICC

After many years of using traditional SIM cards, I cannot help but highlight the prominent role of eUICC (Embedded Universal Integrated Circuit Card) as a transformative technology. Not only is this technology compliant with GSMA standards, it also offers the versatility to remotely provision and manage network profiles across a variety of different form factors, including eSIM. This flexibility has become indispensable in the globalization of the Internet of Things. However, while bringing momentum to the business, there are also license fees and the complexity of managing multiple operator relationships to consider.

Interpret Multi-IMSI

Navigating the world of IoT can be intimidating, but trust me, understanding terms like IMSI (International Mobile Subscriber Identity) can greatly simplify the process. The unique thing about the Multi-IMSI SIM card is its ability to connect to multiple operators. This guarantees a stable connection that is crucial for IoT, allowing devices to autonomously lock onto the best operator signal. Their adaptability, coupled with the convenience of native IMSI, ensures hassle-free updates and avoids constant SIM card changes.

eUICC and Multi-IMSI

Both eUICC and Multi-IMSI SIM cards are known for their versatility, but they also have different characteristics. The upgrade process for an eUICC SIM card can be somewhat complex and sometimes even costly. In contrast, Multi-IMSI SIM card technology enables automatic profile switching, all from a single connection provider. This simplified approach eliminates download fees for new profiles, making Multi-IMSI an affordable option. One of the significant advantages of Multi-IMSI is its ability to reduce heavy reliance on traditional roaming agreements. With direct connections to local network operators, Multi-IMSI ensures that IoT devices primarily leverage local connectivity, balancing reliance on local and roaming networks for optimal connectivity.
