Best eSIM for Paraguay 2026

Tigo vs Claro vs Personal — and a 5G race that's still running

Tigo, run by Luxembourg-based Millicom, has been Paraguay's largest operator for years and has the deepest reach into smaller towns and rural departments — the name you'll see on your phone most often outside Asunción. Claro and Personal (part of Telecom Argentina's Núcleo group) both compete hard in the cities, with Claro traditionally the stronger of the two in major population centers.

What's genuinely new this year is the 5G rollout, and it's been a bumpier process than in most countries this series has covered. Claro and a smaller player, Nubicom, won Paraguay's first 5G spectrum auction in mid-2025 and Claro switched on the country's first commercial 5G network in early 2026, reportedly ahead of its own 180-day deadline. Tigo and Personal sat that first auction out — reportedly over tender conditions on equipment-supplier origin that affected vendors like Huawei — then came back for a second auction in 2026 and won it as the only two bidders: Tigo took the 2.3GHz band, Personal the 3.7GHz band. Both now face the same 180-day countdown Claro had, putting their own 5G launches due by roughly February 2027, and Paraguay's regulator has reportedly granted shorter 5G licence terms than any other country in Latin America.

None of this is a decision a visitor needs to make — a roaming eSIM, Siima's included, connects to whichever partner network has the strongest signal where you are, automatically. It's worth knowing the 5G story mainly because by the time this guide gets revisited, the current head start Claro has on paper may well have narrowed or flipped.

The Paraguay-only plan wins here — and Siima's regional plan skips Paraguay entirely

Several of the most recent guides in this series — Monaco, Gibraltar, Senegal, Madagascar — were places where a worldwide eSIM plan actually beat the local-only one. Paraguay is back to the more usual pattern: checked against Siima's live catalogue, the Paraguay-only plan is cheaper than the worldwide plan at every size sold, by a wide and growing margin.

The one case for paying more is a multi-country South America trip. Siima's own LATAM regional plan explicitly doesn't cover Paraguay — only Mexico, Brazil, Argentina, Chile, Colombia, Peru, Ecuador, Uruguay, Costa Rica, El Salvador and French Guiana are included — so a Paraguay leg on a regional-plan trip needs either the worldwide plan or a second, Paraguay-only one stacked alongside it. For a Paraguay-only trip, there's no contest: buy local.

Ciudad del Este, Itaipu and the tri-border crossing

Ciudad del Este is Paraguay's second city and one of South America's busiest commercial hubs, built almost entirely around cross-border shopping — it sits directly across the Paraná River from Foz do Iguaçu, Brazil, connected by the Friendship Bridge, with Puerto Iguazú, Argentina a short drive further on. This is the point where three countries meet closer than almost anywhere else on the continent, and it means a phone can genuinely pick up a Brazilian or Argentine tower instead of a Paraguayan one while you're still standing on Paraguayan soil — worth knowing if your eSIM is Paraguay-only rather than regional or worldwide.

The main draw out here is Itaipu, the hydroelectric dam Paraguay co-owns and co-operates with Brazil — for years the single highest-output dam on Earth by annual generation, a title it has traded back and forth with China's Three Gorges depending on the year's rainfall on each river. The dam structure itself straddles the Paraguay-Brazil border, and the visitor center and tours sit on the Paraguayan side.

One honest caveat: the US State Department rates Paraguay overall at Level 1, "Exercise Normal Precautions," as of its August 2026 update — but five northern and border departments, including Alto Paraná, where Ciudad del Este sits, carry a Level 2 advisory for smuggling-related crime along the Brazil border. Millions of day-trippers visit Ciudad del Este and Itaipu every year without incident; the caveat is about the wider department along quieter stretches of the border, not the dam tour or the shopping district itself.

Coverage by destination

How much data do you need in Paraguay?

Most visitors split their time between Asunción and a day or two around Ciudad del Este/Itaipu, which keeps data needs modest outside the Chaco.

Paraguay is also one of the few countries where an indigenous language shares official status with Spanish on equal footing — most Paraguayans speak Guaraní at home alongside Spanish, and road signs, radio and casual conversation mix both freely, which is part of what makes the country feel distinct from its larger neighbors rather than an extension of either.
