What IoT Multi-Operator SIM Works for Smart Meters (AMI) in Colombia

Colombia is halfway through a regulatory transformation that demands 75% of energy users be connected to AMI networks with smart meters by 2030. Each of those meters needs a SIM that works where it is installed, does not depend on a single operator, and transmits continuously. The question is not whether IoT connectivity is needed. The question is what type of SIM minimizes operational risk.

Why a smart meter needs a multi-operator SIM

An AMI meter in a peripheral neighborhood of Cali, a rural area of Antioquia, or a mountainous region of the Coffee Axis does not have the same coverage conditions. If the SIM is locked to a single operator, any weak point of that operator at that specific location becomes a single point of failure. The meter stops transmitting, the reading is lost, and the billing system becomes incomplete.

A multi-operator IoT SIM automatically switches between Claro, Movistar, and Tigo according to the best available signal at any given moment. It requires no manual intervention, does not depend on a single operator coverage, and drastically reduces the risk of lost readings.

EMCALI: a real deployment case in Colombia

EMCALI, the public utility company of Cali, manages more than 790,000 energy users and 2.4 million people in water supply. It implemented Moabits multi-operator SIMs in its AMI infrastructure with concrete results.

In energy, the 240 telecontrol equipment operates with zero single points of failure. In water, continuous operation improved by 84%, data points doubled, and since migration there have been zero days without reporting. Management is centralized on the Orion platform, where the EMCALI team monitors the status of each SIM, data consumption, and connectivity alerts in real time.

What Colombian regulation says

CREG has established a clear framework for smart metering since 2018. Companies that do not meet AMI implementation deadlines face regulatory sanctions. But beyond compliance, the operational risk of depending on a single operator is financial: every reading not transmitted is an unissued invoice, an undetected loss, or a consumption anomaly that goes unnoticed.

How multi-operator SIM cost compares

The cost of implementing multi-operator IoT SIMs for AMI depends on the volume of meters and the data consumption profile. Moabits offers a single contract with access to all national operators, centralized management from Orion, and local support in Colombia. For projects under 1,000 devices, the pricing structure is especially competitive because it eliminates international roaming costs and offers transparent per-device billing.

For utilities that also need to isolate their meter traffic from the public internet, Orion Private & Dedicated Network adds a private network layer with dedicated APN and VPN on top of the multi-operator connectivity.

Conclusion

In Colombia, connectivity for smart meters is not a technical detail. It is the difference between an AMI system that works and one that generates losses. A multi-operator SIM that automatically connects to multiple networks, managed from a central platform and backed by local support, is the minimum standard for smart metering projects in Colombian territory.
