Which network reaches your device?
Drop in the postcode where the SIM will actually live — vending machine, EV charger, IoT sensor, tablet in a van. We'll show all four networks' signal on a map and recommend the data SIM that matches the strongest carrier at that location.

Eight use cases. Same SIM stack.
MBB / data-only is one of the most quietly versatile parts of the business mobile range. Here's what people actually deploy it on.
Tablets + 2-in-1 laptops
iPad / Surface / Galaxy Tab on a 5G data plan. Sign in once, always-connected. No more tethering off the work phone.
Mobile broadband routers
MiFi devices and portable 4G/5G routers — pop-up offices, festival ops, market traders, second homes, building sites without fixed line.
4G/5G failover for fibre lines
Plug into a dual-WAN business router as the secondary path. Card payments, EPOS, voice — all keep working when the fibre takes a hit.
IoT + M2M deployments
Vending machines, EV chargers, smart-building sensors, energy meters, asset trackers. Low-data SIMs from £4/mo, Unlimited M2M £20.82.
Vehicle telematics + dashcams
Fleet trackers, dashcam cloud upload, connected-vehicle infotainment. Designed for the in-vehicle environment with auto-reconnect.
Industrial + remote sites
Building sites, agricultural telemetry, oil-and-gas remote monitoring. Rugged routers + bonded SIMs for sites no fibre will ever reach.
EV charging networks
OCPP-compatible chargers need a network connection for billing + RFID. Low-data SIMs across multiple carriers for redundancy.
Logistics + cold-chain
Temperature monitoring on refrigerated transport, tracker tags on high-value cargo, driver tablets. UK + EU roaming included.
Four carriers. Different strengths.
Which network suits your deployment depends on geography, data profile, and whether you need a private APN. Honest guide — we'll match per-SIM at order time.
Cheapest unlimited tier. M2M Unlimited £20.82/mo. Strong urban 5G + Go Roam to 90 countries.
High-data tablets / hotspots / cloud-upload dashcams
Best rural 4G coverage in the North + Scotland. Reliable for fleet + agricultural telemetry.
Rural M2M / vehicle telematics / cold-chain logistics
Broadest 5G footprint in tier-2 towns. Solid IoT roaming agreements across EU.
Cross-EU fleet, IoT, smart-building
Strongest London + south-east coverage. EE Business has best-in-class private-APN options.
Card-payment failover, enterprise APN, London-centric ops
When the fibre drops,
the till keeps ringing.
Drop an MBB SIM into the secondary WAN of your business router — auto-failover in ~3 seconds when the primary line goes down. Card payments, EPOS, voice, all keep working. Most retail / hospitality sites pay back the £10/mo SIM in a single avoided outage.
Auto-failover ~3s
Dual-WAN router detects primary drop and pivots in seconds.
Card + EPOS stay live
Retail / hospitality outage = lost revenue. SIM = insurance.
Single bill
Failover SIM rolls into the same monthly invoice as the rest of your kit.
Survives any fibre cut
Wholly separate carrier infrastructure to your fixed line.

Three reasons to pick Voice + Data instead.
MBB is great for devices that don't talk. If your device DOES need to talk, you want a V&D SIM (see /business/mobile). Here's the honest cutover.
It's a phone, full-stop
If a human's using it for calls + texts, V&D is what you want. Cheaper per usage profile than MBB + adding voice.
You need unlimited everything
V&D unlimited tariffs at £20–35/mo include unlimited calls + texts + 5G data. MBB unlimited is data-only — no upside for phone use.
You want estate-portal control
Both V&D and MBB SIMs sit in the same SIM Estate Management portal. Mix them freely — same dashboard, same bill.
Volume pricing kicks in at 100 SIMs.
Typical 10–25% off the listed M2M rates depending on data profile. For 1,000+ SIM deployments we model the actual usage profile and quote bespoke. Talk to us before deploying — there's always a better tier than the default.
Real questions, honest answers.
Devices online. Costs predictable.
From a single iPad data SIM to a 1,000-device IoT estate. Talk to us, we'll size the plan to the actual usage profile and quote bespoke for bigger volumes.
