Addis Ababa: As the capital, Addis Ababa offers the most reliable 4G/LTE coverage in the country. Signal is strong in central areas like Bole, Meskel Square, and around major tourist sites. The Addis Ababa Light Rail has good connectivity at stations, but the signal can be intermittent on underground sections between stops. Indoor coverage in modern hotels and malls is generally good, but can be weaker in older, denser buildings.

Gondar: You can expect solid 4G and 3G coverage throughout central Gondar, especially around the Royal Enclosure of Fasil Ghebbi. Connections are generally stable for navigation and basic browsing. Signal strength may decrease slightly inside the thick stone walls of the historic castles or in some older guesthouses.

Lalibela: Connectivity in the town of Lalibela is generally adequate with 3G and some 4G service, sufficient for maps and messaging. However, due to the unique nature of the main attractions, expect to lose signal completely when you are inside the subterranean rock-hewn churches. Coverage is best in open areas and within the town itself.

Bahir Dar: The city of Bahir Dar enjoys good 4G coverage, particularly along the Lake Tana shoreline and in the main commercial districts. Service is reliable in most hotels and restaurants. Be aware that mobile signal will become weak or unavailable during boat excursions to the monasteries on the lake's islands, especially the further you travel from the shore.

Major Roads and Expressways: The Addis Ababa-Adama Expressway generally offers consistent and reliable mobile signal. On other major routes like the A1 to Djibouti, A2 towards Gondar, or A3 to Bahir Dar, coverage is strong in and around cities and larger towns but frequently becomes intermittent or drops out completely in the vast rural landscapes between them.

Ethio-Djibouti Railway: Connectivity along this modern railway line is best near major stations such as Addis Ababa, Adama, and Dire Dawa. Travelers should anticipate signal loss in remote sections, particularly when passing through the Awash Valley and the numerous tunnels along the route.

Ethiopian Highlands and Mountain Passes: Driving through mountainous regions like the Simien or Bale Mountains will result in significant periods without a mobile signal. High-altitude passes and winding roads, such as the Limalimo Pass north of Gondar, are known for having little to no network coverage.

Tunnels and River Gorges: Expect to lose your connection when passing through any significant road or railway tunnel. Deep river valleys also present challenges; for example, signal is often lost when descending into and crossing the Blue Nile Gorge on the A3 highway, with service returning on the ascent.

Remote and Border Regions: Vast areas of Ethiopia have extremely limited or non-existent mobile networks. This includes the Danakil Depression, much of the Lower Omo Valley, and large parts of the Somali, Afar, and Gambela regions. Travel to these areas requires preparation for being offline for extended durations.
