BT One Phone - business landline to mobile
Mobiles that put you and your business in control of every call
The freedom of a mobile, with power of a phone system
If you’re a business that works on the move, or has offices all over the place, making sure everyone’s ready to respond can be tricky. Unless you have BT One Phone.
Take a standard mobile
It starts a bit like a regular phone contract. You’ll get a SIM card to use in your existing handset (or you can choose a new one).
Give it superpowers
With the help of a mobile app and online portal, you can manage all your business mobiles and calls like you would with an advanced phone system.
And get the whole team involved - at a low fee per user
With our range of desk phones, your office-based employees get the same great features. BT One Phone is designed around you, so your bill will be unique, but the average monthly spend is £35 per user, excluding VAT.
BT One Phone in action
Hammersmith-based boutique investment bank, FirstCapital, needed a sophisticated phone system to improve communication with clients all over the world.
From taking important calls on the move to being more in control of the deals they’re working on, see how they’ve massively benefited from having BT One Phone at the core of their business.
Included as standard
Give everyone freedom and control over their business calls.
By managing your calls over a mobile network, you get the flexibility to decide where and when to take them.
Everyone can route their business numbers, including landlines and other mobiles, to their BT One Phone.
Manage features and preferences online.
Set up call routing for your whole business through our online portal. Have a specific number that calls your whole sales team, for example. Or choose who to send calls to when you’re in meetings with presence-based call routing.
It’s easy to set up and remove users, cancel and block SIMs, or change your call routing on the spot.

Your office-based employees can enjoy the same great features.
Whether it’s with extra mobiles or desk phones, give your office-based employees the same clever call management features and connect everyone to the same system. That way everyone’s on the same page (and in the same directory), so it’s all a little easier to manage.

Yes! We’ll design the service to fit the exact way your business works.
We’ll allocate two experts - a BT One Phone voice radio planner and an implementation manager - who’ll assess each of your sites and come up with the ideal configuration.
This includes making sure the dedicated line into your business has the right capacity and resilience to provide the consistent high quality of service you need. We’ll proactively monitor your service on an ongoing basis too, making sure everything is fine-tuned to support current and future call levels. If you need a service boost (e.g. more data capacity), we’ll work with you to provide this in good time.
BT One Phone is backed by advanced disaster recovery measures. Our network is underpinned by fully resilient data centres. These are spread across the country so that if anything ever went wrong at one facility, a second location would automatically keep everything going.
And, because everything’s Cloud-based, your people will always be able to access full office-phone system functionality even if they can’t get into the office - for example, if it's snowing and the roads are a no-go.
With BT One Phone, you get unlimited minutes and you can choose extras like more data, more texts, and roaming extras. Simply add and remove extras to your service when you need them. We also offer flexible payments, allowing you to pay more up front, or spread payments over a longer period.
It should be minimal as we'll provide everything you need as part of our service. We'll come and install a dedicated line into your building. And if you've chosen to have indoor mobile coverage, we may also fit a 'Pico cell' (a small mobile phone base station) to make sure you get excellent mobile signal throughout your premises.
