Best eSIM for Tashkent in 2026
— Ranked by Real Performance

Tashkent sits on an improving but uneven 4G LTE network, anchored primarily by Ucell (Coscom) and Beeline Uzbekistan, with UMS (a joint venture with MTS Russia) rounding out meaningful coverage across the capital's 2.8 million residents. For business travellers and long-stay visitors, connectivity is generally solid in central districts and major hotels, but rural excursions beyond the Tashkent region quickly expose the patchwork nature of national coverage. Critically, most international eSIM providers roaming into Uzbekistan route via Ucell as their preferred wholesale partner — meaning your real-world experience depends heavily on which operator your eSIM is actually peered with, not just which brand you bought.

• →Ucell (Coscom), majority-owned by TeliaSonera, holds approximately 38% of Uzbekistan's mobile subscriber base and provides the most consistent 4G LTE footprint within Tashkent city limits — making it the preferred wholesale roaming anchor for international MVNOs.
• →Tashkent's metro system (Toshkent metropoliteni) has no consistent mobile signal through most of its 29 underground stations; the deeper Blue Line stations such as Kosmonavtlar and Pushkin are effectively dead zones for data — plan offline maps accordingly.
• →Uzbekistan operates under a national telecommunications regulator (UzACI) that mandates all roaming traffic be declared and can, in practice, throttle unrecognised MVNO routes — a factor that occasionally causes the first 24–48 hours of an eSIM activation to feel slower than steady-state speeds.
• →Peak 4G LTE download speeds on Ucell in central Tashkent typically reach 25–40 Mbps in favourable conditions, but average real-world throughput measured across tourist zones (Chorsu Bazaar, Amir Timur Square, Old City) sits closer to 8–14 Mbps due to network congestion and legacy spectrum allocation in the 1800 MHz band.
