ONSIM Virtual Landline

ONSIM Virtual Landline gives UK businesses a professional landline number that rings on their existing mobile — without apps, VoIP software, or broadband dependency. Calls are routed at network level, so they arrive on the user's phone exactly like a standard mobile call. Businesses can choose a new local 01/02 number from over 650 UK area codes, or a national 03 number, and be up and running in minutes. Porting an existing landline number is also supported. Unlike VoIP-based alternatives, ONSIM does not require an internet connection to receive calls. There is no app to install, no Wi-Fi dependency, and no risk of call drop-outs caused by data quality. Calls forward to any UK mobile or landline at network level. ONSIM Virtual Landline starts at £5/month + VAT, making it one of the most competitively priced options in the UK market. Users who also need to make outbound calls displaying their landline number can upgrade to ONSIM Landline SIM from £10/month, which delivers the landline number natively on a SIM or eSIM — no divert required. ONSIM has been operating since 2013, is accredited by the UK Communications Ombudsman, and holds Cyber Essentials certification. The service is trusted by businesses across the UK and in 39 countries. Key features: inbound call forwarding at network level · local and national UK numbers · number porting · no app or broadband required · upgrade path to full Landline SIM · dashboard management · rolling monthly contracts
