About

Dial is a communication stack for AI agents that gives software its own real phone identity: a number it controls to place and receive voice calls, send and receive SMS, and message over WhatsApp through one REST API, MCP server, CLI, or SDK. It rebuilds a telephone stack originally designed around humans, SIM cards, carrier contracts, handsets, and verification flows so autonomous agents can communicate without dedicated hardware or manual carrier setup. Agents can provision a real phone number, make AI voice calls that follow instructions such as booking, confirming, or following up, and use live transcription with optional transfer to a human. Dial also supports two-way SMS and WhatsApp messaging, inbound calls and texts, AI receptionist behavior, and streamed inbound events. Agents can receive SMS verification codes for phone-gated workflows and react to communication events programmatically.

Pros & Cons from Real Users

Pros

  • Fast processing, fast human support answers. Ability to renew a phone number for free if target service can't send an SMS to it.
  • Charges are canceled or refunded instantly if no verification code arrives within the allotted window
  • out of the dozen or so numbers I've requested for Telegram and Threads. the code arrival rate has been high.
  • What pros should I write? it is nothing pro about this website, or from their services. You should remove this part.
  • The cost per activation is suoer low compared to most main competitors look like SMS-Activate or OnlineSIM

Cons

  • Primitive bot at the start of the conversation, but switching to human is very fast.
  • Some strict platforms occasionally block specific sub-ragers of virtual or VOIP numbers.
  • it's built almost entirely around quick 15-minute OTP activations. If you need a long-term dedicated virtual line to hold for months for ongoing re-verifications, this isn't the right tool.
  • Be aware, they offer inexistent numbers.
  • No long term rental feature. Herosms is currently built almost entirely around short term activations
