eSIM & eUICC-Enabled IoT SIM Cards
Future-Proof Your IoT Devices with Cutting-Edge Connectivity
eSIM and eUICC allow remote SIM provisioning, saving space and future-proofing devices for evolving networks.
Exploring eSIM & eUICC SIM Technology
Trafalgar Wireless provides IoT Data Plans in conjunction with SIM Cards. These are available in numerous different form factors. One key innovation in this area is the emergence of the eSIM, along with a closely related technology called Embedded Universal Integrated Circuit Card (eUICC).
Initially, the term ‘eSIM’ was a reference to the SIM card being embedded onto the printed circuit board (PCB) of the device. However, eSIMs are now also available with traditional plastic form factors as well.
What distinguishes eSIMs – whether embedded or plastic – from their more traditional SIM cousins is their ability to be remotely programmed:
Remote SIM Provisioning
Unlike traditional SIM cards, which are physically inserted into a device, eSIMs allow SIM profiles to be downloaded and provisioned remotely over-the-air. This allows users to switch between different networks without needing to physically swap SIM cards.
Space Saving
For eSIMs which are integrated into the device’s hardware, they save physical space compared to traditional SIM cards. This is especially important for devices with compact designs, such as smartwatches and IoT devices.
Future-Proofing
eUICC technology enables devices to support future network technologies and standards. This helps prolong the lifespan of devices and ensures compatibility with evolving mobile networks.
Key Features of eSIM & eUICC Technology
Future-Ready Connectivity
eSIMs with eUICC technology are engineered to evolve with your needs. Unlike traditional SIM cards, eSIMs allow for seamless network profile updates over the air, eliminating the need for physical replacements and future-proofing your devices for evolving technologies.
Space-Saving Design
eSIMs are integrated directly into a device’s hardware, reducing the need for a physical SIM card slot. This makes them ideal for compact devices such as wearables, IoT sensors, and smart meters, optimizing design and durability.
Effortless International Roaming
eUICC technology supports multiple network profiles on a single eSIM, enabling devices to switch between carriers as needed. This ensures uninterrupted global connectivity for devices operating across borders.
Multi-Form Factor Options
eSIMs are available in embedded MFF2 formats for space efficiency or traditional plastic forms (2FF, 3FF, 4FF, Tri-cut) for flexible deployment, ensuring compatibility with a range of devices and applications.
Durable & Secure
eSIMs are built to withstand harsh conditions, offering the same resilience as industrial-grade SIM cards. Advanced encryption and security features protect sensitive data, ensuring secure communication between devices and networks.
Consistent Longevity
With a lifespan comparable to industrial SIM cards, eSIMs provide reliable performance even in extreme environments, from high temperatures to remote locations.
IoTSuite Management Platform

FAQ:
Trafalgar Wireless supports broad global coverage for eUICC eSIM for IoT deployments. Their multi-network and global IoT data services are built to keep devices connected across borders, with roaming and multi-profile capabilities enabled through eUICC technology. In fact, Trafalgar Wireless states that their IoT connectivity can provide access to over 500 mobile networks in about 180 countries through a single SIM/eSIM source, which is ideal for international or multi-region IoT rollouts.
On a country/network level, they also highlight strong U.S. support: Trafalgar Wireless can provision localized eSIM profiles on AT&T and Verizon, and add a roaming profile for T-Mobile, allowing IoT devices to switch carriers over-the-air without swapping a physical SIM.
So whether your eUICC eSIM for IoT devices operate only in North America or move across continents, Trafalgar Wireless can match you with the right mix of local, roaming, or multi-network profiles to deliver reliable coverage where your devices need to be.
Yes. Trafalgar Wireless supports 4G/LTE and 5G Non-Standalone (NSA) connectivity across its IoT SIM and eSIM offerings, with access delivered via existing LTE network infrastructure. 5G NSA allows devices to benefit from 5G data capabilities while relying on LTE cell towers for control signalling, which provides broader coverage than full Standalone (SA) 5G that is typically limited to major urban areas. Support for LTE-M and NB-IoT is available where the underlying carrier network supports these technologies, making them suitable for low-power, low-data IoT use cases such as sensors, metering, and tracking. Trafalgar Wireless focuses on modern LTE-based technologies rather than legacy 2G/3G, reflecting current global network availability and long-term IoT deployment requirements.
Because eUICC enables remote SIM provisioning, Trafalgar Wireless can also shift devices between supported networks and technologies without truck rolls or physical SIM swaps, helping you stay compatible as coverage, standards, and carrier options change.
Yes, Trafalgar Wireless supports device binding through IMEI locking, and it can be used alongside their eUICC eSIM for IoT deployments. Trafalgar Wireless describes IMEI Lock as a security applet pre-installed on the SIM/eSIM that prevents misuse by locking the SIM to the specific device using it. This IMEI/ICCID-style device binding can be enabled at provisioning time or through their API, and the locked IMEI can later be disabled over-the-air (OTA) if you need to redeploy a device.
For IoT fleets, this is a practical safeguard: if an eUICC eSIM is removed or cloned, it won’t function in an unauthorized device, reducing fraud and protecting your data plan spend. Combined with Trafalgar Wireless’s remote SIM provisioning and multi-profile eUICC capabilities, IMEI Lock gives you both flexibility and control, you can securely “bind” connectivity to approved hardware while still switching carriers or updating profiles OTA as your IoT rollout scales.
