Cheapest unlimited eSIM for Bulgaria? From €5.50 for 3 days (October 2026)

If you’re travelling to Bulgaria and want connectivity without restrictions, Roam2Go’s unlimited eSIM starts from €5.50 for 3 days — an option designed for long weekends, city breaks in Sofia, or trips to the Black Sea Riviera. If your SIM is from outside Europe (USA, UK, Latin America, Asia), this eSIM saves you from nasty international roaming charges and gives you a fixed price in euros from the very start.

Who is an eSIM for Bulgaria useful for?

Bulgaria is a member of the European Union, which means travellers with a mobile plan from a European operator usually have “roam like at home” included. If that’s your situation, you may not need a local eSIM — or perhaps you do, if you want unlimited data without eating into your home plan’s allowance.

On the other hand, if you’re travelling from the United States, the United Kingdom, Canada, Latin America or Asia, international roaming can be prohibitively expensive or simply not included in your contract. This is where a Roam2Go eSIM makes all the difference: activate the plan before you leave, arrive in Sofia, and you’ll have data straight away — no further setup needed.

Roam2Go unlimited plans for Bulgaria (3, 5 and 7 days)

Roam2Go offers unlimited plans for Bulgaria across a range of durations. The three most popular for short or medium stays are the 3, 5 and 7-day options:

• 3 days — €5.50: perfect for a weekend in Sofia, Plovdiv or Varna.
• 5 days — €7.95: ideal for a short break or combining two cities.
• 7 days — €10.99: the go-to choice for a full week in the country.

All unlimited plans work with a daily high-speed data allowance; once that allowance is reached, the connection remains active but at a reduced speed until the allowance renews the following day. There is no service cut-off at any point.

If you’re planning a longer stay, we also offer unlimited plans for 10, 15 and 30 days (at €14.50, €19.95 and €27.95 respectively). Check the product page to see all the options.

How to choose the right plan for your trip to Bulgaria

If you’re a moderate user (maps, messaging, occasional social media)

A fixed-data plan is usually sufficient. For stays of up to a week, plans such as 1 GB or 3 GB for 7 days tend to cover everyday use without overspending. It largely depends on whether you allow apps to update in the background or whether you stream video.

If you’re a heavy user (live navigation, video, work video calls)

An unlimited plan is the obvious choice. Knowing you won’t run out of data in the middle of the Rila Mountains or on the beach at Sunny Beach is well worth the peace of mind it brings. For a full week, the 7-day plan at €10.99 is what most travellers with a heavy usage profile would go for.

If you’re combining Bulgaria with other countries in the region

Check on the product page whether the Bulgaria plan also covers the neighbouring countries you’ll be visiting. If not, it may be worth considering a regional plan. You’ll find all the options at the Bulgaria page on Roam2Go.

How to activate your Roam2Go eSIM for Bulgaria

The process is straightforward and requires no technical knowledge. Purchase the plan from the Roam2Go shop, receive the instructions by email, and scan the QR code from your phone’s settings. The connection activates automatically once you land in Bulgaria.

If you’ve never installed an eSIM before, you can read the step-by-step guide for iPhone at how to activate an eSIM on iPhone or the equivalent guide for Android at how to activate an eSIM on Android.

One important reminder: your phone must be eSIM-compatible and SIM-unlocked. Most modern devices meet these requirements, but you can verify yours using our compatible devices guide.
