No-landline vs landline personal alarms
A landline is no longer the default. Many households use broadband only or a mobile phone, and that changes which alarms will work. The right answer depends on coverage and how the device connects.

Side by side
| Decision | No-landline alarm | Landline alarm |
|---|---|---|
| Connection | Mobile network, home broadband, or both | Traditional phone socket |
| Portability | Some devices work outside the home | Usually limited to the home and garden |
| Power cuts | Battery backup varies; mobile devices may keep working | Often stops unless the base has backup |
| Coverage risk | Depends on mobile or broadband reliability | Depends on the phone line staying active |
| Best when | You have no landline or want outdoor coverage | You have a reliable landline and want a simple setup |
Choose no-landline alarm if...
- You have cancelled your landline or moved to broadband-only
- You want an alarm that works in the garden or on the move
- You are willing to check mobile coverage at your address
Choose landline alarm if...
- You have a working landline and no plans to remove it
- You want the simplest possible installation
- Mobile coverage at your address is poor and broadband is unreliable
Bottom line
Check the connection at the address, not just the town. Ask what happens during a power cut, and confirm whether the plan includes the SIM or data. A no-landline alarm is only better if the connection is reliable where you live.
