Cairo: Strong 4G/LTE coverage is standard across Greater Cairo, including the Giza plateau and tourist districts like Khan el-Khalili. The Cairo Metro has cellular service on most station platforms, but connections are often lost between stops on deeper, underground lines. Indoor coverage can be weaker in basements of large malls or within older, thick-walled buildings.

Alexandria: You'll find reliable 4G service throughout the city, with particularly strong signals along the Corniche waterfront and around key sites like the Bibliotheca Alexandrina. As a dense urban center, coverage is broadly consistent, though you may experience slower speeds inside some older, heavily constructed buildings in the city's interior.

Luxor: The main city on the East Bank, encompassing the Luxor and Karnak temples, has good 4G coverage. On the West Bank, the signal is generally stable around the entrances to major sites, but expect to lose all connectivity when you descend into the tombs in the Valley of the Kings. Service can become spotty in the rural areas between monuments.

Sharm El Sheikh: This popular resort town offers excellent 4G connectivity concentrated in the main tourist hubs like Naama Bay and throughout the hotel zones. Signal is very reliable for typical holiday use. Be prepared for the connection to weaken significantly or disappear entirely if you venture on excursions into the surrounding Sinai desert or mountainous regions.

Major Desert Highways: The primary highways connecting Cairo with Alexandria (Cairo-Alexandria Desert Road), Ismailia, and Suez maintain generally consistent mobile coverage. Signal is reliable along these busy corridors but can weaken in the most remote desert sections between major interchanges.

Nile Valley Corridor: When traveling by road or Egyptian National Railways (ENR) train along the Nile between Cairo, Luxor, and Aswan, you can expect fairly stable connectivity. The signal is strongest in the towns and cities along the river but may experience brief, intermittent drops in the agricultural areas between them.

Red Sea Coastal Roads: The main road connecting coastal cities like Hurghada, Safaga, and Marsa Alam offers good service within the resort towns. However, be prepared for signal to weaken or drop completely for extended periods on the long, undeveloped desert stretches between population centers.

Sinai Peninsula: Coastal resort areas such as Sharm El Sheikh and Dahab have excellent coverage. As you travel inland into the mountainous central region, for example towards Saint Catherine's Monastery, mobile signal becomes extremely sparse and is frequently unavailable for long portions of the journey.

Western Desert Routes: Journeys to and between the oases, such as Siwa, Bahariya, and Farafra, cross vast expanses of desert with no cellular service. While connectivity exists within the main oasis towns, the hundreds of kilometers of road connecting them are complete dead zones.

Suez Canal Tunnels: Expect a complete loss of mobile signal while transiting through long under-water crossings like the Ahmed Hamdi Tunnel, which runs beneath the Suez Canal. Service is typically restored immediately upon exiting the tunnel.
