This specific plan is valid only within Bulgaria (and the EU). This is the most important question for Balkan travelers. If you take a bus from Sofia to Istanbul (Turkey), Belgrade (Serbia), or Skopje (North Macedonia), your connection will stop at the border as they are not in the EU. For this multi-country trip, we highly recommend our Europe Regional eSIM, which covers both EU and non-EU Balkan countries.
It depends. Bulgaria is in the EU, so "Roam Like at Home" applies only to EU citizens.
- If you are from the UK (Post-Brexit): Most UK carriers (like O2, Vodafone, Three) have reintroduced daily roaming fees (e.g., £2-£6 per day).
- If you are from the USA/Canada/Asia: Your home carrier will charge expensive international rates (e.g., $10-$14 per day).
A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper than these roaming charges.
Yes, absolutely. Bulgaria has a fantastic, modern 4G/5G network. Our eSIM connects to premium local networks (like A1 or Yettel) to ensure you have a strong signal for Google Maps while hiking in the Rila Mountains, on the ski slopes in Bansko, or at the resorts on the Black Sea (Sunny Beach).
Yes, 100%. Buying a physical local SIM card (like A1, Yettel, or Vivacom) at Sofia Airport requires you to find the kiosk, wait in line, and go through a mandatory passport registration process as required by Bulgarian law. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land.
To give you the best speed and coverage, our eSIM connects to Bulgaria’s premium Tier-1 networks, typically A1, Yettel (formerly Telenor), or Vivacom. This ensures you get the fastest available 4G/LTE (and 5G) speeds, whether you are in Sofia, Plovdiv, or Varna.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
