One SIM card. More than 200 cellular networks.

The problem with a single-carrier SIM

Every carrier has places where its signal is strong and places where it is weak or absent. When you buy a SIM from one carrier, you inherit that carrier's map. A device installed in a basement, at the edge of town, or in a metal enclosure may have a poor signal from one carrier and a strong signal from another. With a single-carrier SIM, there is nothing the device can do about it.

What a multi-network SIM does differently

A Sturdy SIM is a roaming SIM made for connected devices. Rather than belonging to one carrier, it is permitted to use more than 200 cellular networks. When the device powers on, its modem looks for the networks that are within reach and registers on one of them. If the device is moved, or if that network becomes unavailable, the SIM can register on another.

One card to stock, wherever it is going

Organizations that deploy devices in many places often end up holding SIMs from several carriers, then sending someone to site to find out which one works. A multi-network SIM removes that step. The same card goes into every device, and the device finds its own coverage after it is installed.

Made for machines

A Sturdy SIM carries data and nothing else. It is intended for routers, trackers, sensors, terminals, cameras, and other equipment that sends and receives data without a person holding it. It does not provide voice calling and is not a replacement for a mobile phone plan.

Every SIM size, 5G, and LTE-M

Sturdy SIM is available in every SIM size: standard (2FF), micro (3FF), nano (4FF), and embedded (MFF2). It supports 5G for devices that need speed and LTE-M for small, low-power devices, as well as standard LTE, so the same service suits a high-capacity router and a battery-powered sensor.

A single price

Coverage on many networks does not mean a different rate for each one. Sturdy SIM is sold at one flat price, so the cost of a device does not depend on which network it happened to connect to this month.
