LTE-M SIMs for IoT and M2M connectivity
Connect to over 100 LTE-M networks globally with Onomondo’s powerful IoT network and connectivity platform.
LTE-M is a versatile IoT cellular network technology
LTE-M cellular standards (CAT M1, Cat M2) were made for low-power, wide-area (LPWA) applications. You can use LTE-M SIMs in a broad range of use cases, including asset trackers, smart meters, agriculture sensors, and smart buildings.
Low power
Great coverage
Most use cases
The world’s largest LTE-M network.
Onomondo SIMs have access to more than 100 LTE-M networks worldwide. Our core network steers traffic, giving you access to networks with one SIM.

LTE-M SIMs in every form factor.
Onomondo SIMs offer global coverage with all form factors (2FF, 3FF, 4FF, MFF2, eSIM, MFF-XS, SoftSIM) and architectures (UICC and eUICC). It has never been easier to develop, deploy, and operate IoT devices locally or worldwide.

LTE-M SIM vs. NB-IoT SIM
LTE-M and NB-IoT are developed for IoT, but not suited to all use cases. This comparison table will guide you on the value that LTE-M SIMs or NB-IoT SIMs bring so you can decide which one fits better to your industry or use case.
LTE-M SIM | NB-IoT SIM | |
---|---|---|
Uplink/Downlink | High (Mbits/s). LTE Cat M2 offers max 7 Mbit/s uplink and 4 Mbit/s downlink. | Low (kbit/s). LTE Cat NB2 offers max 159 Kbit/s uplink and 127 Kbit/s downlink. |
Coverage/Penetration | Great coverage and penetration. | Great coverage and penetration. |
Global availability | Great availability where LTE already exists. Built on existing LTE technology. | Good availability. Requires new infrastructure that is cheaper to roll-out than standard LTE. |
Roaming capability | Good roaming availability. Check regions of interest. | Technically possible, but basically non-existent in reality. Check regions of interest. |
Module costs | LTE-M modules are typically slightly more expensive than NB-IoT. | NB-IoT modules are typically slightly cheaper than LTE-M. |
Power saving features | LTE-M standards support PSM and eDRX but availability depends on local networks. | NB-IoT standards support PSM and eDRX, but availability depends on local networks. |
Mobility | LTE-M is suitable for static and mobile applications. | There’s no handover when moving with NB-IoT, making it best suited to static devices. |
Remote provisioning | Supports SMS. Freedom to leave and eUICC (eSIM) remote provisioning are possible. | Typically no SMS support which is not good for eUICC (eSIM) remote provisioning freedom to leave (changing SIM operator). |
How Aguardio uses LTE-M to save water.
Aguardio’s IoT shower and leak sensor provides insights that can help buildings and organizations reduce water consumption.

The world’s first 100% software LTE-M SIM.
SoftSIM is a 100% pure software SIM that requires no physical SIM cards or SIM chips. SoftSIM is the world’s first agnostic connectivity solution designed for IoT to save power, lower complexity, and reduce costs.
