El Salvadorchecked Aug 2026StraightforwardStaying connected in El Salvador.
El Salvador is small, increasingly visited, and reasonably well covered where visitors go. Local data is cheap and the gaps are short, which makes this a short page.

A local SIM, and it is cheap
Signal gaps
The northern mountains
Coverage is good in San Salvador, along the Pacific coast from La Libertad to El Tunco and El Zonte, and on the main highways including the route to Santa Ana and Suchitoto. It thins in the northern mountains toward the Honduran border, in the Morazan interior and on some volcano approaches. A local Tigo or Claro prepaid SIM with a data bundle is cheap, bought with your passport, and it is the cheaper option; a Nomad eSIM at a few dollars per gigabyte works from landing. Your US carrier charges about 10 to 12 dollars a day to roam (AT&T and Verizon day passes), though AT&T caps its Day Pass at 10 daily fees per line per bill period, about 120 dollars, while Verizon has no equivalent cap and keeps billing daily. T-Mobile's mid and upper tiers include 5GB to 30GB of high-speed data abroad before slowing to 256kbps. El Salvador is on AT&T's covered-destination list, so a day pass applies rather than pay-per-use. The country uses the US dollar, which removes a layer of friction from topping up. Never roam pay-per-use, at about 2 dollars a megabyte.
Cheap, and the local SIM wins on price
A Tigo or Claro prepaid SIM with a data bundle is inexpensive, sold in carrier shops, malls and at the airport with your passport, and both networks cover the capital, the coast and the main highways comfortably, so there is no network worth paying extra for. One quiet advantage: El Salvador uses the US dollar, so topping up does not involve a currency conversion or an unfamiliar payment app.
That makes the local SIM the cheaper answer, and we earn nothing on it. A Nomad eSIM at a few dollars per gigabyte is the convenience option: no shop, working from landing, useful if you are arriving late at Comalapa and want a ride sorted before you leave the terminal.
Where it thins, briefly
The gaps here are real but brief, because the country is small: the northern mountains toward the Honduran border, the Morazan interior, the higher approaches on Santa Ana and Izalco, and some of the back roads inland from the coast. You are rarely more than an hour from coverage, which is a different situation from Patagonia or Namibia.
So the usual habit is enough: download offline maps for a volcano hike or a drive into the hills, and save your accommodation's number. Surf towns along the coast have workable coverage and widespread cafe wifi. This guide is written for US travelers departing the US.

What roaming costs, and the covered-list check
Worth confirming because it changes the advice completely: El Salvador is on AT&T's covered-destination list, so a day pass applies at about 10 to 12 dollars a day rather than the pay-per-use rate you would face in an uncovered country. AT&T caps land fees at 10 daily fees per line per bill period, about 120 dollars, and Verizon has no equivalent cap.
T-Mobile's current tiers include roughly 5GB on Experience More, Magenta MAX and Go5G Plus, 15GB on Experience Beyond and Go5G Next and 30GB on Better Value, slowing to 256kbps after, so check your own plan first: on a week of surfing with cafe wifi that may be all you need. Do not roam with no plan, at about 2 dollars a megabyte.
Common questions
Quick answers.
How much is a SIM card in El Salvador?
A Tigo or Claro prepaid bundle is cheap, bought with your passport in a carrier shop, a mall or at the airport. Since El Salvador uses the US dollar, topping up involves no currency conversion, which removes the usual friction.
Is El Salvador covered by US carrier day passes?
Yes. El Salvador is on AT&T's covered-destination list, so a day pass applies at about $10 to $12 a day rather than the pay-per-use rate that would apply in an uncovered country. That is worth confirming, because the advice would be completely different otherwise.
Will I have signal on the Salvadoran coast?
Yes, generally good along the Pacific coast from La Libertad through El Tunco and El Zonte, with widespread cafe wifi in the surf towns. It thins in the northern mountains, the Morazan interior and on the higher volcano approaches.
How much does it cost to use my US phone in El Salvador?
About 10 to 12 dollars a day on an AT&T or Verizon day pass, so roughly 70 to 84 dollars a week. AT&T caps its Day Pass at 10 daily fees per line per bill period, so about 120 dollars covers the rest of that bill period on land, while Verizon's TravelPass has no equivalent cap and keeps billing daily. T-Mobile is worth checking first, since its mid and upper tiers include 5GB to 30GB of high-speed data abroad before slowing to 256kbps.
More on El Salvador
The little money things nobody warns you about.
- Do you need a visa or a tourist card for El Salvador?The short answer is no to both, and the second half of that is recent enough that most of the internet, including some official pages, still says otherwise.
- Cash or card in El Salvador?Most of our cash-or-card guides are about avoiding a bad exchange rate. This one cannot be, because there is no exchange rate. What replaces it is a simpler question about where you can tap and what you can break.
- Tipping in El Salvador, and how not to do it twiceMost tipping guides worry you are about to under-tip. In El Salvador the more likely error runs the other way, because the tip is often already on the bill and easy to miss.
- Taxis and ride-hailing in El SalvadorGetting around San Salvador is one of the places where an app is not just cheaper but genuinely simpler, because the alternative involves negotiating every fare from scratch.
- What does getting sick in El Salvador cost?El Salvador has a specific and slightly unusual shape: the doctors in the main private hospitals are frequently well trained, often in the US, while the emergency and ambulance layer around them is thin. That gap is what to plan around.

Our own readChecked Aug 2026. El Salvador's inclusion on AT&T's covered-destination list was verified against AT&T's own list, because it was one of two countries in this wave we would not state a day-pass price for without checking: in an uncovered country the honest line is a pay-per-use warning instead. The local SIM is cheaper than the eSIM we earn on and the page says so. Coverage reads are the desk's from operator footprints and traveler accounts, and the country's size means the gaps are short.
