When one cellular network is weak, congested, or down, a Sturdy SIM can move the device to another. No site visit and no SIM swap.
Learn moreCoverage on 200+ Networks
Nationwide coverage across the major cellular networks, and roaming on carriers around the world, all from the same SIM.
Learn moreOne Flat Price
A single price for connectivity on every network. No separate rate for each carrier, each region, or each roaming partner.
Learn moreData-Only Connectivity
Cellular data for routers, trackers, sensors, terminals, and cameras. No voice service, because machines do not need it.
Learn moreSIMs for Fleets & Device Makers
For fleets and production runs of devices in the field. One SIM to specify, one supplier, and one price to build into your product.
Learn moreNo carrier lock-in
If one network goes down, your device moves to another.
A device with an ordinary SIM depends on one carrier. When that carrier has an outage, or simply does not reach the site, the device goes offline. A Sturdy SIM is permitted on more than 200 networks, so one carrier is never a single point of failure. That is why we can guarantee 100% reliable connectivity.
