Connectivity that does not depend on one carrier.

Who we are

Sturdy SIM provides cellular connectivity for connected devices. Our product is a data-only SIM card that is not tied to a single carrier. One Sturdy SIM connects to more than 200 cellular networks, nationwide and around the world.

Why we built it

Every carrier has places it covers well and places it does not, and every carrier has outages. A device with an ordinary SIM inherits all of that. It works where its carrier works and stops where its carrier stops. For equipment that is installed in many places, or that moves, choosing a single carrier means accepting its weak spots.

A Sturdy SIM removes that choice. Because the SIM is permitted on more than 200 networks, a device can use whichever one reaches it, and can move to another if the first is lost.

How we work

We keep the offer simple: one SIM, one account, and one flat price whichever network a device uses. The service carries data only, because that is what connected devices need.

We begin by asking what your devices are, where they will operate, and how much data they use. We confirm that the SIM suits your hardware, we encourage you to test it before you commit, and we remain your single point of contact afterward.
