Bulgaria pairs low prices with solid mobile coverage, so staying online is cheap and simple whether you are in Sofia, Plovdiv or along the Black Sea beaches. As an EU country, Bulgaria is covered by the bloc’s roaming rules, meaning any EU SIM or eSIM works here at home rates.
Networks & coverage
Three operators serve Bulgaria: A1 Bulgaria, Yettel (formerly Telenor) and Vivacom. All three offer strong 4G coverage nationwide, with 5G live and expanding across Sofia and other major cities. Coverage along the coast and main highways is reliable, though some mountain and rural areas drop to 4G or 3G.
eSIM or physical SIM?
All three Bulgarian carriers support eSIM, and international travel brands like Airalo and Nomad offer Bulgaria eSIMs you can install before you land. A physical prepaid SIM is still worth buying in-store or at Sofia Airport if you want a local number or a specific tourist data bundle, but an eSIM is the quickest route for short trips.
Data, calls & messaging
Local tourist SIMs from Yettel, A1 and Vivacom typically bundle data with national and EU minutes and SMS, and Vivacom even sells coast-friendly tourist packs with EU-wide allowances. International eSIMs are usually data-only, so calls and texts go through WhatsApp, Viber or similar apps. EU-wide regional eSIMs also work in Bulgaria with no roaming surcharge.
How much data do you need?
For light use such as maps and messaging on a short trip, 3-5 GB covers it. A beach holiday or week-long stay with photos, video calls and streaming is better served by 10-15 GB. Heavy users, remote workers or month-long visitors should aim for 20-30 GB or an unlimited Europe plan.

How we compile this data
Plan data is compiled from the public pricing pages of mobile operators, MVNOs, and eSIM providers serving each destination.
Listings are reviewed by the DROAM telecom desk and kept neutral — we surface a representative sample of options rather than promote any single provider.
Operators change allowances and pricing frequently, so we update entries as plans change and always link out to the provider for the current offer.
