SIM features
What a Sturdy SIM gives your devices.
Coverage on more than 200 networks, failover between them, one flat price, and a service made for machines. Here is what each feature means, in plain language.
Coverage
Nationwide coverage
Access to the major networks across the United States from the same card.
Worldwide roaming
The same SIM connects on carrier networks abroad, so equipment can be shipped or can travel.
Rural and indoor reach
A better chance of a usable signal in places where one carrier alone falls short.
5G and LTE-M
5G for devices that need speed, LTE-M for small low-power devices, and standard LTE.
Reliability
Network failover
When the network in use is lost, the device can register on another that is in range.
No single carrier to depend on
An outage at one carrier does not have to take your equipment offline.
No SIM swaps
The alternative networks are already on the card, so nobody has to visit the site.
100% reliability guarantee
Because the SIM draws on multiple carriers, we guarantee 100% reliable connectivity.
Pricing & account
One flat price
A single price for the service, whichever network the device uses.
No rate card
No table of carriers, zones, and roaming surcharges to work through.
One account
Every SIM you own on one account, with one bill.
No carrier contracts
One agreement with Sturdy SIM in place of one with each carrier.
Built for devices
Data-only service
A data connection for machines, with no voice service attached.
Unattended operation
Intended for equipment that runs without a person present.
Routers and gateways
Primary or backup internet for sites, vehicles, and temporary locations.
Trackers, sensors, and terminals
Suited to the small, regular transmissions that connected devices make.
Deployment
One SIM for every unit
Fit the same card to every device, wherever it is going.
Every SIM size
Standard (2FF), micro (3FF), nano (4FF), and embedded (MFF2).
Trial SIMs
Test in your own hardware before committing to a rollout.
Compatibility review
We check your device and its supported networks before you order.
No 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.
