> Lei 10.703/2003 binds Brazilian carriers and shops, not a roaming Brazil eSIM. Maneiro runs on TIM at 5G, data-only, APN internet. Checked 17 August 2026.

## Does this apply to you? (a seven-article law, and it isn’t about your eSIM)

No — Lei nº 10.703/2003 binds Brazilian carriers and the shops that sell prepaid handsets, not a roaming eSIM installed before you land. A Maneiro eSIM isn’t the transaction either clause describes, so its fines — one flat R$100,000, one on a 24-hour clock — never reach a traveller.

A Brazil eSIM is a digital SIM profile installed on a phone before departure, connecting to a Brazilian mobile network on arrival without a physical card or a carrier-counter visit. Brazil has a federal law written for exactly one purpose: registering prepaid mobile users. Lei nº 10.703, de 18 de julho de 2003, runs seven articles and 3,926 characters. That’s short enough to read in one sitting, and we read it in full on 17 August 2026. It binds telecom operators “em operação no território nacional” — operating within national territory. It also binds the physical stores that sell prepaid handsets inside Brazil. A roaming eSIM for Brazil, installed on your phone before you land, isn’t the transaction either clause describes.

That’s a narrower claim than “Brazil has no rules.” The rules are real. One carries a flat R$100,000 fine — the only penalty in the law written without an “up to.” Another runs on a 24-hour clock, rarer than almost anything else in this category. Both land on a Brazilian carrier or a Brazilian shop, in the statute’s own words.

## What Lei nº 10.703/2003 actually requires

Article 1’s caput puts the core duty on the carrier:

> “Incumbe aos prestadores de serviços de telecomunicações na modalidade pré-paga, em operação no território nacional, manter cadastro atualizado de usuários.”

In English: prepaid telecom providers operating within national territory must keep an updated registry of users. The registry needs a name and a full address. Beyond that, one more item depends on who’s buying.

For an individual, §1 item I gives a choice, not a checklist:

> “I — no caso de pessoa física, o número do documento de identidade ou o número de registro no cadastro do Ministério da Fazenda;”

In English: for an individual, the identity document number or the registration number in the Ministério da Fazenda’s register — Brazil’s Cadastro de Pessoas Físicas (CPF). “Ou” means “or.” The statute asks a Brazilian carrier to record one of the two, not both. A page telling you Brazil demands “passport and CPF” together is reading a rule this law doesn’t write. For a company, item II asks for the Ministério da Fazenda registration number alone — Brazil’s CNPJ.

Two more duties run on an ongoing basis, not a one-time 2003 window. Under §3, a carrier has to hand registry data to a judicial authority immediately on request, absent a justified reason. The fine for withholding it runs up to R$10,000 per infraction. Under Article 3, a carrier has to make a listing of cell-phone thefts and robberies available to a judge, a prosecutor, or the police, on request. That listing needs a subscriber name, a serial number, and a phone code.

§2’s summons for carriers' *existing* 2003 subscribers is different. It gave them 90 days from promulgation to supply missing data. The Executive could extend that by an equal period. Planalto’s text carries a pointer here, “Vide Decreto nº 4.860, de 18.10.2003”, which we have not read. §2 was a one-time transition rule. It doesn’t recur for a new user, then or now.

## The store’s 24-hour clock, and the fine that comes with missing it

Article 2 puts a second party on the hook, and its deadline is worth quoting whole:

> “Os estabelecimentos que comercializam aparelhos de telefonia celular, na modalidade pré-paga, ficam obrigados a informar aos prestadores de serviços, no prazo de vinte e quatro horas após executada a venda, os dados referidos no art. 1º, sob pena de multa de até R$ 500,00 (quinhentos reais) por infração.”

In English: stores selling prepaid mobile phones must inform providers of the buyer’s registration data. They have twenty-four hours from the sale to do it. Miss that window, and the fine runs up to R$500 per infraction.

A deadline measured in hours, not days or months, is unusual for a statute like this one. The obligation sits on the “estabelecimento” — the physical point of sale that hands over a handset. It doesn’t sit on the buyer. It doesn’t sit on a foreign operator selling a roaming profile from outside Brazil, either. Article 2 has a clerk behind a counter, watching a clock. It doesn’t describe an eSIM bought through an app before you ever set foot in the country.

## Two clauses vetoed before signing

The published text carries two markers reading “(VETADO)” in place of numbered items. One sits under Article 1 §1 — item III, the third and last entry in that paragraph’s list. Item I holds the rule for individuals, item II the rule for companies, and item III was cut. The other sits under Article 3 §2 — item I, the first of three penalties listed for a carrier that won’t hand over its theft-and-robbery listing.

Item II of that same penalty list survived: a fine of R$100,000. So did item III: contract rescission.

We don’t know what either vetoed clause said, and we’re not going to guess. Planalto’s own page for this law carries a “Mensagem de veto” link. It carries no “Revogad-” flag anywhere in the text. Nothing here reads as repealed — it was partly struck before signing, not struck later. President Luiz Inácio Lula da Silva signed the law on 18 July 2003. Part of this law was cut at the signing stage, and the seven articles that survived are the text Planalto still publishes today. We read the statute, not the enforcement record behind it.

## Article 4: what a registered subscriber owes — and why a traveller isn’t one

A registered subscriber owes the carrier prompt notice of theft, loss, or a device transfer, backed by a fine up to R$50 plus a signal block. None of it reaches a traveller: those duties attach only to a Brazilian carrier’s cadastro, which a roaming Maneiro eSIM never enters.

Article 4 puts duties on the user, not only the carrier and the store. A registered subscriber has to report certain events immediately, to the carrier or its accredited agents. That covers the theft, robbery, or loss of the device. It also covers a transfer of the device to a new owner, or any change to their registration information. Miss one, and the sole paragraph sets the penalty:

> “O usuário que deixar de atender ao disposto neste artigo ficará sujeito à multa de até R$ 50,00 (cinqüenta reais) por infração, cumulada com o bloqueio do sinal telefônico.”

In English: break one of these duties and the fine runs up to R$50 per infraction. “Cumulada” is the word that matters. The signal block comes with the fine, not instead of it. The block is the part that bites; the fine alone is small money.

Every duty in Article 4 attaches to holding a place in a Brazilian carrier’s cadastro under Article 1. A foreign roaming profile was never entered into that registry. A Maneiro eSIM installed before departure isn’t a line in a Brazilian carrier’s registry. It’s a contract with the operator that issued it, roaming onto TIM’s network once you land. Nothing in Article 4 has anywhere to attach.

## What we haven’t read: ANATEL’s activation rules

We have not read ANATEL’s own activation regulations — Resolução 477/2007 or Resolução 632/2014 — and neither is cited on this page. Lei 10.703 names ANATEL as the body that enforces its fines, but the counter-level mechanics of activating a physical prepaid SIM live in those separate rules, not here.

This law names ANATEL — the Agência Nacional de Telecomunicações — as the body that imposes its fines administratively, under Article 5. Article 6 has ANATEL running an information campaign about the 2003 transition summons, jointly with carriers. What this law doesn’t do is spell out the counter-level mechanics of activating a prepaid line. That detail lives in ANATEL’s own regulations, not in Lei 10.703/2003. Two are commonly cited for this: Resolução 477/2007, and the Regulamento Geral de Direitos do Consumidor, Resolução 632/2014. We have not read either one for this page, and neither is cited here. If you’re looking for the exact activation procedure a Brazilian shop follows for a physical SIM, that’s where it lives — not in the seven articles above.

## What you get: Maneiro on TIM, 5G, data-only

Maneiro is the eSIM for Brazil this site sells, roaming on the TIM network at 5G, data-only (Airalo catalog data, checked 7 September 2026). Checkout carries no Know Your Customer (KYC) step.

| Data | Duration | Price |
|---|---|---|
| Unlimited data, duration | Price |
|---|---|

Airalo lists its own rate separately on its site.

The 5 GB, 30-day plan is the workhorse most trips of a few weeks land on.

## The APN you type in by hand: internet

Access Point Name (APN) is the setting a phone uses to reach a carrier’s mobile data network. **On Android, enter ****`internet`**** into the APN field manually — without it, Maneiro installs but carries no data.**

iOS fills the APN automatically once the profile installs. Android doesn’t (Airalo catalog data, checked 7 September 2026).

The setting sits under Settings > Network & internet > SIMs > Maneiro > Access Point Names on stock Android. The exact path shifts slightly by phone maker. Add a new APN. Set the APN field to `internet`. Leave the rest at their defaults, save, then select it as the active APN for the Maneiro line.

Android’s manual-APN requirement isn’t unique to Brazil — 73 of the catalog’s 215 countries need it typed in by hand, 121 of 368 operator entries (32.9%, [airalo.com/brazil-esim](https://www.airalo.com/brazil-esim), checked 3 September 2026). Worth ruling out first if a freshly installed profile shows no data. Do this once, on Wi-Fi, before you rely on it.

## Before you fly, and on landing

**Install the profile before departure, on Wi-Fi — not at the gate, and not after you’ve already landed.** The QR code or install link needs a working internet connection to complete. Arrival connectivity at a Brazilian airport isn’t guaranteed.

Nothing activates at install. Maneiro starts its own clock once your phone actually connects to TIM. That’s not the moment you install the profile, and not checkout either. A profile that shows installed but inactive before boarding is normal, not a fault.

On landing, switch on data roaming for the Maneiro line specifically. Confirm the APN field reads `internet` if you haven’t set it already. Running Maneiro alongside a home SIM works on any dual-SIM phone. Set Maneiro as the data line. Turn off cellular data — not the whole line — on the home SIM, so nothing pulls an expensive home-carrier roaming charge by accident.

Maneiro is data-only: no Brazilian phone number, no SMS, no calling minutes. Anything that verifies you by SMS to a Brazilian number sits outside what this profile does — a delivery app, a local bank’s one-time code, a ride-share sign-up. That’s a product fact about a data-only line, not a consequence of Lei 10.703/2003. The law’s registry duties never had a roaming profile like this one to attach to in the first place.

## FAQ

## Sources and freshness

Checked against Lei nº 10.703, de 18 de julho de 2003 (“Dispõe sobre o cadastramento de usuários de telefones celulares pré-pagos e dá outras providências”). We read it in full — all seven articles, 3,926 characters — from planalto.gov.br/ccivil\_03/leis/2003/l10.703.htm on 17 August 2026. The page carries no “Revogad-” marker and no “Texto compilado” notice. Article 7 states the law entered into force on its date of publication (D.O.U., 21 July 2003).

We also downloaded Lei nº 9.472/1997, Brazil’s general telecommunications law (130,394 characters), for context. We did not search it by name for a separate identification requirement, and it isn’t cited on this page.

We have not read ANATEL’s Resolução 477/2007 or Resolução 632/2014, which govern the mechanics of activating a prepaid line. We also have not read Decreto nº 4.860 of 18 October 2003. Planalto’s text points to it beside Article 1 §2. No claim on this page rests on any of the three. Plans, pricing, network, generation, and the no-KYC checkout come from Airalo’s own Maneiro catalog data for Brazil, checked 7 September 2026. Airalo can change any of it without notice. This page has not tested what happens if a Brazilian retail store misses its 24-hour window in practice, and makes no claim about enforcement rates.

## FAQ

Do I need to show ID to buy an eSIM for Brazil?
No, not for Maneiro. Airalo's checkout for this product runs no KYC step and asks for no ID upload (Airalo catalog data, checked 17 August 2026). Brazil's registration law is real, and it does put an identity duty on someone. That duty falls on a Brazilian carrier signing up a local prepaid line, and on the store that sells the handset — not on a roaming profile bought before you fly.

Does Brazil's SIM registration law apply to a roaming eSIM?
No. Lei 10.703/2003, Article 1, binds carriers "em operação no território nacional" — prepaid providers operating inside Brazil. Article 2 binds "estabelecimentos" selling handsets inside the country. A foreign roaming profile is neither a local carrier's own line nor a handset sold at a Brazilian counter.

Can I get an eSIM for tourists in Brazil?
Yes. Maneiro is a data-only eSIM built for exactly this: install it before your trip, and it roams onto TIM once you land, with no local registration step at checkout (Airalo catalog data, checked 17 August 2026).

Is my phone compatible with Brazil eSIMs?
Only if the phone itself supports eSIM and is carrier-unlocked. That's a device question, not a Brazil-specific one — check your phone model's settings for an eSIM option, or its factory specs, before you buy.

What's the best eSIM for Brazil?
This page covers one product: Maneiro, roaming on TIM at 5G, data-only. The Lei 10.703/2003 scope explained above holds the same way regardless of which data-only Brazil eSIM you pick — it binds local carriers and stores, not a foreign roaming profile.

Does a travel eSIM have a phone number?
Not this one. Maneiro is data-only: no Brazilian number, no SMS, no voice minutes (Airalo catalog data, checked 17 August 2026). That's also why Article 4's duties have nothing to attach to here. Reporting a stolen or transferred device only matters for a subscriber's cadastro entry, and a data-only roaming profile was never entered into one.

What happens if a Brazilian store misses the 24-hour reporting window?
Article 2 sets a fine of up to R$500 per infraction for a store that doesn't pass a buyer's registration data to the carrier within 24 hours of the sale. That duty and that fine sit on Brazilian retail stores selling prepaid handsets inside the country — not on a foreign eSIM issuer selling a roaming profile from outside it.

What's the APN for Maneiro on Android?
`internet`, entered manually under your phone's Access Point Names settings. iOS sets this automatically; Android doesn't. Brazil sits in the 73-country slice of Airalo's catalog where Android needs this typed in by hand — 121 of 368 operator entries, 32.9%, checked 3 September 2026.
