Bulgaria: Mobile Coverage & Carriers
Bulgaria's mobile market is served by three major carriers: A1, Yettel, and Vivacom. All three networks support 3G and 4G/LTE services. 5G has been commercially launched in the country, though specific coverage details remain limited. Roaming eSIMs typically connect via LTE bands B20 (800 MHz), B3 (1800 MHz), and B7 (2600 MHz), with 5G roaming expected to use the n78 band (3.5 GHz) where available.
Some local Bulgarian carriers issue eSIMs, though availability and adoption vary by provider. Users considering eSIM activation in Bulgaria should verify current eSIM support directly with their chosen carrier, as the landscape continues to develop.
