Best eSIM for Bulgaria 2026: 13 Providers Compared

A1, Vivacom and Yettel run 5G across Sofia, Plovdiv and the Black Sea resorts, and outside the deep Rila, Pirin and Rhodope ranges a visitor to Bulgaria rarely loses signal. Bulgaria offers the mountains and monasteries around Sofia, the Roman and Revival streets of Plovdiv, and the beaches and nightlife of the Black Sea coast. Getting around runs on good data for maps and messaging, and an eSIM is the cleanest way to get it: install before you fly, land at Sofia, and your phone connects to a fast network the moment you switch it on.

A1, Yettel or Vivacom: Bulgaria's 2025 nPerf ranking

Bulgaria's three networks are close, and all three are fast. In the nPerf 2025 mobile barometer, covering the whole of 2025, A1 came first with 103,596 nPoints and a median download speed of 187.43 Mbps. Yettel, the former Telenor network, was second (99,192 nPoints, 150.56 Mbps) and Vivacom third (90,729 nPoints, 136.81 Mbps).

Those are city-dominated averages, but the gap between networks is small enough that the plan's validity and data allowance matter more than the operator name. The networks are licensed by the Communications Regulation Commission, and each Simsima plan lists the ones it uses in the plan details.

Roam like at home: when an EU visitor needs nothing extra

If your SIM comes from an EU country, Iceland, Liechtenstein or Norway, you already roam in Bulgaria at your domestic price, as the EU's Your Europe roaming guide explains. Calls, texts and data are covered, with a fair-use limit on data that some operators set below your home allowance. Check that limit before you buy anything.

Visitors from the UK, the US, Turkey or Serbia are in a different position: their carriers charge international roaming in Bulgaria, often as a daily pass. For them, a Bulgaria eSIM or a Europe plan is the simpler route, and the same applies to an EU visitor whose fair-use allowance is too small for the trip.

Best eSIM plans for Bulgaria

Bulgaria has fast, cheap EU mobile data, so eSIM prices are very low and allowances go a long way. Simsima runs on the local networks with transparent pricing. Here is how a light 1 GB pack compares across eSIM providers:

If you would rather not track your usage, Bulgaria also has unlimited-data eSIMs, with speed reduced after a daily high-speed allowance until the next day. Here is how the unlimited plans compare:

Simsima's full Bulgaria lineup runs from small packs up to larger monthly allowances on the fast local networks. Because data is so cheap here, a 3 to 5 GB plan comfortably covers most trips, and heavier users pay little to size up. Many Bulgaria eSIMs also work across the wider EU if your trip continues.

Rila, Pirin and the Black Sea: signal on a Bulgaria route

In Sofia, Plovdiv, Varna and Burgas, and along the coast from Sunny Beach and Nessebar to Sozopol, coverage is dense and 5G is common. Veliko Tarnovo, Koprivshtitsa and the main highways are well covered too, as is the ski town of Bansko.

The mountains are where signal fades. Rila Monastery itself is covered, but the Seven Rila Lakes trail and the high ridges of Pirin above Bansko have patches without service. In the Rhodopes, the gorges around Trigrad and the Devil's Throat cave lose signal in the valley floors. Download the trail map before you set off.

Data for a week: Sofia, Plovdiv and Veliko Tarnovo

A popular week starts with two nights in Sofia and a day trip to Rila Monastery, then two nights in Plovdiv's old town and two in Veliko Tarnovo, with a bus or train between each. Maps, bus timetables, restaurant searches and messaging use around 300 to 400 MB a day.

• A week of city sightseeing and messaging: about 2 to 3 GB
• Add a few days on the Black Sea coast with social media and streaming by the pool: 5 GB
• Two weeks or remote work: 10 GB or more, or an unlimited plan from the table

How to install your Bulgaria eSIM

Installation takes a couple of minutes and is best done at home on Wi-Fi before you fly. The plan activates on its own when it connects to a local network on arrival, so the validity window does not start early.

1. Buy your Bulgaria plan on Simsima and open the confirmation with your QR code
2. On your phone, go to Settings, then Mobile or Cellular Data, and choose Add eSIM
3. Scan the QR code or use the one-tap install link, then label the plan Bulgaria
4. Keep your home line as default for calls and texts, and set the eSIM for data
5. Turn on data roaming for the eSIM line only, then land in Sofia and go online

Downsides of an eSIM in Bulgaria

• No Bulgarian number: Sofia taxi companies and some guesthouses still confirm by phone, so share your WhatsApp number instead
• EU visitors may be paying twice: if your home plan already roams in Bulgaria at domestic prices, a travel eSIM only makes sense when your fair-use allowance is too small
• Your phone must support eSIM and be carrier-unlocked before you fly to Sofia or Varna
• Hotspot use depends on the plan, so check the plan details before you tether a laptop
