Best eSIM for Bulgaria in 2026: Plans, Prices and Coverage Compared

HOLASIM is the best overall eSIM for Bulgaria in 2026, offering global coverage in 200+ destinations, including unlimited data plans, a never-expiring eSIM, and 24/7 human support in multiple languages, all starting from an affordable ~USD 1.70.

Bulgaria is one of the better-connected countries in south-eastern Europe, and that is good news if you are landing in Sofia with nothing but a boarding pass and a phone. Three national operators — A1 Bulgaria, Yettel (the network formerly branded Telenor) and Vivacom — cover the country with dense 4G and a 5G footprint that, according to Opensignal's January 2026 Bulgaria report, now reaches 82–86% availability depending on the operator. Sofia, Plovdiv, Varna and Burgas are genuinely fast; the Black Sea resort strip is well served; and the weak spots are where you would expect them, in the Rila and Pirin mountain valleys.

The catch is who pays for that connection. If your SIM was issued inside the EU, Bulgaria is covered by Roam Like At Home and you can stop reading. If you are travelling from the UK, the US, Australia, Brazil or anywhere in Latin America, you are not covered, and your home carrier will happily charge you a daily pass that costs more than a week of local data. That is the gap a travel eSIM fills, and Bulgaria is a cheap market: 1GB for a week starts around ~USD 1.50–3.50, and 10GB for a month can be had for ~USD 11–16.

The best eSIM for Bulgaria in 2026

Best overall: HOLASIM

Price: from ~USD 1.70 · Unlimited: Yes · Devices: iOS/Android

Reasons to buy:

• Coverage in 200+ destinations, so the same eSIM works on the rest of a multi-country trip
• The eSIM never expires — install once, top it up for each new trip
• 24/7 support staffed by real people in English, Spanish and Portuguese
• Instant QR activation, usually working before you leave the gate
• Unlimited-data plans available alongside cheaper fixed-data bundles

Reasons to avoid:

• Unlimited plans cost noticeably more than fixed-data bundles from budget rivals
• If you only ever travel to one country, a single-country specialist may undercut it

HOLASIM wins here on the thing that actually matters after your first trip: you are not buying a disposable profile. Most eSIM stores sell you a plan that dies when the validity window closes, taking the eSIM with it and forcing a fresh install next time. HOLASIM's profile stays on the phone, so a return trip to Bulgaria — or a hop to Greece, Romania or Turkey — is a top-up rather than a new setup. Combined with genuinely multilingual human support, it is the least stressful option for travellers who are not fluent in troubleshooting APN settings at 1am.

Best for unlimited data: Holafly

Price: from ~USD 20.50 (5 days) · Unlimited: Yes (only) · Devices: iOS/Android

Reasons to buy:

• Unlimited data on every plan, with no GB counter to watch
• Hotspot sharing included (~1GB/day shareable)
• Very large review base — around 4.5–4.7 on Trustpilot across its domains

Reasons to avoid:

• No fixed-data option at all, so light users overpay badly
• Fair-use throttling kicks in after roughly 3–5GB/day in independent testing
• Short trips work out to ~USD 4/day, several times the cost of a 3GB bundle

Holafly is the right answer for one specific traveller: the person who streams, video-calls and tethers a laptop and does not want to think about it. For a week of heavy use it is competitive. For a weekend in Sofia where you mostly need maps and Bolt, it is poor value.

Best budget: Saily

Price: from ~USD 1.99 (1GB/7d) · Unlimited: Yes (daily-cap tiers) · Devices: iOS/Android

Reasons to buy:

• Among the cheapest credible options for Bulgaria — ~USD 4.99 for 3GB/30d, ~USD 11.99 for 10GB/30d
• Clean app, straightforward install, hotspot allowed
• Strong reputation — around 4.7 on Trustpilot

Reasons to avoid:

• Its "unlimited" tiers are really 5GB/day with throttling afterwards, and start around ~USD 18.99
• 5G availability is not clearly stated per country

Saily, run by the team behind NordVPN, has become the default budget recommendation for European destinations, and Bulgaria is no exception. If you know roughly how much data you use, the fixed bundles are hard to beat on price.

Best for 5G and heavy monthly use: Ubigi

Price: from USD 6 (3GB/15d) · Unlimited: Yes (USD 39/30d) · Devices: iOS/Android

Reasons to buy:

• Backed by NTT Group infrastructure, with consistently good 5G attachment
• The 30-day unlimited plan at ~USD 39 is the cheapest true month of unlimited we found
• Large plan ladder up to 50GB/30d for around ~USD 34

Reasons to avoid:

• Entry pricing is less aggressive than Saily or aloSIM for tiny data needs
• Interface and account flow feel more telco than consumer app

For a month in Bulgaria — a common pattern for remote workers drawn by low costs and fast fibre in Sofia — Ubigi's monthly unlimited works out near ~USD 1.30/day, which nothing else here matches.

Best marketplace experience: Airalo

Price: from ~USD 4.00 (1GB/3d) · Unlimited: Yes (3GB/day FUP) · Devices: iOS/Android

Reasons to buy:

• The largest catalogue, with local, regional and global plans in one account
• Airmoney cashback of 5–10% depending on lifetime spend
• Around 4.1 on Trustpilot from roughly 45,000 reviews — a very large, well-tested base

Reasons to avoid:

• Per-GB pricing is rarely the cheapest for Bulgaria specifically
• Unlimited plans throttle to 1 Mbps after 3GB/day

Airalo is the safe, boring choice, and there is nothing wrong with that. If you want one account that will also cover Japan next spring, the scale is worth a small premium.

Best for tethering a laptop: Nomad

Price: from ~USD 4.50 (1GB/7d) · Unlimited: Yes (3–10 day tiers) · Devices: iOS/Android

Reasons to buy:

• Tethering explicitly supported, which matters if the phone is your office
• Deep plan ladder to 50GB/30d for around ~USD 45
• Around 4.3 on Trustpilot

Reasons to avoid:

• Mid-tier bundles cost more than Saily for the same data
• Unlimited plans throttle to 512kbps once the daily allotment is used

How to choose

Work backwards from three numbers. First, how many days you are in Bulgaria: under four days, buy a small fixed bundle, because no unlimited plan pays off that fast. Second, how much data you actually use — check Settings on your phone for last month's figure and halve it, because hotel and café Wi-Fi will carry a lot of the load. Third, whether Bulgaria is the only stop. If you are also crossing into Greece, North Macedonia, Serbia or Romania, a regional or global eSIM like HOLASIM's will beat buying four country plans.

One more filter: if you are travelling for work and will tether a laptop, rule out any provider that is vague about hotspot policy. HOLASIM, Nomad and Saily are explicit about allowing it.

How to install an eSIM in Bulgaria

1. Check compatibility before you fly. You need an unlocked, eSIM-capable phone — broadly iPhone XS/XR or newer, Google Pixel 3 or newer, and most Samsung Galaxy S20/Note20 flagships onward. A carrier-locked handset is the single most common reason an install fails.
2. Buy the plan while you still have Wi-Fi, ideally at home the night before. You cannot install an eSIM without an internet connection, and Sofia Airport Wi-Fi is not something to depend on.
3. Scan the QR code or use the provider's app. On iPhone this is Settings → Cellular → Add eSIM; on Android, Settings → Network & Internet → SIMs → Add eSIM.
4. Label the profile something obvious like "Bulgaria data" so you do not switch off the wrong line later.
5. On landing, turn on data roaming for the travel eSIM only, and leave your home line on but with data roaming off so you still receive calls and SMS.
6. Set the travel eSIM as your default for cellular data, and keep your home number as default for calls and iMessage.
7. If nothing connects after ten minutes, toggle airplane mode, then manually select A1, Yettel or Vivacom under network selection.

Coverage and networks in Bulgaria

A1 Bulgaria is the speed leader — Opensignal's January 2026 report put its average download around 113.9 Mbps, with 5G averages near 343.9 Mbps. Yettel leads on 5G availability at roughly 86% of the time, ahead of A1 and Vivacom at about 82.5%. Vivacom wins on raw coverage breadth, which makes it the more forgiving choice on the Black Sea coast and in smaller inland towns.

In practice, most travel eSIMs roam onto one or two of these rather than all three, and the provider rarely lets you choose. Sofia, Plovdiv, Varna, Burgas and the Sunny Beach strip are strong on any of them. Bansko, the Rila Monastery road and the higher Pirin trails thin out across all three networks — that is terrain, not carrier choice, so download offline maps before you head into the mountains regardless of which eSIM you buy.

FAQ

Do I need an eSIM in Bulgaria if I have an EU SIM?

No. Bulgaria is in the EU and Roam Like At Home applies, so an EU-issued SIM roams at domestic rates. Travellers from the UK, US, Canada, Australia, Brazil and Latin America do not get this and should buy an eSIM.

Is there 5G in Bulgaria?

Yes, on all three national operators, with availability around 82–86% depending on network. Whether you actually get 5G depends on your eSIM provider's roaming agreement as much as on coverage.

How much data do I need for a week in Bulgaria?

For maps, messaging, ride-hailing and light social media, 3GB comfortably covers a week. If you stream video on the go or tether a laptop, budget 10GB or move to an unlimited plan.

Can I keep my WhatsApp number while using a Bulgarian eSIM?

Yes. A data-only travel eSIM does not change your phone number. WhatsApp, Telegram and iMessage keep working over data on your existing account.

Will an eSIM work on the Black Sea coast and in Bansko?

On the coast, yes, reliably. In Bansko and the surrounding mountains, coverage is patchier on every network, so expect gaps on trails and in valleys.

Can I use the eSIM again on my next trip?

With most providers, no — the profile dies with the plan. HOLASIM is the exception here: the eSIM never expires, so you keep the profile and simply top it up for the next destination.
