HOW-TO GUIDE

How to Receive UK Landline Calls on Your Smartphone

Receiving calls on a UK landline number via smartphone is possible through VoIP technology. You get a real 01/02 number that rings an app on your phone — no physical line, no landline socket, no home router required.

Step-by-Step Setup

1

Get a UK virtual landline number

Subscribe to a VoIP provider that issues UK geographic (01/02) numbers. With BluePhone, you subscribe online and a number is assigned within a few hours. You will receive the number by email.

2

Download and log in to the app

Install the provider's app on your iPhone or Android. Log in with the credentials you created during signup. The app registers your device as the destination for calls to your number.

3

Share your number

Give your new UK landline number to whoever needs to call you. For prison calls, give the number to your loved one so they can add it to their approved PIN list at the prison.

4

Receive calls anywhere

When someone dials your UK number, the call arrives on your phone via the app — just like a regular incoming call. Works on WiFi or mobile data, anywhere in the world.

iOS and Android Compatibility

Modern VoIP apps work on both platforms:

WiFi vs Mobile Data

VoIP calls work on any internet connection. A voice call uses approximately 0.5–1 MB per minute — even a weak 4G connection handles this easily. WiFi at home or in a café works equally well.

The only scenario where calls may fail is complete loss of internet connection — for example, in a tunnel or a remote area with no signal. In that case, the call simply goes unanswered.

Reliability

VoIP call reliability depends primarily on your internet provider and the VoIP provider's infrastructure. BluePhone routes calls through Telnyx, a carrier-grade network with data centres across Europe. In our experience, connection reliability on a normal home broadband or 4G connection is comparable to a standard mobile call.

Frequently Asked Questions

Can I receive UK landline calls on my iPhone?

›
Yes. Apps like BluePhone use VoIP technology to deliver UK landline calls to your iPhone via the internet. The call appears as a full-screen incoming call, even when your screen is locked. You need an internet connection — WiFi or mobile data — to receive calls.

Does receiving UK landline calls via app work on Android?

›
Yes. Android devices are fully supported. The app receives calls using push notifications to wake the device when a call arrives, then connects the VoIP audio stream. Call quality depends on your data connection.

Will I receive calls if I have no WiFi but I have 4G?

›
Yes. VoIP calls work over any internet connection — WiFi, 4G or 5G. Mobile data is sufficient to maintain a clear voice call. Very weak signal (1 bar of 2G) may cause quality issues, but standard 4G is more than adequate.

Is there a delay on VoIP calls compared to regular calls?

›
On a good internet connection, VoIP call latency is typically under 150 milliseconds — imperceptible in normal conversation. On a slow or congested network, you may notice a slight delay. BluePhone uses Telnyx carrier infrastructure which is optimised for low latency.
