AI phone numbers

Phone numbers for AI agents, built on quality mobile connectivity

AI agents are only as useful as the communication rails behind them. IO Simplicity provisions mobile-provider-backed numbers with SMS, voice, eSIM, and SIP options designed for practical, reliable customer communication.

  • Quality mobile-provider routes, not the cheapest available path
  • Two-way SMS for real conversations and verification flows
  • SIP-ready voice for AI voice systems and contact centers
  • eSIM data when the same program also has devices in the field
Capabilities

What an IO Simplicity number program includes

Everything an AI platform needs to communicate over real mobile rails — messaging, voice, verification, and the provisioning structure behind it.

Mobile-provider numbers

Numbers sourced through mobile-provider connectivity instead of flimsy, low-quality routes.

Two-way SMS support

Send and receive messages so your agents can hold a real conversation, not just blast alerts.

SMS deliverability focus

Route quality and sender setup handled with deliverability in mind from the first message.

SIP-ready voice workflows

Route calls into AI voice systems, contact centers, or your existing communication platform.

eSIM & data capabilities

Add flexible eSIM data connectivity wherever devices or field hardware are part of the workflow.

Number programs at scale

Provisioning and program structure for AI platforms managing numbers across many customers.

Use cases

Where AI phone numbers do the work

Support, sales, scheduling, verification, and voice — all on numbers chosen for delivery performance rather than lowest cost.

AI customer support agents

Inbound help over SMS and voice, backed by real mobile numbers.

AI sales outreach & follow-up

Conversational follow-up that reaches the inbox it's meant for.

Scheduling & reminders

Appointment confirmations, reschedules, and reminder flows.

Verification & OTP messaging

Time-sensitive codes on routes chosen for reliable delivery.

Voice assistants & SIP call flows

SIP trunking into AI voice systems and call routing logic.

Connected-device alerts

Notifications from field devices into the same messaging stack.

How it works

From workflow to live numbers in three steps

We map how your agents message and call, which regions they cover, and what volume looks like.

Provision quality numbers

Mobile-provider-backed numbers configured for two-way SMS, voice, and verification traffic.

Scale the number program

Add numbers, regions, and customers without renegotiating how the whole program works.
