📊 The comparison at a glance
Prices checked in September 2026 on official websites — they change regularly, double-check before buying.
- 🥇 Simplest (unlimited data): Holafly — unlimited plans from $19.90 for 3 days, 24/7 support. Best for short trips.

- 🥉 Cheapest per GB: a local Claro or Tigo SIM (~$2-5 for the chip + top-up) — unbeatable for long stays.
📶 Holafly: the easiest unlimited eSIM
Holafly is the benchmark for all-inclusive travel eSIMs: a single unlimited data plan for El Salvador, from 3 to 90 days, set up in minutes on the Holafly website or app.
- Data: unlimited, on 4G/LTE and even 5G where available.
- Prices checked (September 2026): 3 days $19.90; 5 days $28.90; 7 days $36.50; 10 days $39.50; 15 days $53.50; 30 days $106.50; 90 days $300.90. The daily rate drops significantly with longer durations (prices may change).
- Local networks: Tigo, Movistar and CTE Telecom Personal.
- Activation: the plan starts when you connect to a Salvadoran network, not at installation.
- Support: 24/7 chat assistance.
- Hotspot: 1 GB per day shareable with your other devices.
- Limitations: data only (no local number — calls go through WhatsApp).
Who is it for? Trips of one to three weeks where you want zero hassle: scan the QR code, land, browse. It costs more per GB than a local SIM, but peace of mind has a price.

💳 Airalo, Saily, Nomad: serious alternatives
Other reliable platforms now offer El Salvador-specific eSIMs — sometimes cheaper than Holafly on long unlimited plans.
- Airalo — dedicated El Salvador eSIM (Movistar network): unlimited data at $19/3 days, $35/7 days, $49/15 days and $99/30 days, plus fixed-data plans from $5.50. Its regional “Latin America” eSIM starts at $7, the Global one at $8.50. Polished app, easy top-ups.
- Saily: from $5.99 (1GB/7 days), 3, 5 and 10GB tiers on 30 days plus an unlimited option; the Latin America eSIM (12 countries) starts at $7.99.
- Nomad: from $6 on the Claro network, 7-to-30-day plans to activate within 60 days of purchase; the Latin America regional plan drops to about $3.25/GB.
- MobiMatter: a marketplace with often the lowest prices, but minimal support.
Who is it for? Light users (1-3GB per week) or travelers crossing Guatemala, Honduras and El Salvador on a single regional eSIM.
🏪 eSIM or local Claro/Tigo SIM?
El Salvador has some of the cheapest mobile service in Central America. A prepaid chip costs about $2-5 at an official store (passport required) and a $5-10 top-up easily buys several GB for 30 days — Claro and Tigo usually include WhatsApp and social networks at no extra data cost.
- Pros: unbeatable price per GB, a local number (handy for bookings), top-ups available everywhere (supermarkets, pharmacies).
- Cons: queueing at the store, paperwork in Spanish, mostly physical SIMs (in-store eSIM exists at some carriers), and you may need to swap out your usual SIM if your phone takes only one line.
⚙️ Compatibility and setup: sort it out before you fly
- eSIM-compatible phone: iPhone XS/XR or newer, Pixel 3+, Samsung Galaxy S20+ and recent Android equivalents.
- Unlocked phone: a device bought with a carrier plan must be carrier-unlocked.
- Install before departure: the QR code or app install usually requires Wi-Fi, not mobile data.
- Keep your physical SIM active to receive bank SMS: the eSIM works as a data-only line.
- Turn off roaming on your home plan to avoid surprise charges when you return.
📡 Network coverage: the key point
Travel eSIMs connect to Salvadoran networks depending on the provider: Tigo and Movistar for Holafly, Movistar for Airalo, Claro for Nomad. All cover cities, the coast (El Tunco, El Zonte) and tourist corridors well in 4G. In rural areas — El Imposible National Park, some mountain villages — the signal weakens here and there, whichever eSIM you pick. 5G remains limited to San Salvador and the biggest cities: a bonus when available, not a deciding factor.
🏁 Our verdict by traveler profile
- One-to-two-week trip, simplicity first: the Holafly unlimited eSIM — ready to go, 24/7 support, no surprises. Tight budget on unlimited: Airalo's 30-day plan at $99.
- Budget traveler or long stay: a local Claro/Tigo chip + monthly top-ups.
- Central America backpacking: an Airalo (from $7) or Saily (from $7.99) regional eSIM covering several countries.
- Heavy user (digital nomad): local SIM as the main line + an eSIM as backup.
