The best eSIM for El Salvador is a data plan sized to your days there, installed on Wi-Fi before you fly. A SimOptions El Salvador eSIM does that: it runs on 4G/LTE, activates when you arrive in El Salvador and comes in sizes from 1 GB for 3 days to 20 GB for 15 days. It has no Salvadoran phone number, so you call through WhatsApp or FaceTime. Need a local number? Local carriers such as Claro and Movistar offer eSIMs too, through their own channels.
Which is the best eSIM for El Salvador?

What to look for in an eSIM for El Salvador
- Coverage: check that El Salvador is on the plan's country list. Our El Salvador plans cover El Salvador only. Going on to Guatemala or Honduras? See the section on neighbouring countries below.
- Data and days: both are on the plan page. A small plan fits a few days in San Salvador. For a week or two with maps, ride and booking apps and video calls, look at a bigger one.
- Speed: our El Salvador plan details list 4G/LTE speed.
- A local number: most travel eSIMs are data-only. If you must call hotels, drivers or tour operators on a normal Salvadoran number, a local carrier fits better.
- Setup before you fly: you get a QR code by email and install it on Wi-Fi at home. Your phone must support eSIM and be unlocked (see how to check eSIM compatibility).
How much data do you need in El Salvador?
These are the sizes on our El Salvador eSIM page, with what each one lasts:
- El Salvador 1GB and 3GB: 1 GB or 3 GB for 3 days. A stopover or a short visit.
- El Salvador 5GB and 10GB: 5 GB or 10 GB for 7 days. A week with maps, messages and photos.
- El Salvador 20GB: 20 GB for 15 days. Two weeks, with some video.
Staying longer than 15 days or running low? Top-ups are available. Not sure how much you need? Pick the bigger size. Our guide to eSIM data plans shows how to estimate it, and how to reduce data usage abroad helps you make it last.
How does an El Salvador eSIM connect?
You don't pick the network yourself: the plan's settings use automatic network selection, with data roaming turned on for the eSIM. The eSIM activates by itself when you reach El Salvador, and you have 1 year to start using it.
Signal still varies by place, whichever eSIM you use. It can be weaker on volcano hikes, in the mangroves of the Bahía de Jiquilisco or on quiet stretches of coast. Download offline maps before you head out (Google Maps: download areas offline). The official tourism site says Wi-Fi hotspots are easy to find in business centers, hotels, coffee shops and restaurants (El Salvador Travel: about El Salvador), which helps you save data.
Local eSIM or travel eSIM?
You have two kinds of choices in El Salvador. Here is what the local carriers say on their own pages.
- Claro offers eSIM on prepaid and postpaid lines across El Salvador. In its online store you choose eSIM as the SIM type when you buy a phone or a postpaid plan without a phone, and the QR code comes by email (Claro El Salvador: eSIM).
- Movistar offers postpaid, prepaid and business eSIMs. For prepaid, you download the eSIM by scanning the QR code on its eSIM page, one prepaid eSIM per device, then activate it online or by dialling *119 from the eSIM. Postpaid lines go through its WhatsApp channel (Movistar El Salvador: eSIM).
Both give you a Salvadoran number, but both pages are written for local customers, in Spanish. A travel eSIM is different: you buy it online, compare the sizes in English, scan a QR code at home and have data the moment you land.
Choose a local eSIM if you stay a long time and need a Salvadoran number for calls. Choose a travel eSIM if you want data on arrival and a plan you can pay for before the trip. You can keep your home number active next to it (Apple: Using Dual SIM with an eSIM), see how to set up a dual eSIM.
Travel eSIM or roaming with your home carrier?
Most readers of this guide come from the USA, Canada and the UK. Before you travel, check whether your home plan includes El Salvador and what it costs per day or per gigabyte. Apple's advice is the same: check with your carrier whether international roaming is included or sold as a travel pass (Apple: Use eSIM while traveling). If it isn't included, a data-only travel eSIM is usually the simpler choice. We compare both in international roaming vs travel eSIM.
Which eSIM for San Salvador, Suchitoto or El Tunco?
You don't need a different eSIM for each place. An El Salvador plan covers the whole country, so the same eSIM works in the capital, in the colonial town of Suchitoto, on the Surf City beaches and on the volcanoes around Santa Ana.
- San Salvador: the capital and the usual starting point. Maps, ride apps and messages need little data.
- Suchitoto: the tourism board places it 47 kilometres from the capital and suggests staying the night rather than a single day trip (El Salvador Travel: Suchitoto). Handy to have data for directions and bookings.
- El Tunco and Surf City: El Tunco, 7 kilometres west of Puerto de La Libertad, is the country's best-known surf beach, and buses and vans leave from there to other Central American destinations (El Salvador Travel: El Tunco). Uploading surf videos uses much more data, so go for 10 GB or more.
- Santa Ana Volcano (Ilamatepec) and Coatepeque Lake: the tourism board calls the hike up Ilamatepec challenging, with views of Coatepeque Lake from the top (El Salvador Travel: nature and adventure). Save your map offline before you start.
Visiting Guatemala or Honduras too?
None of our regional plans, other than global ones, includes El Salvador, so an El Salvador plan works in El Salvador only. For a trip across a border, buy a country eSIM for each stop. You can install both at home and switch to the second one when you cross. Check the country list of any plan before you buy, and see our guide to eSIM providers in Guatemala if Guatemala is next.

How do you get an eSIM for El Salvador?
- Check your phone: it must support eSIM and be carrier unlocked. On iPhone, go to Settings > General > About and look for "No SIM restrictions" next to Carrier Lock (Apple: Unlock your iPhone).
- Buy and install on Wi-Fi: you get a QR code by email. Our install guide walks you through it.
- Turn on the eSIM when you land: turn on data roaming for the El Salvador eSIM, and use it as your data line so your home line doesn't run up roaming charges. Our guide to the correct roaming settings for an eSIM shows how.
