Keep your staff connected to your business.

Custom-fit bundles.

Choose your own contract length, minutes, data and mobile network. Our mobile specialists will use your current bill to help craft a contract that works for you, with the flexibility to change if your business does.

We’ll keep on top if it.

Your dedicated Account Manager will be by your side from day one. They’ll create a series of alerts to help you keep a track of usage and any anomalies in activity, avoiding unnecessary charges. And if they think you could be getting a better deal, they’ll put the option to you.

Take your phone anywhere.

If you’re planning to work overseas, we can access preferential tariffs and roaming charges. Don’t struggle for a connection abroad or come home to an unexpected bill.

Coverage where you work.

By partnering with the major networks around the UK, we can recommend the best network for your area. Our mobile specialists work hard to make sure our customers have the best possible coverage wherever they operate.

Do it all through the internet.

At F One we can provide you with a data SIM so you can use your devices to access the internet wherever you are. It’s our business to make sure your business has consistent connectivity, however it is you’d like to communicate.
