Claro Brazil currently advertises Claro Sync with no additional monthly fee for eligible postpaid customers. The service lets a compatible LTE smartwatch share the phone line’s number and plan, but it still requires an eligible Claro plan, a supported phone-and-watch combination, and carrier activation. It is not a free standalone watch plan—and Claro’s pricing differs by country.
What Claro Sync does—and what changed
Claro Sync connects a compatible cellular smartwatch to a customer’s existing Claro mobile line. Once activated, the watch can use mobile data and make or receive calls away from the phone’s Bluetooth range, subject to Claro coverage. It shares the phone’s number and plan; it does not create a separate number or a separate data allowance. Claro Brazil describes the service and its shared-plan operation.
Claro’s current Brazilian pages say Claro Sync has “sem custo adicional” (no additional cost). That is a change from the separately billed add-on reflected in historical Claro Brazil terms. Brazilian technology coverage reported the fee change in December 2024, but Claro’s current public information does not clearly state the exact effective date or explain how every existing billing arrangement was handled. The timing was reported by TudoCelular; the current price position is supported by Claro’s FAQ.

“No additional fee” refers to the Claro Sync add-on. You still need the underlying mobile plan and a compatible cellular watch. It does not cover the watch purchase, add data or voice allowances, pay for repairs, or guarantee roaming. Claro says its Brazilian Claro Sync service is not compatible with international roaming.

Who can use it?
Claro’s Brazilian information describes Claro Sync for eligible Claro Pós-pago individual customers. Do not assume that every Claro customer qualifies: the current material does not establish eligibility for all prepaid, Controle, or postpaid plans. Confirm your specific plan with Claro before buying a watch or relying on the service.
- Your mobile line is with Claro Brazil and your plan is eligible.
- Your watch is a cellular/LTE model with eSIM support—not a GPS-only version.
- Your phone, watch, and the exact model variant are supported by Claro in Brazil.
- Claro has coverage where you intend to use the watch.
- You understand that the watch shares your phone plan and that international roaming is not supported for Claro Sync in Brazil.
Compatibility is model-specific, and retail names can hide important differences. Claro’s Apple Watch guidance lists cellular versions from several generations, including Series 3 through Series 11, SE and SE 2022, SE 3, Ultra and Ultra 2. For Samsung, Claro lists LTE versions of Galaxy Watch, Active2, Watch 3, Watch 4/4 Classic, Watch 5/5 Pro, Watch 6/6 Classic, Watch 7, and Watch Ultra in its Samsung activation guidance. Check Claro’s current list and the watch’s precise model identifier before purchase; a brand name alone is not proof of compatibility.
Claro’s Brazil service page links to Huawei activation guidance, but that does not mean every Huawei LTE/eSIM watch is supported. Verify the exact Brazilian model with Claro before buying, particularly for imported watches. Business customers are a separate case: Claro’s business page describes its own offering and mentions up to four Apple Watches on a business line. Do not treat that business detail as a personal-plan rule.

How to activate Claro Sync
Apple Watch
Use an iPhone and an Apple Watch GPS + Cellular model. Claro’s documented route is:
- Open the Watch app on the iPhone.
- Tap Celular, then Configurar celular.
- Tap Configurar celular again and wait for the Claro login page.
- Enter the requested Claro credentials, review and accept the terms, then select Claro Sync and continue.
- Wait for the activation confirmation SMS.
Menu wording can vary with software and language. If you are moving the watch to a new iPhone, Claro says it may need to be unpaired from the old phone and paired with the new one before cellular service works properly. Do not assume an iPhone backup transfers the carrier profile automatically. See Claro’s Apple Watch instructions.
Samsung Galaxy Watch
Samsung setup follows a different eSIM process. Claro’s documented route uses activation information or an eSIM QR code obtained through Claro:

Claro’s current pages establish the present no-additional-cost position, but they do not clearly promise automatic migration, a refund for past charges, or a credit on a particular billing cycle. Nor do they explain whether every legacy or corporate arrangement follows the same rules.
- Check your next bill for a separate Claro Sync charge and compare it with earlier invoices.
- If it remains, contact Claro on 1052 and ask which service or billing code the charge represents and whether it applies to your plan.
- Request a billing explanation and keep the service protocol number. Ask directly whether a correction or credit is due; do not assume one will be automatic.
- If the watch is working, do not cancel it solely to test the price change before confirming how reactivation would work.
A continuing charge could reflect an older billing setup, another watch or service, a different plan or customer segment, or a service record that remains active after device-side removal. Ask Claro to identify the specific line item rather than assuming its cause.

How to cancel
Removing a watch’s eSIM or mobile plan from its settings may not, by itself, close the carrier-side service record. Follow the relevant cancellation steps and obtain confirmation from Claro if you need the service fully cancelled.
Apple Watch
Open the Watch app, tap Celular, select Claro Brasil, and sign in if prompted. Tap Cancelar, then Fechar. Claro’s cancellation instructions describe this route.

Why the watch may not connect
- No cellular option or service: Confirm the watch is the LTE/cellular version, not GPS-only, and that its exact model is on Claro’s Brazil compatibility list.
- Activation does not complete: Check that the Claro line and plan are eligible, the correct eSIM process was used, and you received the carrier’s activation confirmation. For Samsung, confirm you have the correct Claro QR code or activation information.
- Calls fail but other features work: Check coverage and the watch’s mobile-network settings; voice calling may also depend on VoLTE support for the device and network.
- You changed phones: For Apple Watch, unpairing from the old iPhone and pairing with the new one may be necessary. Recheck the carrier plan in the Watch app.
- You removed the plan but still see a charge: Contact Claro to check whether the carrier-side service was cancelled; deleting a profile on the watch is not reliable proof that billing records were closed.
- You are outside Brazil: Claro Brazil says Claro Sync is not compatible with international roaming. A cellular watch should not be treated as a travel eSIM.
Brazil is not every Claro market
Claro Sync terms vary by country. Claro Brazil currently advertises no additional monthly charge for eligible customers, while Claro Colombia lists COP $15,000 per smartwatch per month, with an introductory promotion in some cases. Check the local Claro site for the country where your line is billed; the Brazilian policy is not a regional or worldwide promise.
Is cellular Claro Sync worthwhile?
The fee change makes the connectivity add-on more attractive if you already have an eligible Claro postpaid plan and a compatible LTE watch, especially if you regularly run, exercise, commute, or do errands without your phone. It adds less value if you nearly always carry your phone, own a GPS-only watch, rely on international roaming, or expect a separate watch number or data bucket. A Bluetooth/Wi-Fi watch may be enough for someone who stays near their phone.
Before buying a watch specifically for this feature, confirm plan eligibility and the exact Brazilian model with Claro. “Free Claro Sync” removes the advertised monthly add-on fee; it does not remove the need for a mobile plan, compatible hardware, eSIM provisioning, or Claro coverage.
