Algeria, Africa’s largest country by area, has three competing mobile operators and widespread 4G across its populated north. Travellers to Algiers, Oran, Constantine, and the coastal cities will find getting online easy, while the vast Saharan south has sparser coverage.
Networks & coverage
Three operators serve the country: Mobilis (state-owned), Djezzy, and Ooredoo Algeria. All run 4G/LTE networks concentrated along the densely populated Mediterranean coast and the northern highlands, covering Algiers, Oran, Constantine, Annaba, and the main inland cities. Coverage is good across the north but becomes patchy across the Sahara and remote desert routes, where Mobilis tends to have the widest reach.
5G is not yet generally available, so plan around a 4G/LTE experience, which is reliable in the cities and towns where most visitors travel.
eSIM or physical SIM?
Travel eSIMs from Airalo, Saily, Holafly, and others work in Algeria, typically roaming on Ooredoo. They are the simplest option for short trips — install before you fly and connect on arrival, avoiding local registration. These profiles are data-only.
For longer stays, a local physical SIM from Mobilis, Djezzy, or Ooredoo is much cheaper and gives you an Algerian number, though purchase requires your passport for registration. SIMs are sold at operator shops and outlets near Algiers’ Houari Boumediene Airport (ALG).
Data, calls & messaging
eSIM plans cover data only, so rely on WhatsApp or similar apps for calls and messages. A local prepaid SIM adds an Algerian number and generous monthly bundles — Mobilis and Djezzy both sell starter packs that include large data allowances (often 50–80 GB) plus calling credit and SMS for a 30-day cycle, which is excellent value for longer visits.
How much data do you need?
A short trip of maps, messaging, and social media needs only 1–3 GB. A week or two of regular use is comfortable on 5–10 GB. If you are staying a month or want to stream and hotspot freely, a local 50 GB+ monthly starter pack is hard to beat on price.
