Why Compare?

Comparing all four networks side by side reveals whether you are getting good value or paying more than you need to.

Frequently Asked Questions
What is the difference between VoIP and a virtual landline?
VoIP (Voice over IP) is a complete phone system that makes and receives calls over the internet using desk phones or apps. A virtual landline is simply a geographic phone number that forwards incoming calls to your mobile or landline. VoIP replaces your entire phone system; a virtual landline just gives you an additional number.
Which is cheaper, VoIP or virtual landline?
A virtual landline is cheaper, typically approximately £11+VAT-10 per month for a number with call forwarding. VoIP systems cost approximately £11+VAT-25 per user per month but include much more functionality. For sole traders who just need a professional number, virtual landline is more cost-effective. For businesses needing a full phone system, VoIP offers better value.
Do I need VoIP or a virtual landline?
Choose a virtual landline if you just need a local geographic number that rings on your mobile. Choose VoIP if you need multiple extensions, call queues, auto-attendant, call recording, or a full office phone system. Sole traders and freelancers typically need virtual landline; offices with 3 or more staff typically benefit more from VoIP.
Can I have both VoIP and a virtual landline?
Most VoIP systems include virtual numbers as part of the package, so you would not need both separately. If you have a VoIP system, you can typically add local geographic numbers to it. If you only have a virtual landline and later need a full phone system, you can usually port the number to a VoIP provider.
