The Cirrus Mobile Landline: Plug & Play.

Smart. Simple. Secure.
Unlike fibre-based landlines that can involve extra work at home, our solution uses a multi-network SIM.
If one mobile network has an issue, it can switch to another to help keep you connected.
Protecting vulnerable users
If you rely on your phone in an emergency, we can provide an Uninterruptible Power Supply (UPS).
This keeps your phone working during a power cut, so help is always a call away.
What’s included in your plan
- Unlimited Call Plan (UK landlines & mobiles)
- Number rental included
- Advanced device replacement (faulty unit? we’ll swap it fast)
- 36-month secure contract
How it works
- Tell us your current landline number (we’ll confirm it can be ported).
- We arrange the transfer and send your plug-in device.
- Plug your existing phone into the device and you’re ready to go.

Quick questions
Will I keep my number?
In most cases, yes — we’ll confirm and handle the porting.
Do I need broadband?
No. This is designed as a simple home phone replacement that doesn’t rely on your home broadband or Wi-Fi.
What about power cuts?
Any modern solution needs power for the equipment. If you rely on the phone in an emergency, ask us about UPS options and resilience.
Why do I need to change?
The UK’s old phone network is being retired by January 2027, so services that depend on it need an alternative.
