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.
5,000+machines we’ve helped

Country life. Connected.
For your phone, your business and the places you call home.

More about your connection
The Three voice and data option currently offered includes unlimited UK minutes, texts and data, subject to its fair-use rules. The mobile broadband option provides unlimited UK data for compatible data devices, with its own service conditions. Both currently have a 30-day minimum term.
Check Three coverage at the intended location and confirm your device is compatible. Unlimited describes the included allowance subject to fair use; it is not a promise of a particular speed or reception everywhere.
These Three plans are for domestic UK use only. Roaming, international, premium-rate and non-geographic services are barred under the current plan information. If travelling or using equipment abroad is important, compare the actual included destinations and charges of a suitable alternative before ordering.
Once your account is ready, your Data-Fi platform provides bills and SIM-management options. We send your account access details separately.
