Why Trafalgar Wireless IoT SIM Cards
Access to Global Connectivity
Our IoT SIM cards provide access to over 500 cellular networks across 180 countries. These networks support 2G, 3G, 4G LTE, 5G, LTE-M, and NB-IoT networks, as well as automatic access to new network options as they become available.
Reliability
Sourced from Giesecke+Devrient, one of the world’s leading SIM card manufacturers, our IoT SIM card solutions are manufactured to the highest specifications, ensuring their reliability and longevity in the toughest of environments.
Multi-IMSI Capability
Streamline your connectivity management with a SIM card for IoT that switches between multiple subscriber identities, controlled by an intelligent SIM Applet. Multi-IMSI solutions enable the use of different networks in different geographies, to deliver the most suitable and economic service per region.
Multi Form Factors
We provide SIMs either in plastic form factors 2FF, 3FF, and 4FF, Tr-Cut, or as an embedded form factor MFF2.
MFF2 SIM cards are soldered directly onto the device’s printed circuit board (PCB). This saves space and reduces the risk of malfunction.
Multi Component Grades
Plastic SIMs are further offered in M2M grade or Industrial grade, to suit the heat, humidity, and vibration exposure of your device.
eSIM and eUICC
eSIMs utilise eUICC technology and can be remotely reprogrammed with the subscriber profiles of different mobile carriers. This allows for greater flexibility and ease in switching between carriers without the need to physically replace the SIM card.
We provide a range of SIMs, to ensure that this critical technology component matches your precise requirements:
- Matching your network choice
- The size needed to suit your device
- Plastic or Embedded Cards
- The durability needed to suit your device’s environment
- Traditional SIMs (UICC) or eSIMs (UICC)
Conventional SIMs
Our conventional IoT SIM cards are designed to meet a wide range of connectivity needs. From durable plastic SIM cards to space-saving embedded options, these SIMs provide reliable performance in various environments.

FAQ:
Trafalgar Wireless provides IoT SIM cards for a wide range of device categories used in real deployments. Common examples include asset and freight trackers for logistics and construction equipment, where industrial-grade/eSIM options keep devices connected across borders and rugged sites. You’ll also find extensive support for sensors, from inventory and warehouse monitoring to outdoor environmental sensing, powered by multi-IMSI coverage and durable SIM form factors. For vision use cases, Trafalgar enables video telematics/camera systems that stream events and upload incident footage for fleets.
In energy & utilities, Trafalgar highlights connectivity for smart meters and related infrastructure, leveraging industrial/embedded SIMs and eSIM/eUICC. Across these device types, the same SIM portfolio (plastic 2FF/3FF/4FF, industrial, embedded, and eUICC) rides on 500+ networks in 180 countries, with LTE-M/NB-IoT, LTE/5G options and management through the IoT Suite, so you can standardize connectivity even in harsh conditions.
Yes. Trafalgar Wireless supplies IoT SIM cards in all common plastic form factors, 2FF (mini), 3FF (micro), and 4FF (nano), including tri-cut variants for flexible field deployment. For rugged or space-constrained hardware, we also provide MFF2 embedded SIMs that solder to the PCB to resist vibration and temperature extremes, ideal for long-life M2M devices.
You can choose traditional UICC profiles or eUICC/eSIM for remote SIM provisioning (RSP) and multi-profile flexibility, so fleets can switch carriers over-the-air as coverage or commercial needs change. Trafalgar highlights both eSIM and eUICC options across its SIM portfolio and IoT data plans, giving you a future-proof path without hardware swaps.
In short: whether you need 2FF/3FF/4FF plastic, industrial MFF2 embedded, or eUICC/eSIM capability, Trafalgar Wireless offers a complete lineup of IoT SIM card form factors to match your device design, durability requirements, and global rollout strategy.
Trafalgar Wireless IoT SIM card solutions are built to be radio-agnostic across generations. The IoT Data SIM Form Factors page states support for 2G, 3G, 4G LTE, 5G, LTE-M, and NB-IoT, with access to 500+ networks in 180 countries, so you can standardize one SIM portfolio for legacy devices and new low-power sensors as well as 5G rollouts.
For low-power use cases, Trafalgar offers LTE-M and NB-IoT data plans (where the local carrier provides coverage) and also lists 5G data plans, helping teams transition as networks evolve and regional 2G/3G sunsets proceed on different timelines.
Because the same SIMs are available in plastic (2FF/3FF/4FF), embedded MFF2, and eUICC/eSIM options, with multi-IMSI capability, you can remotely steer devices to the best available network technology per country without a truck roll, keeping fleets online through coverage gaps and technology shifts.
Yes. Trafalgar Wireless equips its IoT SIM cards with enterprise-grade network isolation options. You can deploy a Private APN to keep device traffic off the public Internet and operate in a closed, policy-controlled network. With a Trafalgar Private APN, you can control IP addressing and set your own access policies, limiting connectivity to approved devices and improving performance by reducing external traffic.
For encrypted transport, Trafalgar offers a site-to-site IPsec VPN, creating a private tunnel from your network to Trafalgar’s global PoPs, so telemetry and commands travel securely end-to-end. If you prefer to avoid the Internet entirely, Trafalgar Connect provides a direct metro-ethernet link to your cloud or data center for mission-critical workloads.
Together, Private APN + IP control + IPsec VPN (and optional private connectivity) give you layered security for global fleets using Trafalgar Wireless IoT SIM cards. If your architecture requires alternatives such as GRE or SSL-based tunnels, the team can evaluate options with you during design.
