Grok Bot now makes phone calls for you – and cut one Comcast bill from $84 to $45

What's going on

If you've ever spent half an hour on hold with a cable company to cancel a plan or haggle for a discount, you know the pain. Now an AI wants to take that job off your hands. Since November 3, 2026, Grok Bot, the AI agent from Musk's empire, can call businesses in the US for its users. An AI agent is a program that doesn't just answer questions but carries out tasks on its own. Grok Bot navigates phone menus, waits on hold, explains what you want, negotiates and sends you a summary of the call at the end.

Elon Musk announced the feature on X on October 25. The agent could "call someone or a business for you, make a request on your behalf, take notes on the response and send you a summary of the conversation." There were no release notes at the time, and according to the Tesla blog Teslarati, the feature first showed up only in pre-release versions of the app. On November 3, content creator Peter Yang reported that every Grok Bot user could now call US businesses. Musk shared his demo and posted on X: "Try having Grok @Bot make calls!"

The key details at a glance:

How a call works

You tell Grok Bot whom to call and why. According to the terms of service, which business news site PYMNTS reviewed, the agent dials out from a temporary phone number issued by SpaceXSI, SpaceX's AI division. While the call is running, a live transcript appears in the chat, a running record of the conversation. That's how Tesla influencer Sawyer Merritt describes it. Musk shared his demo, which includes the original audio.

If the business asks for something the agent doesn't know, such as an account number or an address, a reply box opens in the chat. You type in the answer and Grok Bot passes it on to the person on the other end. So you stay in the loop without picking up the phone yourself. The AI handles the phone menus, the hold music and the small talk.

First results: discounts, credits, doctor's appointments

The most widely shared clip is Peter Yang's video. In it, his agent calls Comcast and works its way through the phone menu. According to Teslarati, it deflects small talk about the weather by saying it has "no eyes on the sky." It then turns down three upsell offers, attempts to sell it a pricier plan. As leverage, it cites a cheaper fiber offer from rival Sonic. The result: Yang's bill dropped from $84 to $45 a month, and he got a faster connection. That's nearly $500 a year. The call took about 25 minutes. One important detail: before agreeing to the new terms, the agent paused and got Yang's confirmation. The AI did the tedious work, but the human made the decision.

According to Teslarati, other users reported:

• a $100 credit the agent secured after a 51-minute call with Verizon Fios,
• a same-day pediatrician appointment, which Musk also shared.

Not everything worked. One user said a customer service rep refused to cancel a subscription once it became clear an AI was on the line. Marketing site ALM Corp points out that none of this comes from independent testing. The results are posts on X that Teslarati collected, and people tend to post their best examples.

Who's liable? You are

Under the terms of service, every call has to identify itself as a virtual assistant calling on the user's behalf. Calls may also be recorded. PYMNTS spotted another clause: the customer is considered "the caller of record and solely responsible" for every call. That includes complying with laws on telemarketing, robocalls (automated sales calls) and call recording, among them the US Telephone Consumer Protection Act. You also agree to indemnify SpaceXSI against claims arising from your calls. If something goes wrong, you're on the hook, not the provider.

For businesses, PYMNTS says, there's another side to all this: they need to verify who's actually on the line. Fraudsters already use deepfakes and cloned voices to pose as real customers. Voice recognition as a security feature has "already failed," Tim Joslyn, CTO of payments provider Paymentology, told PYMNTS in March.

Expensive to run: hold music eats your weekly limit

The launch comes at an awkward moment. Every Grok Bot subscription comes with a weekly usage allowance. Over the weekend of October 31 to November 1, TechCrunch reports, some subscribers saw their usage meter jump from 50 to 100 percent even though they hadn't run any tasks overnight. Musk confirmed on X that this wasn't a bug:

"The cost of running Grok Bot was unsustainably high relative to revenue."

He didn't say how the limits will change going forward. A call that lasts 25 or 50 minutes, most of it on hold, is exactly the kind of long-running task that burns through your allowance. According to Teslarati, SpaceXSI hasn't explained how calls are counted.

Demand still seems strong, though the user numbers don't line up. Citing Teslarati, ALM Corp puts the figure at more than 600,000 daily active users at the end of October, up from fewer than 100,000 in early September. The product launched around August. PYMNTS, on the other hand, quotes SpaceX President Gwynne Shotwell, who said on the October 20 earnings call that there were 800,000 paying weekly users in early October, more than double the previous month. On the same call, Musk said Grok Bot could eventually take up most of the AI division's compute.

According to Teslarati, Tesla drivers have had the agent in their cars since September 22, and it's enabled in all Cybercabs and Model Y robotaxis. Neither Tesla nor SpaceXSI has confirmed whether you can also start calls from the car.

The competition is dialing too

Grok Bot isn't the first agent to pick up the phone. According to PYMNTS (citing Reuters), Meta gave its assistant Muse a calling feature in September and ran into a problem: many businesses hung up as soon as they realized an AI was calling. Meta then tested having human contractors handle some of the calls and later ended the test. Employees had warned that sensitive data could end up with the contractors.

Google Search has a feature that calls local businesses to check prices and availability. Businesses can opt out. Since September, Google has also been testing "Call for Me" with Pixel 11 owners in the US who have a Gemini subscription, TechCrunch reports. Unlike Grok Bot, Google's feature calls from your own number, and you can take over the call at any time.

ALM Corp offers a comparison that shows how small this market still is: according to AI Agents Store, DoorDash reported only "several hundred" orders placed through external AI agents, out of roughly three million deliveries a day.

The big picture

Handing your annoying phone calls to an AI is no longer science fiction. It's a product paying subscribers can use today. For consumers, that's appealing: cancellations, plan negotiations and appointment bookings cost time and patience, and the agent seems to be pretty persistent. For businesses, it means front desks, phone menus and retention teams have to get ready for AI callers. ALM Corp, for example, advises agencies to set a clear policy for dealing with virtual assistants and to keep discount offers consistent for all callers.

But plenty is still unclear. There are no numbers on how many calls are actually being made, how well it works with small local businesses that don't have long menus, or how many companies turn AI callers away. The success stories are self-reported. The cost question is unresolved, and Musk himself has admitted the service doesn't pay for itself right now. Liability is a concern too: if you let the agent call, you alone are legally responsible. And for now, the feature doesn't work for users outside the US, including in Germany.
