Our comparison below ranks every eSIM plan for Bulgaria by price per GB, data allowance and network coverage — updated automatically whenever plans change.
Plans are ranked by a combination of real traveler usage, pricing, data value, and coverage reliability. Rankings update automatically as providers change their offerings.
Bulgaria is one of the Balkans' most visited destinations, offering a mix of ancient Thracian history, Black Sea beaches, mountain ski resorts and vibrant cities. As an EU member state, Bulgaria has a well-developed mobile network operated by three carriers: Vivacom, A1 Bulgaria (formerly Mobiltel) and Telenor Bulgaria. All three operators have strong 4G networks — Vivacom leads in overall national coverage and is the network most used by international eSIM plans. 5G has been launched commercially, with live coverage in Sofia, Plovdiv and several other major cities. EU roaming rules technically apply to EU-issued SIM cards used in Bulgaria, but a dedicated travel eSIM often offers better data rates for non-EU visitors and more flexibility for all travellers.
A travel eSIM is the fastest way to get connected — no SIM shop, no roaming charges, and your home number stays active.

Most travel eSIMs are data-only — and that covers 90% of travelers perfectly. WhatsApp, FaceTime, and Google Voice handle calls and video seamlessly. Some providers do offer plans with a local Bulgaria number if you genuinely need one.
Not sure which plan to pick? Here's what we recommend based on your travel style:
Sofia has excellent 4G and 5G coverage — the Alexander Nevsky Cathedral, Vitosha Boulevard, the Archaeological Museum, Boyana Church and all central neighbourhoods have strong connectivity. Navigation apps, Bolt (ride-hailing) and translation tools all work seamlessly. A 3 to 5 GB plan for 5–7 days is ideal for a Sofia city break.
All three major ski resorts have solid 4G coverage from Vivacom and A1 Bulgaria in resort towns and on the main slopes. Lift queues and après-ski are well covered. Only the highest off-piste areas may have weaker signal. A 5 to 10 GB plan for 7–14 days covers a typical ski holiday.
Varna and Burgas have excellent 4G and 5G coverage. The entire Black Sea coastline including Sozopol, Nessebar and Golden Sands has strong coverage. A 5 GB plan for 7–10 days is comfortable for a beach holiday.
The main cultural circuit (Sofia → Rila → Plovdiv) has very good coverage throughout. Rila Monastery itself and the surrounding valley are covered. Higher Rila mountain trails have patchy signal — download maps before heading up. A 5 GB plan for 7–10 days covers the full cultural circuit.
Sofia has a growing co-working scene with cafés and workspaces in the city centre. Bulgaria is one of the most affordable EU capitals for digital nomads. Fast 4G/5G is available everywhere. An unlimited or 20+ GB monthly plan on Vivacom or A1 is the best choice for extended remote work stays.
Bulgaria has 3 major mobile operators: Vivacom, A1 Bulgaria, Telenor Bulgaria. All offer nationwide 4G coverage, with 5G now available in major cities.
4G speeds in Bulgaria average 25 to 60 Mbps download — fast and reliable across all tourist destinations. Sofia, Plovdiv, Varna, Burgas, Borovets and Bansko all have excellent coverage. The Rose Valley, Rila Monastery circuit and Black Sea coast are all well covered. Mountain areas (Pirin, Rhodopes, Balkan Range) have good coverage in resort towns and valleys but may weaken on high peaks and remote trails. The Rhodope mountains and Danube valley are fully covered. Vivacom and A1 both provide reliable urban and suburban performance.
Most travel eSIM providers use Vivacom or A1 Bulgaria infrastructure in Bulgaria — both consistently ranked among the best networks in the region. You'll get strong, reliable signal in all major tourist areas.
Bolt (ride-hailing) is widely available in Sofia and major cities — significantly cheaper than taxis and requires mobile data.
Bulgaria has completely open internet — all standard social media, WhatsApp, Google and travel apps are freely accessible.
Bulgaria has excellent hiking in the Rila, Pirin and Rhodope mountains — coverage in resort towns and valleys is good, but high ridgelines can be patchy.
Bulgaria uses the Bulgarian Lev (BGN) — despite being EU, Bulgaria has not adopted the Euro (expected in 2025–2026).
Vivacom is the most popular network for travel eSIMs in Bulgaria and offers the best overall coverage including rural areas.

For most travellers, Saily and Airalo (Vivacom network) offer the best balance of price and coverage. MobiMatter is specifically highlighted for Bulgaria with prices as low as $0.30 per GB.

Vivacom has the best national coverage, particularly in rural areas and mountain regions. A1 Bulgaria is excellent in cities and suburbs. Telenor Bulgaria also has strong urban coverage. For most travel itineraries, Vivacom is the recommended choice.
Yes — Bulgaria has launched commercial 5G services. Coverage is available in Sofia, Plovdiv and several major cities on Vivacom and A1 networks. 5G is expanding progressively. For most travel purposes, 4G in Bulgaria is fast and reliable — 5G is a bonus in the major urban centres.
Yes — Bulgaria is an EU member state. EU roaming rules (Roam Like at Home) apply to EU-issued SIM cards, meaning EU citizens may use their home plan's data in Bulgaria without extra charges (subject to fair use limits). However, non-EU travellers benefit most from a dedicated travel eSIM, which often provides better data rates.
For a 7-day Bulgaria trip (Sofia + Plovdiv or Black Sea): 3 to 5 GB covers standard use — maps, Bolt, social media and light streaming. For a ski trip (10–14 days at Bansko or Borovets): 5 to 10 GB is comfortable. For a longer cultural circuit including the monasteries and Rhodopes: 5 to 8 GB for 10 days.
Excellent coverage in Bansko resort town and on the main ski slopes. Both Vivacom and A1 have solid 4G in the Bansko valley. Higher off-piste areas may have reduced signal. Coverage is generally reliable enough for all standard ski resort use — maps, messaging, weather apps and Bolt bookings all work well.
iPhone XS (2018) and later, Samsung Galaxy S20+, and most Google Pixel 3+ all support eSIM in Bulgaria. The country uses LTE bands 3, 7, 20 and 28. Your device must be carrier-unlocked. Check our compatibility list for your specific model.
MobiMatter is specifically praised for Bulgaria in the Reddit travel community, offering prices as low as $0.30/GB. Saily also offers competitive rates. For unlimited data, Holafly is an option. For a multi-country Balkan trip, look for a Balkans regional plan that covers Bulgaria, Greece, Romania and Turkey in one package.
Yes — Rila Monastery and the surrounding valley have reliable Vivacom 4G coverage. The monastery is a major tourist destination and the network is solid for navigation, photography and communication. Hiking trails into the higher Rila mountains above the monastery have patchier signal — download trail maps offline before ascending.
Bulgaria punches well above its weight as a travel destination — excellent 4G and growing 5G infrastructure mean you'll be connected from Sofia's museum quarter to the ski slopes of Bansko. Whether you're a light or heavy data user, there's an eSIM plan that fits your trip perfectly.
