Tashkent: As the capital, Tashkent offers strong 4G and expanding 5G coverage throughout its urban and suburban areas. Tourist districts and business centers have excellent connectivity. The Tashkent Metro provides reliable mobile signal in most stations and on platforms, though connections can become intermittent on the trains themselves, particularly on deeper, older lines.

Samarkand: You'll find excellent 4G coverage across the city, especially around major historical sites like the Registan Square, Gur-e-Amir, and Bibi-Khanym Mosque. Service is reliable for navigation and streaming. Be aware that indoor coverage can sometimes be weaker inside traditional guesthouses or restaurants constructed with very thick, historic walls.

Bukhara: Connectivity is strong and reliable throughout Bukhara's famous historic center and its modern districts. Expect consistent 4G signal while exploring the Poi Kalyan Complex, Lyabi-Hauz, and the ancient trading domes. Similar to other old cities, some thick-walled traditional buildings may slightly reduce indoor signal strength.

Khiva: Good 4G service is available within the ancient walled city of Itchan Kala and the surrounding modern town. The dense layout of the old city with its narrow alleyways and massive madrasas can occasionally create weaker signal spots, but overall connectivity for maps and communication is dependable for tourists.

Fergana: In the heart of the Fergana Valley, the city of Fergana has very good and consistent 4G coverage. As a modern administrative and industrial hub, its infrastructure supports reliable mobile data throughout the main urban area. Signal strength may vary if you travel into the more rural or mountainous areas surrounding the city.

Major Highways (M39, A380): Connectivity is generally reliable along the main M39 tourist corridor connecting Tashkent, Samarkand, and Bukhara. Expect intermittent signal drops in rural areas between cities. The A380 highway crossing the Kyzylkum Desert to Khiva has significant and prolonged periods with no service.

Afrosiyob High-Speed Rail: The modern train service linking Tashkent, Samarkand, and Bukhara offers a relatively stable connection, but the signal can weaken or drop out completely in the open countryside between major stations. Onboard Wi-Fi service, if offered, can also be inconsistent.

Kamchik Pass (A373 Highway): When traveling by road between Tashkent and the Fergana Valley, expect highly intermittent to non-existent mobile coverage while traversing the Kamchik Pass. The mountainous terrain significantly disrupts cellular signals for long stretches of the journey.

Tunnels: Major road and rail tunnels, particularly the long tunnels on the Kamchik Pass route, typically have no cellular reception inside. Service resumes promptly upon exiting.

Kyzylkum Desert: The vast and sparsely populated Kyzylkum Desert, especially on the main road between Bukhara and Khiva, is a well-known dead zone for mobile coverage. Travelers should prepare for extended periods, potentially lasting several hours, without any signal.
