Stay Connected in San Salvador

Connectivity in San Salvador beats expectations. The city runs solid 4G LTE across the metro area, with 5G rolling out in zones like Escalón, Santa Elena, and around the Zona Rosa. Good news first. Prepaid SIMs are cheap, kiosks sit on every corner, and the dollarized economy means no currency-conversion math when topping up. The frustrating part: coverage thins fast once you head toward the volcano routes, El Boquerón, or coastal escapes like El Tunco. Hotels and cafes in trendy neighborhoods push their WiFi hard as a selling point, only for it to buckle the moment a few guests start streaming. As of now, San Salvador rewards travelers who set up mobile data before they need it, rather than leaning on patchy public networks. Set it up early. A working SIM or eSIM tends to be the difference between a smooth trip and a frustrating one.

Three carriers dominate San Salvador. Those are Tigo, Claro, and Movistar. Tigo tends to be the strongest performer in the capital, with the widest 4G LTE footprint and the most aggressive 5G rollout in upscale districts like Santa Elena, Escalón, and along the Boulevard del Hipódromo. Claro lands a close second, reliable in the historic centre and around the airport corridor, and locals often recommend it for travel beyond the capital toward Santa Ana or San Miguel. Movistar has decent urban coverage but tends to lag once you leave San Salvador proper. Real-world speeds in the metro area typically land between 30 and 80 Mbps on 4G, with 5G zones pushing well past 200 Mbps when you're standing in the right spot. Video calls work fine. Most cafes and hotels handle them well, though older buildings with thick walls get the occasional dropout. Coverage gets spotty once you're climbing toward El Boquerón or driving the coastal road to La Libertad. Fair warning on day trips.

Public WiFi in San Salvador, whether at the airport, in hotel lobbies in Escalón, or at cafes around Zona Rosa, runs on the same security assumptions as anywhere else. Assume the network is unsecured. Assume someone could be watching. Travelers tend to be targets because they're often logging into banking apps, checking email, and connecting to networks they'll never use again, which makes credential harvesting low-risk for attackers. A VPN like NordVPN encrypts your traffic between your device and its servers, so even if someone is sniffing the cafe network, they see scrambled data rather than your login details. Worth installing one before you arrive. Above all if you'll be working remotely or moving money. Hotel WiFi tends to be marginally safer than fully public networks. But not by enough to skip the precaution.
