When does my Telmex service actually stop after I cancel?

Service is typically deactivated within 24 business hours after you return your equipment and sign the cancellation form at a service center. Some users report a gradual speed reduction over a few days rather than an immediate cutoff. To avoid being billed for another month, complete the full process (phone call + in-person visit) at least 5 days before your next billing date.

Can I get a refund for days I already paid for but won't use?

Telmex does not issue prorated refunds for unused days within a billing cycle. Cancellation is free as long as you have no outstanding balance and return equipment in good condition, but you will not be reimbursed for the remainder of a paid period. If you have an overpayment credit on your account, contact Telmex at 800 123 2222 to request a refund of that specific credit.

Can I reactivate my Telmex service after cancelling?

Yes, you can request a new Telmex contract after cancelling. However, reactivation is treated as a new customer sign-up — your previous account, phone number (unless ported), and plan terms are not automatically restored. Visit a Telmex Centro de Atención or call 800 123 2222 to request a new installation.

Can I keep my phone number when I leave Telmex?

Yes. You can port (portar) your Telmex landline number to another provider before or after cancellation through Mexico's number portability program. Contact your new provider to initiate the port — they will handle the process. Do not cancel your Telmex service before porting, as you may lose the number.

Do I have to pay a cancellation fee or penalty?

No. Telmex does not charge a cancellation fee or impose a mandatory contract commitment period. Cancellation is free as long as you: (1) have no outstanding unpaid balance, (2) return the modem and all Telmex-provided equipment in good working condition, and (3) have no active Tienda Telmex store credits or Inbursa loan tied to your account. Damaged or unreturned modems may incur a charge.

What happens to bundled services like Netflix or Dish after I cancel Telmex?

Bundled third-party services (Netflix, Claro Video, Dish, etc.) are NOT automatically cancelled when you cancel your Telmex service. You must cancel each of these separately through their own platforms or customer service channels. Failure to do so will result in continued billing from those providers even after your Telmex internet and phone are deactivated.

Método Cancelar:Phone

Call Telmex customer service

Call 800 123 2222 from any phone, or dial *2222 from your Telmex landline. When the automated system answers, press 1 if calling from the Telmex line you want to cancel, or press 2 if calling from a different number (you will then be asked to enter your 10-digit Telmex number).

Navigate the phone menu

From the main menu, select option 5 ('Cambio de domicilio y otros servicios' / Change of address and other services), then select option 2 ('Otras gestiones' / Other transactions). Wait to be connected to a live representative.

Request cancellation ('baja de servicio')

Tell the representative you want to cancel your service: 'Quiero dar de baja mi servicio.' Specify whether you are cancelling internet, phone line, or both. The representative will ask for your reason — providing one is required to proceed.

Decline retention offers

The representative will offer promotional discounts, speed upgrades, or package changes to keep you as a customer ('El ejecutivo te ofrecerá promociones para que cambies de opinión'). Decline firmly and repeat your cancellation request. You are not obligated to accept any offer.

Receive and save your folio number

Once the representative processes your request, they will give you a cancellation reference number (folio). Write this down — you will need it to complete the process at a service center. The call typically takes 20–25 minutes.

Gather required documents and equipment

Before visiting a service center, prepare: your valid official government-issued ID (INE, passport, or cédula profesional), your most recent Telmex bill, the modem and any other Telmex-provided equipment (router, phone handset), and your folio number. Only the account holder (titular del contrato) can complete the cancellation.

Visit a Telmex Centro de Atención

Locate the nearest Telmex customer service center at telmex.com/web/portal/sucursales. Present your folio number, ID, last bill, and equipment to the agent. The agent will verify there are no outstanding balances and inspect the modem's condition. Sign the cancellation documentation.

Receive equipment return receipt and confirmation

The agent will give you a comprobante de entrega de equipo (equipment return receipt) and confirm your cancellation folio. Keep both documents. The cancellation is registered within 24 business hours. Verify completion by logging into mitelmex.telmex.com — your service should no longer appear as active.
