How to text ChatGPT, Claude and Grok: every real way, phone number included

By the AgentMsgr team · Updated November 13, 2026 · 10 min read

Can you text ChatGPT? Sort of. In the US and Canada you can call 1-800-ChatGPT (1-800-242-8478) for free, 30 minutes a month, but there's no plain text-message line. Messaging that number on WhatsApp works again only for phone numbers in Europe's EEA, and a limited number of Pro users in the US, Canada and Mexico can now text a ChatGPT dot. Claude has no phone number or WhatsApp chat at all, and Grok lives in X and its own app. Here's every real way to reach each one, as of November 2026. To text agents like a ChatGPT dot, a Grok Bot and a Meta Muse from one app, that's what AgentMsgr does.

Can you text ChatGPT? The phone number, WhatsApp and SMS

OpenAI gives you three ways to reach ChatGPT from a phone without opening the app. Which one you get depends on where your number is from.

The ChatGPT phone number: 1-800-ChatGPT

Call 1-800-CHATGPT, which is 1-800-242-8478, from a US or Canadian number and you talk to ChatGPT out loud. You don't need an account. OpenAI's help page says you get 30 minutes a month for free, it warns you as you get close, and your carrier's normal fees may apply. You have to be 13 or older.

It's a voice line, though, not a texting line. OpenAI calls it an experimental feature, and it stores calls and their transcripts for a limited time for safety and abuse checks. One tip from OpenAI that's worth following: call from somewhere quiet, because background noise can make it answer things you didn't ask.

ChatGPT WhatsApp: back in Europe, not in the US

ChatGPT on WhatsApp has had a bumpy year. OpenAI announced on October 21, 2025, that a change to WhatsApp's rules meant ChatGPT would leave WhatsApp after January 15, 2026, and it asked people to link their accounts to keep their chat history.

Then on July 13, 2026, OpenAI brought it back, but only in the European Economic Area (the EU plus Iceland, Liechtenstein and Norway). You message the same verified contact, +1-800-242-8478, on WhatsApp. You can send text, images and voice notes, ask for pictures, and write in many languages. You don't need an account, though linking one raises your limits.

What counts is your WhatsApp number's country code, not where you're standing. A US number still won't work, even in Paris. OpenAI's release notes also say ChatGPT is on Kakao in South Korea and on Viber in supported markets.

ChatGPT SMS: texting a dot instead

There's no ChatGPT SMS number you can text. The closest thing is new. On October 28, 2026, OpenAI started a beta that lets Pro users text their dot, its always-on agent, and its help page (updated November 11) now lists a limited number of Pro users in the US, Canada and Mexico. You open the dot's profile in ChatGPT and choose Texting. It runs through Apple's Messages app on an iPhone or RCS on an Android phone; plain SMS isn't listed.

Only you can text your dot, and it can text you first with updates. OpenAI says it can't see your other text conversations, and that a third-party company called Linq carries the messages. A dot comes with ChatGPT Pro, which starts at $100 a month; the details are in what ChatGPT dots are.

How to text Claude: the apps, and what Anthropic doesn't offer

If you want to text Claude, you can't, not the way you text a person, unless you're a developer running Claude Code (below). Anthropic's help center (updated August 6, 2026) lists five ways to reach Claude: claude.ai in a browser, the iPhone app, the Android app, the desktop app, and its developer platform. There's no phone number to call or text.

Claude WhatsApp and Claude SMS: neither comes from Anthropic

Search for a Claude WhatsApp number and you'll find businesses that plug Claude into WhatsApp through Anthropic's developer tools. Those are their products, not Anthropic's, and they see everything you send. The same goes for any "Claude SMS" service. If one asks for your email or bank logins, think twice.

Text Claude Code from Telegram, Discord or Apple's Messages app (for developers)

Developers do get an official way in. Claude Code, Anthropic's coding tool that runs on your computer, has a research preview called Channels. Messages you send from Telegram, Discord or Apple's Messages app on a Mac land in your running Claude Code session, and Claude answers in the same chat. For Telegram or Discord you make your own bot and install a plugin. The Messages channel needs macOS and reads your Messages app directly, so there's no bot to make: you text yourself.

The catches are big for anyone who isn't a developer. Messages only arrive while Claude Code is running, setup happens in a terminal, and on Team or Enterprise plans an owner has to switch Channels on first. For everyday use, the Claude phone app is the way.

How to text Grok: X, the Grok app and Grok WhatsApp questions

Grok, the chatbot from SpaceXSI (formerly xAI), lives in three places: grok.com, the Grok app for iPhone and Android, and inside X. On X, you tap the Grok icon in the navigation bar and start typing. You can also add @Grok as a member of an X Chat group conversation, the closest thing to a group text with Grok in it. X's help page notes that once Grok is in a group, X and SpaceXSI can see every message sent there until it's removed.

Grok WhatsApp and Telegram: not listed by SpaceXSI

People search for Grok WhatsApp and Grok on Telegram a lot. Neither SpaceXSI's Grok docs nor X's help page lists WhatsApp, Telegram or a text-message number for Grok. If someone hands you a "Grok number," treat it with suspicion.

How to text Grok Bot in X Chat

Grok Bot is a different product: AI teammates with their own computer in the cloud. You can message your Bots in the Grok Bot app for desktop, iPhone and Android, and also in X Chat, in the X app or on x.com, where they're the same Bots you use in the app. You need a plan that includes Grok Bot, which on The X Subscription means Premium, Super or Ultra (Plus doesn't count). Your Grok account also has to be connected to a Cursor account, and it isn't available for company email accounts.

Bots also work in Slack, and each account can claim one email address at mail.grokbot.com. SpaceXSI's docs don't mention Telegram, WhatsApp or SMS for Grok Bot. The full list is in where you can message a Grok Bot.

How to text Meta Muse, Meta's personal agent

If you want to text Meta Muse, you have more choice than with the others. Muse runs in the Muse app, at muse.ai, and in WhatsApp. WhatsApp's help page says you can chat with your Muse agent there, though only in some countries so far. In WhatsApp, Muse sees only its own chat with you, plus anything you choose to forward it, and it comes with a free usage limit. Muse's free plan next to ChatGPT's dots is compared in Meta Muse vs ChatGPT.

Where should you talk to it day to day? We cover that in the Meta Muse app vs a texting thread.

Texting ChatGPT, Claude or Grok from your phone: pick yours

Choose the assistant and your phone. You'll get the simplest way to text or message it, and what it can't do that way.

Whichever you pick, you'll be reading answers on a small screen. A first message like this one keeps them short and useful:

A first text for any assistant on your phoneI'm texting from my phone, so keep answers under 80 words unless I ask for more. Use plain sentences, no tables. If my question isn't clear, ask me one short question instead of guessing. First question: what's one thing you can do for me by text that a quick web search can't?

Prefer an assistant made for texting? Instinct, an assistant you text, is one, and Poke alternatives compares five.

Text your agents in one app, with your own Claude or ChatGPT chiming in

We make AgentMsgr, so here's where it fits. Everything above is one assistant in one place. AgentMsgr is a texting app for the agents you already run, like a Grok Bot or a Meta Muse (the two we use daily) or a Hermes agent you host. They sit in one chat list: text one of them, or put several in a group where each reads what the others said.

The assistant you already talk to can take part too. Connect your own Claude, ChatGPT, Grok or Perplexity to AgentMsgr as yourself, and it can post into one of your chats and read the replies back, so a plan you worked out with Claude can go straight to your agents.

It isn't SMS, and there's no phone number. Agents connect directly, with email as the backup, and things like voice, settings and purchases stay in each agent's own app. A Grok Bot wakes through a routine's webhook, which is one setup step inside Grok Bot.
