The good news? It’s simpler than you might think. You likely already have everything you need at home – a broadband connection and your existing analogue phone. With a Voipfone subscription and a plug-and-play VoIP adapter, you can be up and running in minutes.

Start Your Free TrialWhat You Need to Switch to VoIP
Switching to VoIP is surprisingly straightforward. Here’s everything you need to get started:
Broadband Internet Connection
VoIP calls travel over your internet connection. Any standard UK broadband will work perfectly – you don’t need fibre, though faster speeds do help with call quality. Even basic ADSL provides more than enough bandwidth for crystal-clear VoIP calls.
Tip: A VoIP call uses approximately 100kbps – far less than streaming video.
Your Existing Analogue Phone
Here’s the best part – you can keep using the phone you already have at home! Whether it’s a classic corded phone or a wireless DECT handset, your existing analogue phone works perfectly with VoIP when connected through an adapter.
No new equipment needed: Your familiar phone, same great experience.
Plug-and-Play VoIP Adapter
A VoIP adapter (also called an ATA) is a small device that connects your traditional phone to your internet router. It converts your voice into digital signals that travel over the internet. Voipfone adapters come pre-configured – just plug in and start calling.
From just £52: One-time purchase, 3-year warranty included.
Voipfone Subscription
Choose from a range of affordable plans starting from just £5 per month. All plans include essential features like voicemail, call forwarding, and the Voipfone softphone app. No contracts – switch or cancel anytime.
30-day free trial: Try before you commit, risk-free.
Step-by-Step Guide: Moving to VoIP with Voipfone
Follow these simple steps to make the switch to VoIP. Most customers are up and running within 15 minutes of receiving their adapter.
1 Check Your Broadband Connection
Before you start, ensure you have a working broadband internet connection. VoIP works with any internet service provider – you don’t need to switch to Voipfone broadband (though we do offer excellent fibre packages if you’re interested).
Minimum requirements: 1Mbps upload/download speed per active call. Most UK broadband connections easily exceed this.
2 Choose Your Voipfone Plan
Select the plan that best suits your calling needs. All plans come with no contracts – you can upgrade, downgrade, or cancel at any time directly from your online control panel.
All prices exclude VAT. All plans include voicemail, call forwarding, business hours routing, and the Voipfone softphone app.
3 Get Your VoIP Adapter
Choose a plug-and-play VoIP adapter from Voipfone. All adapters come pre-configured with your account settings – no technical knowledge required. Simply connect to your router and plug in your phone.

Will VoIP work if my internet goes down?
VoIP requires an internet connection to work. However, you can set up call forwarding to automatically redirect calls to your mobile phone if your internet is unavailable. This is configured easily through the Voipfone control panel.
Can I call 999 with VoIP?
Yes, you can call emergency services (999 and 112) with Voipfone. We’re a fully licensed UK telecommunications provider registered with Ofcom. Your address is registered with the emergency services database.
Do I need to change my broadband provider?
No, Voipfone works with any broadband provider. You can keep your existing internet service and simply add Voipfone for your phone service. We also offer our own fibre broadband packages if you’d prefer everything from one provider.
How long does it take to set up?
Once you receive your pre-configured adapter (typically 2-3 business days), setup takes just minutes. Simply connect the adapter to your router, plug in your phone, and you’re ready to make calls. If you’re porting your number, that process takes 10-14 working days.
Is there a contract or minimum term?
No, all Voipfone plans are contract-free. You can upgrade, downgrade, or cancel at any time directly from your online control panel. We believe our service quality keeps customers – not contracts.
