Stay Connected in Algiers

Connectivity in Algiers is workable but uneven, and it tends to catch travelers off guard when they expect Mediterranean-Europe smoothness. The city has solid 4G across most of the centre, Bab Ezzouar, Hydra, and along the corniche. Speeds fluctuate noticeably during business hours. Here's the frustrating part: international roaming charges from most carriers are punishing, and Algeria isn't covered by EU roam-like-home arrangements, so your French or Italian SIM will burn credit fast. The upside: local data is cheap once you're set up, and cafe WiFi in Algiers neighborhoods like Telemly and around Place Audin is usually reliable for a coffee's worth of work. The catch most visitors miss is that buying a local SIM requires passport registration, and the kiosks at Houari Boumediene Airport don't always stay open for late arrivals. Plan ahead. Sort your first 24 hours of connectivity before you land in Algiers, not after.

Three carriers cover Algiers: Djezzy, Mobilis, and Ooredoo. Mobilis is the state operator and tends to have the broadest reach, including the hillside neighborhoods above the bay where signal can otherwise drop out. Djezzy is generally regarded as the speed leader in central Algiers, around the business districts of Hydra and Ben Aknoun, and it's a decent pick if you're doing video calls. Ooredoo sits in the middle on coverage but often runs the most aggressive tourist-friendly data bundles. 4G is the practical standard. 5G has rolled out in pockets. Don't count on it. City-centre speeds typically land in a range that handles streaming and video calls fine, though you might get the occasional dropout in the Casbah's narrow streets, where the old stone walls play havoc with signal. Push outside Algiers proper, toward day-trip destinations like Tipaza or further into the interior, and coverage gets spotty fairly quickly. Fair warning. Mobilis tends to hold up best on those routes.

Hotel and cafe WiFi across Algiers is generally functional but rarely well-secured, and airport WiFi at Houari Boumediene is a particular soft target, as you'd expect from any major international hub. The risk isn't dramatic. It's mostly opportunistic credential harvesting on unencrypted networks, and travelers tend to be targets because they're logging into banking and email from unfamiliar networks while distracted. A VPN like NordVPN encrypts your traffic before it hits the WiFi router, which means even on a compromised network, what an attacker sees is unreadable. Worth using anytime you're handling banking, work email, or anything with a password you'd hate to lose. It's also useful for accessing streaming services from home that don't work cleanly from Algerian IP addresses. Turn it on at the airport. Leave it on at the hotel.
