Better global IoT connectivity for energy and utilities

NB-IoT suits stationary, battery-powered gas, water, and heat meters, with deep indoor penetration and very low power. LTE-M adds higher throughput, which suits electricity meters and sensors that report more often. Whichever your modem supports, one Onomondo profile covers both, plus 2G, 3G, 4G, and 5G NSA, so the SIM never limits your technology choice. NB-IoT availability differs by country, so check the coverage table for each market and use Network Lists to set which networks a meter may use.

Onomondo SIM cards ship with no preset operator list, so the modem attaches to the strongest network at the installation point rather than a carrier’s preferred partner, with multiple networks per country for redundant coverage. NB-IoT gives deep indoor penetration and very low power for stationary meters, and Network Lists let you choose which networks a device may use in each country, optimized for coverage, quality, or cost. If a meter does drop off, Network Logs show every attach attempt and the reason for any failure.

Connectors move cloud SDKs and encryption keys off the device and into Onomondo’s core network, so the meter sends a small payload and the network delivers it over TLS, HTTPS, or MQTTS to AWS IoT Core or Azure IoT. The device transmits less data and runs less logic, which lowers the monthly data bill and extends battery life. If you change cloud endpoint, you update devices in bulk from the platform without touching a single meter.

A meter can only use the network technologies its module supports, so a 2G-only meter loses service when the local 2G network closes, whatever SIM it carries. In Great Britain alone, the Public Accounts Committee estimates 7 million smart meter communications hubs need replacing before 2G and 3G end in 2033. Onomondo covers 2G, 3G, 4G, LTE-M, NB-IoT, and 5G NSA on one profile, so whichever technologies you design your next meter around, the connectivity is already in place, and our 2G and 3G sunset table lists each network’s sunset date to inform that choice.

Onomondo bills per MB with no prepaid bundles and no minimums, so a meter that reports a balance and a daily reading costs less than one streaming interval data. With Magic Mode, you pay only for SIMs that connect within a month, so meters in installer stock and sensors between measurement campaigns don’t accrue cost, and a sensor that runs only half the year costs nothing in the months it stays silent. Data limits and cost alerts per SIM keep the bill predictable across tens of thousands of devices.

You own every Onomondo SIM and its keys, with no lock-in period or exit penalty, and can switch operators over the air to any GSMA-certified operator without recalling a device. With Onomondo’s IoT eSIM and eSIM IoT Remote Manager, you assign an operator per region remotely and enable, disable, or delete profiles in bulk. Within the technologies your meter’s module supports, Network Lists let you change which networks it uses from the platform.
