Better global IoT connectivity for smart cities and infrastructure

Onomondo’s IoT SIM cards are non-steered, so a device in a garage or cabinet attaches to whichever of 680+ networks reaches it with the strongest signal, instead of a carrier’s preferred partner. NB-IoT gives deep indoor penetration and very low power for stationary devices, and Network Lists let you choose the networks a device may use in each country. These M2M SIM cards come as a plastic SIM, a solderable MFF2, an eSIM, or a SoftSIM; industrial grade is rated from -40°C to +105°C with 15-year retention for a roadside cabinet. They carry data and SMS only, with no voice or phone number.

Network Logs show every attach attempt, the network and technology used, and the reason for any authentication failure. Traffic Monitor captures every packet to and from the device in real time and exports it as PCAP, with nothing installed on the device, so you can tell whether the fault is the device, the local network, or the provider. Most debugging happens directly on the platform, without a support ticket, so a fault in a cabinet or garage is a configuration change from your desk rather than a crew in the street.

Onomondo bills per MB with no prepaid bundles and no minimums, so a sensor that reports once a day costs less than a gateway that’s polled every hour. With Magic Mode, you pay only for SIMs that connect within a month, so vehicles in winter storage and hardware waiting at installers don’t accrue cost. Network Lists let you optimize the networks a fleet uses for cost as well as coverage and quality. Set data limits and cost alerts per SIM so one chatty device can’t run up the bill.

Yes. The same SIM, SKU, and APN work in every market, so you ship one hardware design to every tender rather than a variant per country, and SIMs arrive ready to connect. Network Lists let you pick the networks each region may use, per country or per SIM, and if a contract requires a specific local operator, Onomondo’s IoT eSIM lets you assign one per region remotely. Filter and bulk-edit SIMs by country and tag, set data limits and alerts for a whole city at once, or do it all through the API and webhooks.

Whether a streetlight controller or parking meter survives a 2G or 3G shutdown depends on the radio technologies its modem supports, not on the SIM. Onomondo covers whatever you choose to deploy with: one profile works across 2G, 3G, 4G, LTE-M, NB-IoT, and 5G NSA networks, with multiple networks per country, so the SIM never limits your choice of modem. Our 2G and 3G sunset table lists sunset dates per network, which helps you pick a modem for equipment that will be in the street for 10 years, and Network Logs show which network and technology every installed device attaches to, so you know which units depend on a closing network.

Yes. Onomondo shows live data and cost per device and per fleet, and every SIM is billed on its own usage, so there’s no shared pool to run dry. Set a data limit and a cost alert on each SIM, get a webhook when a device crosses a threshold, and export a monthly CSV per SIM, network, and country. A gateway that’s being polled every hour for no reason shows up in the per-SIM figures the same month, so you fix the behavior instead of paying for it.
