Powering Millions of Devices
Different applications have different SIM requirements. Our multi-network SIMs are purpose-built for IoT and Edge AI – every one ships with our intelligent multi-IMSI applet. Choose your form factor; the underlying network stays the same, with built-in compliance and full control from one centralized platform
Our infrastructure keeps data local, reduces latency, and meets data sovereignty rules wherever your devices operate.
Operate legally in countries with strict regulations. Reliable coverage. Access 2G, 3G, 4G, 5G, LTE-M, NB-IoT and Satellite NTN.
Our SIMs enable autonomous network switching, so your device automatically connects to the next available network. No reboots, no downtime, no manual intervention.
Combine the benefits of our multi-IMSI applet with the flexibility of eSIM SGP.32 and SGP.22 if needed.
Configure your SIM settings including coverage and failover behavior based on your deployment needs. Our team helps get your connectivity strategy right.
Lock each SIM to a specific device IMEI. If a SIM is swapped to an unauthorized device, it stops working, protecting your devices from misuse and unwanted costs.
Velocity IoT offers every major SIM form factor and connectivity technology, giving you the flexibility to access all major U.S. carriers on one SIM, scale across borders, add redundancy, and future-proof your hardware.

Key Capabilities
Advanced SIM technologies for ultra-compact devices, wearables, sensors, and module-integrated designs.
Adjust profiles, IMSIs, and SIM settings over the air. Skip SIM swaps and field visits. Easily expand into new markets or adopt new connectivity technologies.
Only pay for what you use. SIMs that aren’t registered on the network don’t incur charges.
Manage multiple carriers through one centralized platform with APIs, reducing administrative overhead while simplifying troubleshooting.
Whether you’re testing a prototype or planning a global rollout, our team can help you choose the right connectivity solution and discuss free trial data for your project.
Not all IoT SIMs are built the same. Here is how Velocity IoT’s multi-IMSI SIMs compare to single-profile eSIMs, local SIMs, and roaming SIMs.
| Feature / Capability | Velocity IoT Multi-IMSI SIMs | eSIM Platforms | Local SIMs | Roaming SIMs |
|---|---|---|---|---|
|
Global coverage |
750+ networks in 190+ countries, plus satellite fallback |
Yes, dependent on operator profile agreements |
Country-specific only |
Depends on roaming contracts |
|
Local access across networks |
Local access via distributed core, including all major US carriers through a single SIM |
Profile-dependent: local routing only with a local profile |
Fixed to one local operator |
Depends on roaming agreements |
|
Compliance & data sovereignty |
Local breakout, compliant per region |
Depends on host MNO and location |
Fully compliant, country-specific |
Data often crosses borders |
|
Automatic failover |
Autonomous network switching with fallback logic |
No native failover |
Manual intervention required |
Usually no failover |
|
Updating SIM profile / IMSI |
OTA updates for IMSIs and SIM settings |
Requires eIM for RSP |
Manual SIM swap required |
Tied to home operator |
|
Performance (latency & throughput) |
Optimized via local breakout |
Depends on operator’s gateway location |
Direct local connectivity |
High latency, home-routed |
|
Integration simplicity |
One platform, one vendor |
Varies per provider |
Multiple MNOs, fragmented |
One platform, one API |
|
Business model flexibility |
Pay only for active SIMs. Flexible models from self-serve to enterprise |
Often tied to MNO license models |
Fixed monthly plans per SIM |
High roaming fees, inflexible |
Rugged Telemetry deployed Velocity IoT’s multi-IMSI SIM for primary cellular connectivity in Watertown’s wastewater system, with access to all major U.S. carriers.
The result: real-time monitoring, reduced downtime, and 99% uptime with resilient connectivity.
Multi-IMSI and eUICC solve the same problem – access to multiple carrier networks from a single SIM – but in different ways. Multi-IMSI stores multiple operator credentials on the SIM and switches between them based on rules you define, with no remote profile download required. eUICC (eSIM) downloads new operator profiles over the air using GSMA standards (SGP.22 for consumer, SGP.32 for IoT). Velocity IoT SIMs include a multi-IMSI applet by default; our SGP.32 eUICC SIMs combine both – the multi-IMSI applet is provisioned as the initial profile.
Roaming SIMs connect to foreign networks through a single home operator, which often introduces latency, home-routing of data, and permanent roaming compliance issues. Multi-IMSI SIMs hold multiple local operator credentials and connect to networks as a local subscriber – giving you local breakout, lower latency, and regulatory compliance in countries with strict permanent roaming rules.
Yes. A single Velocity IoT SIM provides access to all three major U.S. carriers – AT&T, T-Mobile, and Verizon – with automatic switching between them. No SIM swaps, no regional SKUs.
Velocity IoT SIMs are device-agnostic for any device compatible with 2G-5G, LTE-M, or NB-IoT and not locked to a single carrier. Available in 2FF, 3FF, 4FF, and MFF2 form factors, with iSIM and SoftSIM available on supported modules.
You only pay for SIMs that are active and transmitting data.
Yes. Both our multi-IMSI UICC SIMs and our eUICC SIMs support OTA updates. Multi-IMSI applet updates, IMSI additions, and SIM setting changes can all be pushed remotely from the Velocity IoT platform. SGP.32 eUICC SIMs also support full remote profile download.
Yes. Through our Velocity Flex platform, SIMs are available directly on Digi-Key with no minimum order quantity and no contract required. For enterprise deployments and custom SIM setups, contact our team.
For self-serve buyers, SIMs ship directly from Digi-Key. For enterprise deployments, our team typically scopes and activates SIMs within days, including any custom SIM configurations or network strategy work.
