El Salvador is small, and its coverage is good along the routes visitors use — San Salvador, the surf towns of El Tunco and El Zonte, the Ruta de las Flores and Lake Coatepeque. Travel eSIM data there is expensive, though, and local SIMs are cheap. So the honest advice depends on how long you are staying.
Short answer: a small eSIM installed before you fly covers arrival and a short trip. For a surf month or remote work, buy a local SIM.
What an El Salvador eSIM costs
At the time of writing (October 2026), Wanderly's El Salvador plans start at $4.99 for 1GB (7 days), with 3GB for 15 days around $12 and 5GB for 30 days around $19 — roughly $3.80–$5 per GB. That is well above the $1.43 global median in the Wanderly eSIM Price Index, and the catalogue tops out at 5GB.
eSIM vs a local SIM
- Travel eSIM: online on landing, no store visit, home SIM stays in the phone. Best for the first days and short trips.
- Local SIM (Tigo, Claro, Movistar, Digicel): sold at the airport and in town with your passport; much cheaper per gigabyte. Best for longer stays and remote work.
Many surfers do both: a 1GB eSIM to arrange the airport transfer and reach the hostel, then a local SIM.
Coverage where you will actually be
- San Salvador: good 4G.
- El Tunco, El Zonte, El Sunzal (Surf City): good in town; patchy on some beaches.
- Ruta de las Flores (Juayúa, Ataco): good in the towns.
- Lake Coatepeque and Santa Ana volcano: coverage at the lake and trailhead; patchy on the climb.
- El Imposible National Park: limited.
