Questions we get asked
Something else on your mind? Call 020 7112 8558 or send us a message and a telecoms specialist will reply.
Do you cover the whole of the UK?
Yes. Our services are cloud-based and delivered UK-wide, across England, Scotland, Wales and Northern Ireland. Connectivity availability depends on your address, which we check before you order.
Can I keep my existing phone numbers?
Yes. We port local, 0800, 0808 and 03 numbers from other providers and manage the process for you.
How long does it take to get set up?
New numbers can be live the same working day. A phone system with ported numbers typically goes live in one to three weeks, depending on the port.
Do I need to sign a long contract?
Many of our services are available on monthly rolling terms. Longer terms are optional and reduce the monthly price.
What happens when the PSTN closes?
Our services already run on digital networks. We move your lines, numbers and line-dependent equipment across before the 31 January 2027 retirement date.
