Near the Terminal 3 gates, Samsung is the spot for last‑minute tech
Right in Terminal 3 airside at GRU, this Samsung store works well if you realize at the gate that your charger, cable, or headset is dying. It mainly carries phones, tablets, headphones, watches, and accessories, so think more "upgrade or replace" than full repair shop. Expect airport pricing: accessories often run higher than in São Paulo city stores, but you pay for not having to leave security in Terminal 3.
The shop keeps hours that roughly match long‑haul banks in Terminal 3, usually open from early morning into the late evening while the Europe and US flights move. Stock leans toward recent Galaxy phones and buds, with some power banks and USB‑C chargers that actually fast‑charge. If you need a basic cable under R$100, you’ll probably find one here, but branded extras and wearables climb quickly in price.
Product lineup in Terminal 3 typically includes display models you can test, which helps if you’re choosing between different Galaxy Buds or watch sizes before a 10‑ to 12‑hour flight. Staff usually speak at least some English and Spanish in addition to Portuguese, useful if you’re connecting between Star Alliance or SkyTeam long‑hauls. Don’t expect deep technical troubleshooting beyond simple setup or pairing.
One practical move: check your existing cables and adapters at your gate in Terminal 3 before walking over, then buy only the one thing that will actually save your flight (usually a USB‑C charger or headset with noise isolation) rather than browsing the full Samsung lineup on impulse.
