Uruguay
eSIM.Fast 5G data plans. Instant activation, no SIM swap.

The best Uruguay eSIM gives you a fast connection without the resort-season markup. Flysimio runs on Claro, one of Uruguay's three operators alongside state-owned Antel and Movistar, covering Montevideo, the Atlantic coast and the main highway network. Uruguay punches well above its size on infrastructure — Antel was one of the earliest 5G movers in Latin America, and there is 5G in Montevideo, Maldonado and Punta del Este — so a cheap plan here does not mean a slow one. Plans are prepaid with no contract and no roaming surprises, your QR code arrives by email within seconds, every plan includes free mobile hotspot, and there's a 7-day money-back guarantee.

Getting online in Uruguay takes about two minutes. Confirm your phone supports eSIM — iPhone XS (2018) and newer and most Android flagships from 2020 qualify. Choose your Uruguay plan on Flysimio and pay with card, Apple Pay, or Google Pay; your QR code arrives by email within seconds. On Wi-Fi before you travel, open Settings → Cellular → Add eSIM (iPhone) or Network & Internet → SIMs → Add eSIM (Android) and scan it. When you land at Carrasco, switch the Flysimio line on and turn on Data Roaming for that line only. If you're arriving by ferry from Buenos Aires instead, switch it on as you dock at Colonia or Montevideo — an Argentine plan will not carry across the river.

Uruguay is compact and Wi-Fi is widespread, so most travellers need very little. For maps, messaging and email, roughly 300 MB a day is plenty — a 3 GB plan covers a week between Montevideo, Colonia and Punta del Este. Add photos and social media and 5 GB comfortably covers a fortnight. One seasonal caveat worth knowing: in January, Punta del Este and José Ignacio are among the busiest beach destinations in South America and the network is heavily loaded, so real-world speeds can lag what the signal bars suggest. That is congestion, not coverage, and no plan size fixes it. Use the calculator above to size your plan and top up if you run low.

Flysimio runs as a second line beside your usual SIM, so you keep your home number for calls and texts while your Uruguayan data flows over the eSIM — standard dual-SIM behaviour on iPhone XS and later and most Android phones from 2018. After installing, set the Flysimio eSIM as your cellular-data line and turn on Data Roaming for that line only; it simply lets the eSIM connect to Uruguayan networks, with no roaming fees. Keep your home SIM on for messages and calls, or switch it off to avoid your own carrier's charges. If you're unsure about your model, the compatibility page confirms it before you buy.

Every Flysimio Uruguay plan includes mobile hotspot at no extra cost and without throttling, so you can tether a laptop or tablet or share with a travel companion. As a data-only eSIM it has no Uruguayan phone number, but that rarely matters: WhatsApp is the default for messaging across Uruguay, and FaceTime and Google Meet handle calls over data. Your home number stays reachable on your primary SIM. Uruguay is one of Latin America's most card-friendly economies, so a working data connection covers most of what you'd otherwise need a local number for.

For a long weekend in Montevideo or a day trip across from Buenos Aires to Colonia, the 1 GB / 7-day plan is the economical choice. For a summer stay on the coast — Uruguayan summer runs December to February — or a longer remote-working stint in Montevideo, a 5 GB or 10 GB plan gives you room to video-call and upload without watching a meter. Because Flysimio gives you six months to activate, you can buy before you leave and validity only starts when your eSIM first connects in Uruguay. No contract, nothing to cancel.
