IoT SIMs that don't get stuck on a weak network

One SIM reaches 730 networks in 203 countries, including all 4 UK mobile networks. Where one network is weak, the device can attach to another. Every connection attempt is visible from your desk, and data is billed per megabyte with no bundles to pre-buy.

How it works

The device picks the strongest network where it is

Most roaming SIMs are steered: told to stay on a partner network even when it is down to one bar. Ours carry no preferred list. The modem attaches to the strongest network in range, and you can still restrict the choice with network lists when you need to.

One SIM, all 4 UK mobile networks

A single-network SIM goes dark wherever its one network is weak. Ours can attach to every UK mobile network, so a van, tracker or terminal uses whichever is strongest where it stands.

Live = in commercial service. Validated = independently tested and proven to work, but not covered by the service level agreement. 3G has been switched off across the UK. Every other country is in the coverage explorer.

Worked example (illustrative)

A distributor with 300 vans and 2,000 pallet trackers

How one UK distribution business would run on VoicePro IoT. It shows how the service works; it is not a customer story.

The vans

Routers and card terminals in each van use industrial-grade removable SIMs on 4G. On a rural route where one network fades, the router attaches to another UK network, so orders, stock checks and card payments carry on.

The trackers

Battery trackers on high-value pallets use embedded MFF2 chips on LTE-M, with the power-saving modes designed for multi-year battery life. When a pallet crosses into Europe, the same SIM attaches to local networks with nothing to change.

The control room

SIMs are grouped by vans, trackers and depot, each group with its own data limit and network list. A tracker that stops reporting shows up in the network log with the reason, before anyone drives out to it.

The bill

One invoice. Data is billed per megabyte, with usage visible in your VoicePro portal and through the API.

Why VoicePro

Who you are buying from

A UK company, a UK contract

Your contract, your invoice and your point of contact sit with VoicePro Plus, a London-registered telecoms company.

A telecoms operator, not an app

VoicePro also runs carrier voice, SMS and numbering for operators, so your devices sit with a business that already carries traffic for other networks.

Phones and devices, one supplier

The same operator behind VoicePro Mobile for Business, so your team's phones and your fleet's devices can sit with one supplier.

Getting started

Test it in parallel, then scale

Nothing about your hardware has to change to find out whether it works better.

1. Test free

A free trial: 30 days, 5 SIMs and 50 MB of data across 440+ networks, with the management platform and email support. Run the SIMs alongside your current provider, on your own routes and sites.

2. Compare

Look at attach success, coverage gaps and data use side by side, in the network logs rather than on a supplier's word.

3. Scale

The settings, groups and integrations from the trial carry straight into the full fleet. Nothing is rebuilt.
