HelloRoam
Best Value
$5.20
5 GB / 30 days
Pros: Lowest price per GB, fast activation, Bulgaria coverage on A1, Vivacom and Telenor. Cons: Newer brand, smaller community than Airalo.
The best eSIM for Bulgaria is HelloRoam. A1, Vivacom and Telenor are the 3 networks a visitor eSIM can use in Bulgaria, and HelloRoam routes all 7 of its Bulgaria plans across all 3, so the profile moves to whichever network has signal where you stand. A1 leads on network quality in Sofia, Plovdiv, Varna and Burgas.
Vivacom is Bulgaria's national telecom and reaches smaller towns and the Rhodope mountain villages where A1 fades. Telenor holds competitive urban 4G in Sofia and Plovdiv. None of the 3 sells 5G to visitor eSIM profiles.
Coverage analysis
A1 Bulgaria provides the strongest 4G along the Black Sea coast, with uninterrupted signal on the Sunny Beach boardwalk and the coastal highway between Varna and Burgas. Vivacom is the only carrier that maintains usable 4G in the Rhodope mountain villages like Shiroka Laka and Smolyan, where A1 fades to Edge. The Rila Mountains above the Seven Rila Lakes trail lose all carrier signal past 2,200 meters, and Strandja Nature Park near the Turkish border only gets patchy 3G from Telenor along the main forest road.
Activation
Install your e-sim before landing at SOF (Sofia Airport) or VAR (Varna Airport). Scan the QR code in Settings, then Mobile Data, then Add eSIM. The profile registers on A1 after landing and hands over to Vivacom or Telenor where A1 is weak.
The Sofia Metro holds 4G at all stations on Lines 1, 2 and 3. Tethering is active on all 7 plans. EU roam-like-home rights apply in Romania, Greece and the rest of the EU on the plan tiers that carry them.
Data usage tips
Sofia navigation with Google Maps offline saves 200 MB for the city center. The Eventim app for concerts and festivals at the National Palace of Culture uses under 10 MB. Sunny Beach resort strip navigation uses 50 MB per day.
Budget 400-600 MB per day in cities for maps, messaging, and social media. Ski resort apps for Bansko piste maps work offline after a 30 MB download.

Questions about Bulgaria eSIMs
Which eSIM should I buy for Bulgaria?
+
HelloRoam sells the Bulgaria eSIM at $5.20 for 5 GB across A1, Vivacom and Telenor 4G, which covers a 5-day Sofia and Plovdiv trip. Saily charges $6.99 for the same 5 GB and Airalo charges $7.00, so the 3 sit level at that size. The 20 GB plan at $17.03 works out to $0.77/GB for a longer stay.
How much does an eSIM for Bulgaria cost?
+
HelloRoam prices 7 Bulgaria plans, starting at $2.21 for 1 GB over 7 days on A1, Vivacom and Telenor 4G. 3 GB costs $3.47, 5 GB costs $5.20, 10 GB costs $8.06 and 20 GB costs $17.03. The 20 GB tier works out to $0.77/GB, the 50 GB plan costs $38.43, and a 1-day plan costs $2.21.
How do I activate an eSIM in Bulgaria?
+
The best eSIM for Bulgaria is HelloRoam. Install the QR code before you land: open Settings, tap Mobile Data, then Add eSIM, then scan. The profile registers on A1, Vivacom and Telenor after landing and works at Sofia Airport arrivals without a store visit. Tethering is on across all 7 plans, and EU roam-like-home rights apply in neighbouring EU countries on the tiers that carry them.
How much data do I need in Bulgaria?
+
The best eSIM for Bulgaria is HelloRoam. A 5-day Sofia and Plovdiv trip uses 3-4 GB at roughly 600 MB per day for maps, transit apps and photos. A 2-week Black Sea summer holiday runs 7-10 GB if you stream from Sunny Beach without resort Wi-Fi. Bansko ski weeks use less, so budget 3-4 GB across 7 days in the mountains.
Which networks do eSIMs use in Bulgaria?
+
The best eSIM for Bulgaria is HelloRoam. Bulgaria eSIM plans reach 3 networks: A1, Vivacom and Telenor, all on 4G. A1 leads on urban quality across Sofia and the coast, Vivacom reaches the Rhodope mountain villages better than A1, and Telenor holds its own in Sofia and Plovdiv. The profile picks the strongest signal at each location without manual selection.
Does a Bulgaria eSIM include EU roaming?
+
The best eSIM for Bulgaria is HelloRoam. Bulgaria eSIM plans on A1, Vivacom and Telenor carry EU roam-like-home rights on the tiers that include them, so data works in Greece, Romania and the rest of the EU at no extra cost. Crossing into Turkey or taking the ferry out of Varna leaves EU territory and the rights stop. North Macedonia is a candidate country, not an EU member.
How good is coverage at Bansko and the Bulgarian ski resorts?
+
The best eSIM for Bulgaria is HelloRoam. A1, Vivacom and Telenor all deliver 4G at the Bansko resort base, Borovets village and Pamporovo. Lifts running to the summit at 2,560 metres weaken on all 3 networks, and the upper Todorka chairlifts have gaps. Download the Bansko piste map before you ride up, because the app needs about 30 MB.
Does my phone support eSIM in Bulgaria?
+
The best eSIM for Bulgaria is HelloRoam. Carrier-unlocked iPhones from XS onward, Pixel 3a onward and Galaxy S20 onward all connect in Bulgaria. Your device must be carrier-unlocked. Dual-SIM eSIM phones let you keep a home SIM active alongside the Bulgaria eSIM. Confirm eSIM capability in Settings, then General, then About before buying a plan.
Can I top up my Bulgaria eSIM if I run out of data?
+
The best eSIM for Bulgaria is HelloRoam. All 7 Bulgaria eSIM plans support top-up. Buy a data add-on and it lands on the same profile, with no second QR scan needed. Start with the 3 GB plan at $3.47 for a short Black Sea weekend and add data if the trip runs long, or take the 5 GB plan at $5.20 up front.
Is the Black Sea coast well covered?
+
The best eSIM for Bulgaria is HelloRoam. A1, Vivacom and Telenor both deliver 4G along the whole coastal strip from Sunny Beach to Sozopol, Nessebar and Varna. Golden Sands and Albena hold full 4G, and the coastal road between Varna and Burgas keeps signal end to end. Strandja Nature Park south of Sozopol drops to patchy 3G once you move inland.
