One IoT SIM for every device and every market
Most fleets end up with a drawer of different SIMs: one per country, one per network, one per device type. This is one SIM that reaches 730 networks in 203 countries on 2G, 3G, 4G, LTE-M and NB-IoT, in the form your hardware needs: a removable card, a chip soldered to the board, or software on the radio module.
Three forms, one network behind them
Removable SIM card
The triple-cut card (2FF, 3FF and 4FF) for routers, gateways, trackers and anything with a SIM tray. The quickest way to test, and the easiest to fit across an existing fleet.
Embedded chip (MFF2)
A 5 x 6 mm chip soldered to the board. Nothing to remove, steal or shake loose. Industrial grade as standard, and available with eSIM multi-profile capability.
SoftSIM
No physical SIM at all: the SIM runs in software inside supported radio modules. The tray and a line on the bill of materials disappear, and one firmware image ships to every market.
Against the SIMs most fleets start with
| Consumer phone SIM | Single-network IoT SIM | VoicePro IoT SIM | |
|---|---|---|---|
| Networks | One home network, roaming abroad | One network | 730 networks in 203 countries |
| Which network | Chosen by the operator | Fixed | The strongest in range; restrict it with network lists if you want |
| LTE-M and NB-IoT | Rarely provisioned | Depends on the network | Yes, wherever the local network offers them |
| Temperature rating | Consumer grade | Varies | Commercial -25 to +85°C, or industrial -40 to +105°C |
| Configuration | Roaming terms per country | One market only | One global APN, the same everywhere |
| Built for | People and phones | One market | Machines in many markets |
Commercial or industrial, chosen by environment
| SIM type | Size | Architecture | Commercial grade | Industrial grade |
|---|---|---|---|---|
| Removable card | 2FF, 3FF, 4FF | UICC or eUICC | -25°C to +85°C, 10-year data retention | -40°C to +105°C, 15-year data retention |
| Embedded chip (MFF2) | 5 x 6 mm, soldered | UICC or eUICC | Not offered (ships industrial) | -40°C to +105°C, 15-year data retention |
| SoftSIM | Software on the module | UICC, in software | Set by your radio module | Set by your radio module |
Choose industrial grade for vehicles, outdoor cabinets, cold chain and plant, where temperature swings and vibration would shorten the life of a commercial card.
What your engineers will ask
Which SIM for which device
| Device | Choose | Why |
|---|---|---|
| Van router, card terminal, gateway | Removable card, industrial grade | Quick to fit, rated for vehicles and outdoor kit |
| Battery asset tracker | MFF2 chip on LTE-M | Sealed and tamper-resistant, with power saving for multi-year life |
| Smart meter or fixed sensor | MFF2 chip on NB-IoT | Reaches deep indoors and draws the least power |
| A product you manufacture at volume | MFF2 with eSIM, or SoftSIM | One SKU for every market, and the operator stays your choice |
| Pilot or prototype | Removable card | Fastest to test; move to an embedded form later on the same network |
Common questions
Will these SIMs work in my existing hardware?
Yes, in any cellular router, gateway, module or tracker that supports the radio technology you need. SoftSIM needs a supported radio module.
Can the SIMs make calls?
No. They are machine SIMs for data and SMS, with no phone number and no voice service. For your team's phones, see VoicePro Mobile for Business.
What does non-steered mean in practice?
A steered SIM is told to prefer a partner network even when a stronger one is in range. Ours carry no preferred list, so the modem picks the best network at each location. In the UK that can be any of EE, O2, Vodafone or Three.
What happens as 2G and 3G switch off?
The coverage explorer shows each network and technology by country, so you can design around 4G, LTE-M and NB-IoT. The SIM and the platform stay the same when a device moves to a newer radio.
