Guarulhos Airport SIM cards: what to expect at the counter

Why GRU is different from most airports we cover

The usual verdict on airport SIM counters is that they exist to charge you a premium for being tired. Guarulhos is one of the exceptions. Tourist data packages run R$30–80, which our source converts to roughly $6–16 — genuinely cheap by global standards, and cheap enough that the counter competes with buying online instead of merely existing beside it.

South America's busiest international airport also has more than one operator on site. TIM runs kiosks in the international terminal arrivals hall. Vivo and Claro have a presence too. Staff at the counters typically speak basic English, and the queue runs ten to twelve minutes.

We do not hold opening hours for any of them, and we do not hold which of GRU's terminals each sits in beyond "international arrivals". Treat both as things to establish on the day rather than plan around.

Registration, and what travellers report about it

What our data holds for Brazil is a single line: passport or ID required for registration. Take your passport to whichever counter you reach, and that is the requirement we can vouch for.

Brazilian travel writing describes something stricter — prepaid lines registered against the CPF, the national taxpayer number, which visitors do not have and cannot produce at a kiosk. In those accounts TIM's tourist packages are the ones built for international visitors, and Vivo and Claro are where the question comes up. We have not verified how any individual GRU kiosk handles it, and our own records say nothing about a CPF, so this is not a basis for sending you across the arrivals hall. If you are asked for a number you do not have, that is the reported experience rather than a sign something has gone wrong, and trying the next counter costs a few minutes.

The other way around it is to arrive already connected. A travel eSIM requires no Brazilian identification of any kind, because the registration happens with the seller before you ever land.

If you are only connecting, buy nothing

GRU is a major transfer point for the whole continent. If São Paulo is the middle of your journey rather than the end of it, a Brazilian SIM buys you nothing — the plan is country-specific and your connection is measured in hours. Use the terminal wifi and buy for the country you are actually going to, before you leave home.

The numbers

Prices are per plan in US dollars with the duration attached. Airalo's rows were read from its own store on 13 August 2026, Saily's from Saily's own site on 16 August and Nomad's from Nomad's on 18 August. The rest are indicative listings we have not confirmed.

This page used to say Brazil really did stop at 20 GB. The Nomad price we printed on that rung, $26, had never been read off its site. Both were wrong. Nomad's 20 GB is $31, and it sells a 50 GB month at $45 — $0.90 a gigabyte, and by a wide margin the cheapest data in the country. Airalo does stop at 20 GB, where its $36 is $1.80 a gigabyte and its 15-day version at $35 works out slightly better at $1.75. Saily's verified 20 GB is $39.99, or $2.00 a gigabyte.

Saily's monthly prices were understated on this page until now — its 10 GB month was recorded at $17.99 and is in fact $24.99 — which makes it the dearest metered seller in Brazil above 3 GB rather than one of the cheapest. Its verified 1 GB for seven days at $3.99 is the exception, and the only eSIM row that comes in under the bottom of the TIM pack range.

Now put the counter beside that. A R$30–80 airport pack, at the source's own $6–16 conversion, is in the same territory as the small eSIMs and undercuts them outright if the allowance is decent. This is a market where we would not tell you to skip the airport counter on price. The whole ladder is on the Brazil hub.

Getting into São Paulo

The EMTU Airport Bus Service runs frequently to Republic Square for R$4.80 — very cheap, but 60 to 90 minutes once São Paulo traffic has its say. A taxi to the centre is R$80–130, and a rideshare through Uber or 99 is usually cheaper, around $12–20. There is no direct metro connection; a Guarulhos–São Paulo metro service is under development.

Ordering a rideshare needs a connection at the moment you land, which is the practical argument for an eSIM over the kiosk regardless of price: it is live before you reach the door, while the kiosk is ten to twelve minutes you spend before you can call a car.

Which network you are actually on

No provider publishes a confirmed host network for Brazil. Airalo, Nomad, Saily and eSIMCard publish nothing at all — Maneiro is Airalo's product name for its Brazilian plans, not a carrier — and eSIM Go has no consumer page on which it could. eSIM Go sells wholesale to resellers and publishes no consumer price — checked on esim-go.com on 18 August 2026, where there is no basket, no checkout and no per-country page — so its rows cannot be bought or ever verified. See our eSIM Go page. Holafly names nothing either. This page used to give it TIM and Vivo, which came from our own data; Holafly publishes no host carrier for any country — we read its prices for 28 of them off esim.holafly.com on 18 August 2026 and not one names an operator. An earlier version of this page named Vivo and Claro for Nomad as well; that came from our own older text, not from Nomad.

Buy a pack at a kiosk and you know whose network you are on, because you picked the carrier at the counter. In a country this large, knowing is worth something.
