About Data-Fi
From the farm to family life, we make finding your connection feel simple.
Find your SIMOur story
We spent years helping farmers connect their tractors and equipment. Along the way, we learnt what it takes to keep rural life connected.
Then our customers began asking: could we help with their phones, their families and their businesses too?
That’s how Data-Fi grew — through people who knew us, trusted us and wanted the same straightforward help in the rest of their lives.
Grounded in rural life
From the kitchen table to the farmyard, the office to the open road, we understand that one connection has a lot to do.
We take the time to understand where you are and what you need, then help you choose a network and plan that fit. Clear advice, in plain English.
“You understand us, you know what we need, you make it simple and it just works.”
Rural roots. Global reach.
Our work has taken us beyond the UK, supplying SIMs to machinery dealers around the world. Today, we bring that same practical experience to your phone, your business and your connected equipment.

More about your connection
Our O₂ voice and data options include UK calls with a choice of monthly data allowances. The mobile broadband range provides a separate choice for compatible routers and tablets. The plans currently offered have a 30-day minimum term.
Check coverage at the locations you rely on and confirm that the tariff supports your device and intended use. Review the included allowance, any fair-use rules and out-of-bundle charges rather than treating a monthly price as the whole decision.
EU Roam Like Home is included for the O₂ plans in this catalogue, within the listed roaming zones and the selected plan's data limit. The roaming allowance forms part of the monthly data allowance; it is not an extra separate pot. Other destinations and additional services can cost more.
Your own Data-Fi platform lets you view bills and manage your SIM services after your account is set up. We email the access details separately.
See phone SIM options, learn about mobile broadband, or ask us to check a device or destination.
