What is the best WhatsApp chatbot for internet providers in Brazil?
The best WhatsApp chatbot for internet providers in Brazil is the one that answers on the number the provider already uses, with business rules written by you. An AI agent on WhatsApp for an internet provider is an automatic assistant that answers plans, speeds, coverage area and installation lead time with what the provider set up, separates people who want to sign up from people with no connection, collects the account holder's name, address and a description of the problem, and passes the complete ticket to technical support.

What changes at the provider with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered instantly. Here are four everyday situations at the provider before and after the CertuAI agent.

What does a conversation handled by the AI look like?
Example conversation
Provider's AI agent
Customer: Do you have fiber on my street? I live near the neighborhood school
AI agent: Send me the street, the number and a landmark and the team will confirm feasibility.
Customer: Is there an installation fee or a contract term?
AI agent: About installation and contract terms: what you set up.
Is an AI agent or manual service better for internet providers?
The agent wins on repeating tasks, and the person keeps winning on what requires judgment. With manual service, someone at the provider has to stop what they are doing; with the CertuAI agent the answer goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Several subscribers writing at the same time saying the internet is down | The queue jams and people who wanted to sign up wait alongside the ones complaining | Everyone answered instantly, with the notice you wrote and the data collected for support |
| Asks whether there is coverage on their street | Someone in sales stops what they are doing to check | The agent answers based on the neighborhoods you set up and asks for the full address for the team to confirm feasibility |
| Slow internet ticket | The technician calls back to ask for the account holder, address and what is happening | Account holder, address, device lights and time of the problem arrive already written |
| Duplicate bill | Ties up the agent who should be selling plans | The agent answers with the path you set up and alerts billing when a person is needed |
| Prospect who asked about the plan and disappeared | Gets lost among the day's complaints | Becomes a contact in the CRM and gets an automatic follow-up |
What does the WhatsApp agent do for internet providers?
It does the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers subscribers your way, with your rules.
Plans and speeds
Fiber, radio, residential and business plans, what each one includes and which have a contract term, the way you set it up.
Coverage by neighborhood
The agent answers based on the service areas you wrote and collects street, number and a landmark for the team to confirm feasibility.
Support triage
No connection, slow speed, Wi-Fi password change or change of address: each topic kept separate and passed to the department that solves it.
Technical ticket intake
Account holder, address, device lights, since when it has been happening and what has already been tried, in a single conversation.
Installation scheduling
Day and time slot agreed in the conversation, within the calendar you defined, and recorded on the contact.
What questions do subscribers send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday provider messages no longer depend on you having your phone in your hand.
How does the agent start answering at the provider?
In three steps, the same day. No installation, no code and without changing the number subscribers already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.

Create my agentWhat needs to be ready before turning on the agent at the provider?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The plans with their speeds, what each one includes, installation fee and contract term rules
- The list of neighborhoods and areas served and what to answer when the street is on the edge of coverage
- The basic step by step the subscriber can do alone before opening a ticket
- What support needs to receive in a ticket: account holder, address, device lights and since when it has been happening
- The path to a duplicate bill and the hours billing and support are available
Who updates the outage notice in the Brain when the network goes down and how quickly that happens, including at night and on weekends.
The most common mistake: Letting the agent promise a time for the connection to come back. It cannot see the network, and a time given without basis becomes the next complaint. The right approach is for it to repeat only the notice the technical team wrote and to log who reported the problem.
Frequently asked questions from internet providers
Does the agent know whether the network is down in my neighborhood?
No. It cannot see the network or each subscriber's signal. When you know of an outage, you write the notice in the Brain and the agent starts answering with it. Otherwise, it collects the account holder, address and what is happening and hands it to support.
Does it look up the provider's system to check the subscriber's bill or plan?
No. The agent does not connect to the provider's management system. For a duplicate bill it answers with the path you set up, such as the link to the subscriber portal, and calls billing when the person cannot do it alone.
Can it walk the subscriber through restarting the device before opening a ticket?
Yes, if you write the step by step. It passes along exactly the basic guidance that is in the Brain, records whether it worked and, if it did not, builds the ticket for the technician. It does not invent a diagnosis.
How does it answer whether there is coverage at an address?
Based on the neighborhoods and areas you set up. For a street on the edge or a new area, it does not confirm on its own: it takes the full address and passes it to the team to check feasibility before promising an installation.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?

In short
Answers plans, coverage by neighborhood and installation lead time, and collects the details of customers with no connection for support. Every conversation becomes a contact in the CRM.
