Use case — personal, business, international, or family communication
Geographic coverage — does it work outside the UK without extra cost?

Honest Pros and Cons

Sonetel — very cheap for a UK number (from £1/month), with a global app and call forwarding. The setup requires technical steps including SIP configuration. Best for tech-savvy users who want the lowest possible cost.

Zadarma — competitive pricing with strong business features including a PBX system and analytics. Setup is more developer-oriented. Not ideal for non-technical personal users.

Virtual Landline — easy setup, aimed at UK-based consumers who want a landline number forwarded to their mobile. Works well if you are in the UK. International reception may be limited depending on plan.

BluePhone UK — the most expensive option in this table at £15/month. Designed specifically for families living outside the UK who need unlimited incoming calls via a native app. If you only need UK-based forwarding with occasional calls, BluePhone is likely overkill for your budget.

Vonage — a large business-focused provider with enterprise features, number porting and robust support. Pricing at this tier is aimed at teams, not individuals. More than most personal users need.

When BluePhone Makes Sense

You live outside the UK and need to receive calls reliably via app
You need unlimited incoming calls with no fair-use cap
You want a native iOS/Android app with full-screen call UI

When to Choose Another Provider

You are comfortable with SIP configuration and want minimum cost → Sonetel from £1/month
You need business telephony features (PBX, IVR, analytics) → Vonage

Frequently Asked Questions

Which UK virtual number provider is cheapest?

›

Sonetel and Zadarma offer UK virtual numbers from around £1–4 per month, but both require technical setup (SIP configuration). For a fully managed, app-based solution, Virtual Landline starts at £4.50/month and is aimed at personal use within the UK.

Which UK virtual number provider works outside the UK?

›

BluePhone is specifically designed for users living outside the UK. It delivers calls via a mobile app using VoIP, so it works anywhere with an internet connection. Sonetel also supports international forwarding, but requires more technical setup.

Is BluePhone the best UK virtual number provider?

›

BluePhone is not the best choice for everyone. It is priced at £15/month — more expensive than several alternatives. It is designed specifically for families who need unlimited incoming calls and worldwide app-based reception. For straightforward UK-based call forwarding or business use, other providers may be more cost-effective.
