Virtual phone numbers in 130+ countries

What is a virtual phone number?

A virtual phone number is a real, locally-dialable telephone number that terminates over the internet (via SIP) rather than over a physical copper or fibre line to a specific street address. To anyone calling it, it looks and rings exactly like a normal phone number; behind the scenes, the call is delivered to whatever VoIP system, mobile app, PBX, AI voice agent, or browser softphone you've configured to receive it.

Virtual phone numbers are sometimes called DIDs (Direct Inward Dialing numbers), SIP numbers, VoIP numbers, or cloud phone numbers. The terminology varies by industry; the underlying technology is identical.

Because a virtual phone number isn't tied to a specific location or device, the same number can ring on multiple devices simultaneously, be answered anywhere in the world, be ported between providers, and be paired with software like AI voice agents, IVRs, call recording, or analytics. None of which is possible with a traditional landline.

Types of virtual phone number

All types support voice; most support inbound SMS; capabilities vary by country. The DIDHub catalog tags each number with its capability set (voice / SMS / MMS / fax) before purchase — you never buy a number expecting SMS only to find it's voice-only.

Common use cases

• Local presence for sales and support. A US-based company can have a London 020 number that rings the same desk as their San Francisco 415 number — UK customers see a UK Caller ID, dial as a local call, and convert dramatically better than they would calling a +1 number.
• AI voice agents (Vapi, Retell, ElevenLabs, Bland, Synthflow, LiveKit). Modern AI agent platforms expect a real phone number to be the inbound trigger; DIDHub provides BYOC trunks for every major platform. See the AI agent integrations page.
• Microsoft Teams Direct Routing. Connect virtual phone numbers in 130+ countries to your Teams tenant via DIDHub's managed SBC or your own AudioCodes / Ribbon / AnyNode SBC. Cheaper and broader than Microsoft Calling Plans. Teams Direct Routing details.
• PBX systems — 3CX, FreePBX, Asterisk, FusionPBX, Kamailio, OpenSIPS, Cisco CUCM. SIP trunk drops in via standard ITSP config.
• Two-way SMS. Most virtual phone numbers support inbound and outbound SMS; route inbound to a webhook or email address. Send outbound via REST API or SIP MESSAGE.
• Marketing attribution. A unique virtual phone number per ad/campaign/channel lets you measure exactly which marketing source drives which inbound call. Each number is cheap; granular attribution is the win.
• Number porting. Bring your existing virtual phone numbers from any provider (Twilio, Voxbone, Bandwidth, Telnyx, Plivo, DIDWW, MessageBird, etc.) into DIDHub via standard porting flows. Keep the number, change the carrier. Porting guide.

Pricing

Virtual phone number prices start from $0.50/month on UK geographic and US local NPAs — the cheapest in the market for premium routes — and scale up by country. There are no setup fees on most standard SKUs, no monthly minimums, no contracts, and inbound SMS is free in every country where it's supported.

For a per-country pricing table see the complete buy index or the individual country guides linked from this page.

Per-minute usage (outbound calling, inbound calls on toll-free numbers, SMS sending) is billed separately at carrier-wholesale + DIDHub markup — typically among the cheapest in the market because DIDHub aggregates supply across 8 upstream carriers and routes each call via the cheapest valid path.
