Coverage wherever a cellular network reaches.

Coverage is local

Carriers describe their coverage as a percentage of the population, but a device is installed at one address. What matters is which networks reach that address, at that height, inside that enclosure. In cities several networks usually overlap. In rural areas, along highways, and inside buildings, it is common for one network to be strong where another is absent.

Combining the maps

Because a Sturdy SIM is permitted on more than 200 networks, its coverage is the combination of all of them. If any one of those networks has a usable signal at the device, the device can connect. This is the simplest way to improve coverage without changing the antenna or the hardware.

Nationwide in the United States

In the United States, a Sturdy SIM gives a device access to coverage from the major national networks and from regional carriers, rather than from one of them alone. A rollout across many states can use the same SIM at every site, including the sites where your usual carrier is weak.

Around the world

The same card roams on carrier networks abroad. Equipment that is shipped overseas, or that travels across borders, does not need a different SIM for each country. Availability varies by country, and some countries limit how long a device may roam, so please tell us where your devices will operate and we will confirm coverage for those places.

Check before you deploy

Coverage also depends on the device. A modem can only use the networks whose frequency bands and technologies it supports. Before a large deployment, we recommend testing a SIM in your hardware at representative sites, and we are glad to help you plan that.
