Landline SIM
Put your UK landline number (01/02/03) natively on a mobile SIM or eSIM — no app, no VoIP, no diverts. Creative Filter is a proud ONSIM affiliate.
Overview
A Landline SIM is a regular mobile SIM or eSIM, except the number attached to it is a landline number (01, 02, 03 or 08) rather than a mobile 07 number. Calls in and out use your landline number natively — nothing to dial through, no app to open, no VoIP connection to drop. It's a genuinely different approach to the usual VoIP or divert-based alternatives, and one we recommend to clients who want a business number that isn't tied to a desk or an internet connection. Creative Filter is an ONSIM affiliate — sign-up happens directly through ONSIM, and we're happy to advise on whether it's the right fit before you do.

Frequently Asked Questions
How is this different from a virtual landline or call forwarding?
A virtual landline typically forwards calls to a number you already have. A Landline SIM is different — the landline number lives directly on the SIM itself, so there's no forwarding step and no reliance on another number being reachable.
Do I need an app to use it?
No — it works like a standard mobile SIM. Calls and texts use your phone's normal dialler, not a separate app.
Can I keep my existing number?
Yes, existing landline or mobile numbers can usually be ported across, alongside picking up new numbers if you need them.
Is this suitable for a small team, not just one person?
Yes — additional users and hunt groups (multiple SIMs ringing together) are supported, which makes it a good fit for small offices as well as sole traders.
Do you bill and support this directly?
No — Landline SIM is an ONSIM product, and Creative Filter is an affiliate. Sign-up, billing and ongoing account support are handled by ONSIM directly; we're happy to advise on whether it suits your setup before you sign up.
