Best eSIM for Bulgaria: Real Prices Compared for Sofia and the Black Sea Coast

Sofia's mix of Roman ruins and Soviet-era mosaics, the rose valleys around Plovdiv, and the Black Sea resorts at Varna and Sunny Beach make Bulgaria one of the better-value trips left in the EU — and the eSIM pricing here reflects that too. We track 120 providers carrying real Bulgaria eSIM plans, refreshed daily, so here's what the actual numbers look like today rather than a generic Europe rate.

Quick-answer picks

• Cheapest way to get connected: Yesim's 500MB / 1-day plan at $0.50 — enough to confirm your setup works before a longer trip.
• Best value for a week around Sofia or the coast: Yatelo's 1GB / 7-day plan at $1.41.
• Best full month, real headroom: Yatelo's 3GB / 30-day plan at $2.72 — more useful than the cheapest headline 30-day option (BNESIM's 1GB for $2.51), since three times the data costs barely more.
• Best price for heavy data use: MobiMatter's 100GB / 180-day plan at $29.99, working out to roughly $0.30 per GB — the strongest rate we found in the whole catalog.
• Best full-month unlimited: Maya Mobile at $49.99 for 30 days, on its flat global rate.

co:sim has by far the biggest lineup we track for Bulgaria — a genuine Unlimited day pass at $0.99 up to a 100GB/180-day plan at currently unavailable, giving you the most tier options if your trip length doesn't line up with anyone else's standard windows.

GigSky pairs a solid weekly rate ($2.99) with one of the cheapest short unlimited options around, at $3.49 for a full day. They also currently have a discount code active:

MobiMatter is the standout for anyone who actually needs a lot of data. Its 100GB/180-day plan at $29.99 works out to about $0.30 per GB — the best raw value in the entire Bulgaria catalog — and its 120GB/30-day tier at $49.99 is strong too if you want that volume inside a single month. They currently run a real discount code:

Ubigi is worth a look if you're relocating rather than just visiting — its 240GB spread over 365 days for $199.00 is a genuinely unusual annual option among the providers we track for Bulgaria. Discount code active:

Yatelo is the best all-round value pick for shorter trips — cheapest at the weekly length (1GB/7 days, $1.41) and a smarter 30-day option than the raw-cheapest alternative, since its 3GB tier costs barely more than BNESIM's 1GB.

eSIMCard sells the cheapest genuinely unlimited plan we found for Bulgaria at any length — $1.74 for a full day, a good fit if you just need one heavy-use day, like a conference or a big photo upload. Real discount code:

eSIMCard -10% ESIMKART

Maya Mobile doesn't specialise in Bulgaria — it charges the same flat unlimited rate everywhere it operates — but that rate still comes out as the best full-month unlimited price we found here: $9.99 for 3 days, $19.99 for 7 days, $49.99 for 30. Discount code active:

Global YO is a smaller catalog worth checking on longer windows — its 100GB/60-day plan at $41.39 is a genuine option if a two-month timeframe fits your trip, though MobiMatter's 100GB/180-day plan still comes out cheaper per gigabyte overall.

Why prices vary this much

A 50-cent test pass and a $199 annual plan both show up under "Bulgaria eSIM," but they're solving completely different problems. The cheapest entries here (Yesim, co:sim) are light-use day-passes — fine for messaging and maps, not built for a full day of active navigation or streaming. MobiMatter wins specifically on volume — its strength only shows up once you're buying 30GB or more, not on the smallest tiers. Maya Mobile's flat global rate means it doesn't specialise in Bulgaria at all, yet still beats every Bulgaria-specific unlimited competitor at the 30-day mark, which tells you more about how expensive unlimited pricing tends to be elsewhere than about Bulgaria specifically.

If you're not sure how much data your trip actually needs, our data usage guide is worth checking before defaulting to unlimited — most travelers use less than they think, even hopping between Sofia, Plovdiv, and the coast.

Which plan fits your trip

• A short city break in Sofia or Plovdiv: Yesim's 500MB/1-day pass, or Yatelo's 1GB/7-day plan if you're staying closer to a week.
• A week on the Black Sea coast, Varna to Sunny Beach: Yatelo's 1GB/7-day plan at $1.41 is the standard pick.
• A full month exploring further, including a Rila Monastery day trip: Yatelo's 3GB/30-day plan at $2.72 for typical use, or MobiMatter's 100GB/180-day plan at $29.99 if you want serious headroom or are staying long-term.
• Heavy data use — video calls home, constant navigation, streaming: Maya Mobile's $49.99 flat-rate month, or eSIMCard's $1.74 unlimited day-rate for a single heavy stretch.

A few practical notes

Bulgaria's an EU member but hasn't adopted the euro yet — you'll still be paying in Bulgarian lev on the ground, which has nothing to do with your eSIM pricing above but catches some travelers out. Coverage is strong across Sofia, Plovdiv, Varna, and the main Black Sea resorts; more remote mountain stretches, including parts of the Rila and Pirin ranges, can be patchier, the same limitation a local Bulgarian SIM would have.

Install your eSIM before you fly — every provider above only activates once you land and connect to a Bulgarian network, so there's no benefit to setting it up at home. If this is your first time using an eSIM at all, our beginner's guide to how eSIMs work covers installation and activation from the very start.

If your trip continues into Romania, Greece, or elsewhere in the Balkans, check each destination's pricing separately rather than assuming one plan carries over — our multi-country trip planner can show you real plans that genuinely cover your whole route if one exists.
