Best eSIM for Guyana 2026: 11 Providers Compared

Nearly all of Guyana's mobile coverage hugs the Atlantic coast around Georgetown, so an eSIM keeps you online in the capital and coastal towns while Kaieteur Falls and the Rupununi remain offline. Guyana is South America's English-speaking outlier, a country of colonial Georgetown, the thundering Kaieteur Falls and vast rainforest and savannah interior. Staying connected concentrates in the coastal capital, with long offline stretches inland, and an eSIM is the cleanest way to get online without a local SIM. Install before you fly, land at Georgetown's Cheddi Jagan International, and your phone connects when it finds a local network.

ONE Communications and Digicel: Guyana's two networks

Guyana has two mobile operators. The larger one is still called GTT by many Guyanese, but it rebranded as ONE Communications in September 2024, as Stabroek News reported at the time. Digicel is the other network. Both run 4G along the coast, where most of the population lives, and both sell prepaid SIMs in Georgetown.

A local SIM gives you a Guyanese number, which helps when lodges and drivers coordinate by phone. Buying one means a shop visit with your passport after landing at Cheddi Jagan International. The travel eSIM in the tables below is installed at home and connects to a local network when you land, and the networks it uses are listed in its plan details.

Georgetown and the coast road from Parika to Corriverton

Coverage is good in Georgetown and along the coastal belt: east to New Amsterdam and Corriverton on the Berbice side, and west across the Demerara to Parika, the jumping-off point for boats up the Essequibo. Maps, messaging and video calls work along this strip, which is where most business travelers spend their time.

Guyana's oil boom has brought a steady flow of business visitors to Georgetown, and hotel and office Wi-Fi is common there. Mobile data mostly covers the gaps: the drive from the airport at Timehri, meetings across town and evenings out.

Guyana eSIM plans and prices, side by side

Guyana is a market where a travel eSIM saves the hassle of a local purchase. Simsima runs on the local networks. Here is how a light 1 GB pack compares across eSIM providers:

If you would rather not track your usage, Guyana also has unlimited-data eSIMs, with speed reduced after a daily high-speed allowance until the next day. Here is how the unlimited plans compare:

Simsima's full Guyana lineup runs from small packs up to larger monthly allowances on the local networks. Because coverage concentrates on the coast and the interior is offline, a modest 2 to 3 GB plan is enough for many travelers, with more for longer coastal stays.

Kaieteur, Iwokrama and the Rupununi: planning for no signal

The interior is a different world. Kaieteur Falls, which drops 226 meters according to the Guyana Tourism Authority, is reached by small plane from Ogle, and you should not count on a signal at the falls. The rainforest lodges at Iwokrama, Atta and Rewa, and the savannah ranches of the Rupununi such as Karanambu, are largely beyond mobile coverage, with lodge Wi-Fi where it exists.

Coverage has been extending along the road south to Lethem, but stretches of it remain offline. Before you fly or drive inland, download offline maps, save your lodge's contact details and send your itinerary to someone at home.

How much data a Guyana trip uses

A week split between Georgetown and two nights at an interior lodge uses little mobile data, since half the trip is offline: 2 to 3 GB covers maps, messaging and photo uploads on the coast. A two-week business stay in Georgetown with video calls away from the hotel Wi-Fi needs 5 to 10 GB, or an unlimited plan.

How to install your Guyana eSIM before Cheddi Jagan International

Installation takes a couple of minutes and is best done at home on Wi-Fi before you fly, which avoids arranging a local SIM. The plan activates on its own when it connects to a local network on arrival.

1. Buy your Guyana plan on Simsima and open the confirmation with your QR code
2. On your phone, go to Settings, then Mobile or Cellular Data, and choose Add eSIM
3. Scan the QR code or use the one-tap install link, then label the plan Guyana
4. Keep your home line as default for calls and texts, and set the eSIM for data
5. Turn on data roaming for the eSIM line only, then land in Georgetown and go online

Crossing to Brazil at Lethem or to Suriname at Moleson Creek

Two land borders see regular traffic. In the south, a bridge over the Takutu River links Lethem with Bonfim in Brazil, the route to Boa Vista. In the east, the ferry from Moleson Creek near Corriverton crosses the Corentyne River to South Drain in Suriname. A Guyana plan stops working once you cross; add a plan for Brazil or Suriname, or pick a multi-country plan that lists every country on your route.
