Field tip — Check your EU/EEA fair-use policy
EU Roam Like At Home rules apply in Bulgaria, but most EU carriers impose a fair use policy (FUP) that caps the data you can roam at a fraction of your domestic allowance. A French subscriber with 100 GB/month at home may only be able to roam 20–25 GB in Bulgaria before extra charges kick in. The exact cap depends on your carrier and plan. Check the FUP limit in your carrier's roaming terms before your trip. If your stay is short and within your FUP, your EU SIM may cover you at no extra cost. If you're staying longer or have a low FUP cap, a local eSIM is more predictable.
Field tip — Bulgaria uses Lev (BGN), not Euro; download offline maps for mountain routes
Bulgaria is an EU member state but has not adopted the Euro. Bulgarian Lev (BGN) is the currency. Cards are accepted widely in Sofia, Plovdiv, Varna and Burgas, and in most resort areas. Cash in Lev is useful in smaller towns, mountain villages, local markets and rural petrol stations. ATMs (bankomat) are available in all cities and tourist areas. For the Rila Monastery circuit, the Rhodope mountains and the Vitosha massif above Sofia, download offline maps before leaving the city — signal is generally good in resorts and on main roads, but remote mountain trails and deep valley sections can have gaps.

Yettel is solid in urban centres with a lighter rural footprint.
Among the five providers on this page: Airalo (Bultel plan) and Saily route via A1 Bulgaria. aloSIM routes via all three networks (A1, Yettel and Vivacom). Roamless carrier not confirmed.

Arrival protocol in Bulgaria
Before departure from home
EU travellers: check your carrier's Bulgaria FUP limit before deciding whether to use EU roaming or buy a travel eSIM.
Check your phone supports eSIM — dial *#06#, look for an EID number.
Install the eSIM before your flight — activation is automatic on landing at Sofia Airport (SOF).
Save QR code and setup instructions offline.
Download offline maps for mountain routes (Rila, Rhodopes, Pirin) before leaving Sofia.
Keep home SIM active for calls and SMS.
After landing in Bulgaria
Go to Settings → Mobile data → select the eSIM as your data line.
If using EU roaming, turn off data roaming on your travel eSIM.
Test with a page load. If nothing loads, toggle airplane mode for 30 seconds.
Do not delete the eSIM if it does not connect immediately — check settings first.
VPN, passwords and documents
Bulgaria has no internet restrictions — a VPN is not required for standard use. On hotel or resort Wi-Fi, a VPN is useful for banking or work accounts. A password manager is helpful on the road. Keep a secure cloud backup of your passport, insurance certificate and accommodation bookings — and an offline copy, especially for mountain trips where connectivity is limited.
Mistakes to avoid in Bulgaria
Assuming Bulgaria uses the Euro. Bulgaria uses the Bulgarian Lev (BGN). Cards are widely accepted in cities and resorts, but cash in Lev is needed in smaller towns and mountain villages.
Relying on EU roaming without checking your FUP limit. EU RLAH applies, but most carriers cap roaming data significantly below your domestic allowance. A stay of 7+ days with heavy use can easily exceed the FUP cap.
Choosing Airalo or Saily for a Rila Monastery circuit or mountain trip without knowing both route via A1. For remote mountain coverage (Rhodopes, Pirin, Vitosha backcountry), Vivacom has the wider rural footprint — only aloSIM provides access to Vivacom.
Not downloading offline maps before heading into the mountains. Rila Monastery and the surrounding circuit, as well as many Rhodope and Pirin trails, have dead zones on all networks. Download in Sofia before you leave.
Yes. Bulgaria joined the EU in 2007 and EU Roam Like At Home applies for EU/EEA SIM cards. Bulgaria entered the Schengen Area in March 2024 (air and sea borders) and January 2025 (land borders). Vivacom dominates rural coverage in the Rila-Rhodope mountains, A1 leads in cities. EU/EEA SIM holders should check their fair-use cap before extended stays.
Which network is best for travel in Bulgaria?
Bulgaria has three operators: Vivacom (widest national coverage, best for rural areas and the Rila-Rhodope mountains), A1 Bulgaria (fastest speeds, best 5G in Sofia, Plovdiv, Varna and Burgas) and Yettel (solid urban coverage, lighter rural footprint). For Rila Monastery or Black Sea coastal drives, Vivacom leads rural. For Sofia city use, A1 is fastest.
Continuing your trip in Europe?
Many travellers combine Bulgaria with neighbouring countries. See our guides for eSIM in Romania, eSIM in Greece and eSIM in Turkey. For multi-country trips combining Bulgaria with neighbouring Europe destinations, our Europe regional plan comparison may be useful.
