FairSIM eSIM for Bulgaria
Bulgaria is a country of long drives and small screens. Sofia to Plovdiv is under two hours on the A1, the Black Sea coast is another three, and Bansko sits behind a mountain pass. Between them you will be reading Cyrillic road signs, booking a rural guesthouse that only answers on Viber, and checking whether the bus to Veliko Tarnovo leaves from the central station or the one across the road. All of that runs on data.
A FairSIM eSIM roams onto A1, Yettel or Vivacom, the three national networks, all of them running 5G in the cities and 4G LTE nearly everywhere else. You install it over Wi-Fi before you fly, switch the line on at Sofia or Burgas airport, and skip the queue for a prepaid SIM that needs your passport and a form. Four plan sizes are on sale for Bulgaria, so a ski week and a month of remote work do not cost the same.
One local rule to know: paid street parking in Sofia and the coastal towns has traditionally been paid by SMS from a Bulgarian mobile number, which a data eSIM cannot send. Use the parking app, a machine, or an attendant instead. The same goes for highways, where an e-vignette is compulsory for cars and is bought online or in the BGTOLL app, not at a tollbooth.

Bulgaria eSIM plans
Plan starts: On first data use
Coverage in Bulgaria
- 4G LTE5G
A1
The largest operator, with 5G across Sofia, Plovdiv, Varna, Burgas and the main resorts, and dense 4G along the motorways and in the villages.
- 4G LTE5G
Yettel
Formerly Telenor Bulgaria, with towers run by Cetin. Strong 5G in the cities and solid 4G on the coast and in the ski valleys.
- 4G LTE5G
Vivacom
The former incumbent, now part of United Group. Wide rural 4G reach thanks to its legacy footprint, plus 5G in the larger towns.
5G in Sofia, Plovdiv, Varna, Burgas and the bigger resorts, with 4G LTE as the national fallback
Typical speed: Fast enough for video calls, maps and streaming on 5G in the cities, and comfortable 4G speeds on the motorways and along the coast. Expect congestion in Sunny Beach and Bansko at the peak of the season.
Coverage follows the roads and the towns. The A1, A2 and A3 motorways, the whole Black Sea strip, Sofia, Plovdiv, Veliko Tarnovo, Ruse and the ski resorts are well served. Gaps appear on hiking trails in Rila, Pirin and the central Rhodopes, on the Seven Rila Lakes route, and in deep valleys near the Greek and Serbian borders.
How much data do you need in Bulgaria?
It depends on how you travel. Find your trip below, then pick the plan that matches. You can always top up in the app.
Black Sea beach week
Sunny Beach, Golden Sands, Sozopol or Nessebar with a rented apartment.
Why data matters: Apartment check-in instructions, beach bar menus by QR code, ferry and water park tickets, and a lot of photo uploads. Networks get busy in August evenings.

Sofia and Plovdiv city break
Four or five days between two cities on the train or the A1.
Why data matters: Google Maps and Moovit for trams and metro, Bolt or TaxiMe instead of haggling, restaurant bookings on Viber, and translating Cyrillic menus with the camera.

Bansko or Borovets ski trip
A week of lifts, lessons and après in the Pirin or Rila mountains.
Why data matters: Lift status, weather and avalanche updates, ski school messages, and transfer drivers who confirm the pickup by text. Your phone drains fast in the cold.

Monasteries and mountains road trip
A hire car from Sofia to Rila, the Rhodopes, Veliko Tarnovo and back.
Why data matters: Offline maps as backup, the BGTOLL e-vignette bought before you reach the motorway, fuel stops, and guesthouse owners who answer on Viber rather than email.

Remote work month in Sofia or Plovdiv
Cheap rent, good coffee and a long stay on a laptop.
Why data matters: Calls on Teams and Zoom, Personal Hotspot when the flat Wi-Fi drops, and daily deliveries. A month-long plan is the honest choice here.

How FairSIM works
Three steps between you and the internet abroad. Nothing to pick up at the airport.
Pick a destination and a plan
Choose the country or region and the data you need. The price you see is the price you pay.
Tap install
On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.
Land and connect
Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.
Connectivity tips for Bulgaria
Install and test the eSIM at home over Wi-Fi, then switch the line on and turn on data roaming after you land. Validity usually starts at the first connection to a Bulgarian network.
Buy the motorway e-vignette in the BGTOLL app or online before you leave the airport if you have a hire car; there are no tollbooths and fines are issued by camera.
Do not rely on SMS parking in Sofia's blue and green zones with a foreign data eSIM. Use a parking app, a machine or an attendant.
Learn to read a few Cyrillic letters, or keep Google Translate camera mode handy. Many small-town signs and menus have no Latin version.
Download offline maps for Rila, Pirin and the Rhodopes. Trails and mountain passes lose signal even where the nearest town has 5G.
Carry a power bank on ski days and long coastal drives. Cold and constant navigation both drain a battery fast.
Keep your home SIM in the phone with its data roaming switched off, so bank one-time codes still arrive.
Crossing into Greece, Turkey, Romania or Serbia? Buy the next plan in the app before you reach the border, or take the Europe regional plan instead.
Can you rely on free Wi-Fi?
Free Wi-Fi is easy to find in Sofia and Plovdiv cafes, in hotels, in shopping centres and in most guesthouses, and it is usually fast because Bulgaria has excellent fixed broadband. It is much less dependable where you actually need it: beach bars, rural guesthouses, mountain huts, buses and trains. Resort Wi-Fi in August slows to nothing once a few hundred people share it, and open networks are not the place for banking. Treat Wi-Fi as a bonus for big downloads and keep the eSIM on for everything that matters.
Local SIM card or eSIM in Bulgaria?
A1, Yettel and Vivacom all sell prepaid starter packs in their own shops, in malls, in supermarkets and at Sofia Airport Terminal 2. Bulgarian law requires identification for a prepaid line, so you hand over a passport and wait while the shop registers it. That is fine if you are staying a month and want a Bulgarian number for parking SMS and local deliveries. It is a waste of an hour if you land at 23:00 in Burgas and need a taxi.
A FairSIM eSIM runs on the same A1, Yettel and Vivacom towers, installs from home over Wi-Fi, and needs no paperwork. You keep your usual number active for bank codes on your physical SIM while data runs on the eSIM. The trade-off is honest: no Bulgarian phone number and no local voice calls, so anything that depends on an SMS from a national number still needs a local line or a workaround.
Bulgaria eSIM questions
Does eSIM work in Bulgaria?
Yes. Any unlocked eSIM-capable phone connects to A1, Yettel or Vivacom with a travel eSIM. On iPhone that means XS, XR or newer, and iOS 17.4 or later for the one-tap install.
Which network will my Bulgaria eSIM use?
A1, Yettel or Vivacom. The app shows which network each plan uses. All three run 5G in the cities and 4G nationally, and your phone will pick the strongest available signal.
Is there 5G in Bulgaria?
Yes, in Sofia, Plovdiv, Varna, Burgas, the larger towns and the main resorts. Elsewhere you get 4G LTE, which is fine for maps, calls and streaming. Your phone needs 5G support to see it.
Can I use Personal Hotspot in Bulgaria?
Yes. Every FairSIM plan supports Personal Hotspot, with no separate hotspot cap. Handy for a laptop in a guesthouse with weak Wi-Fi.
Do I get a Bulgarian phone number?
No. FairSIM is data only. Use WhatsApp, Viber or FaceTime over data for calls and messages, and keep your home SIM for SMS codes.
I have an EU SIM. Do I need an eSIM for Bulgaria?
Probably not for a short trip, since EU roaming lets you use your domestic allowance at no extra charge. Check your fair use limit if you are staying weeks or plan heavy tethering.
How much data do I need for a week in Bulgaria?
A city break on maps and messaging uses about 3 to 5 GB a week. A beach or ski week with photo uploads and some streaming is closer to 8 to 10 GB. A working month is when unlimited earns its place.
Should I install the eSIM before or after landing?
Before. Install over Wi-Fi at home, leave the line off, then enable it and data roaming at Sofia, Burgas or Varna airport. Installing on arrival needs Wi-Fi you may not have.
Local SIM or eSIM for Bulgaria?
A local A1, Yettel or Vivacom prepaid SIM gives you a Bulgarian number but needs your passport and a shop visit. A travel eSIM roams on the same three networks, installs before you fly, and needs no paperwork.
What is an eSIM?
A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.
Is my phone compatible?
FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer, on iOS 17.4 or later for the one-tap install with no QR code. iPhones bought in mainland China do not support eSIM at all, even when unlocked. Not sure yours is unlocked? Check Settings, General, About, Carrier Lock, or ask your carrier. The full list is on the How it works page.
When should I install my eSIM?
Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.
Do FairSIM eSIMs come with a phone number?
No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
