Best eSIM for Bulgaria: Plans, Prices and 5G Coverage
July 26th, 2026
TL;DR
The cheapest Keep On Roaming plan for Bulgaria is the Roam Like Home® Bulgaria 1 GB 7 Days at £4.50, a sensible pick for a light-use city break. If you measure value by price per gigabyte, the Bulgaria 100 GB 30 Days at £47.00 comes out lowest at £0.47 per GB, with the 50 GB 30 Days a whisker behind at £0.48 per GB. For a typical one or two week trip, the 10 GB 30 Days at £13.00 sits in the comfortable middle. Every plan connects to Yettel Bulgaria, Vivacom and A1 Bulgaria, with speeds up to 5G.
What to look for in a travel eSIM for Bulgaria
Coverage. Bulgaria's cities are easy, but if your plans include mountain hikes or Black Sea road trips, you want an eSIM that can use more than one local network. Keep On Roaming plans in Bulgaria connect to Yettel Bulgaria, Vivacom and A1 Bulgaria, all supporting 2G, 3G, 4G and 5G, so your phone can pick the strongest signal wherever you are.
Plan flexibility. Think honestly about how long you are going and how you use your phone. A weekend in Sofia needs far less than a month working remotely from Plovdiv. Look for a range that covers both fixed-data plans and unlimited options, so you are not paying for data you will never touch.
Top-ups. Trips run long and data runs short. With Keep On Roaming you can top up an existing eSIM with more data from your account dashboard, without installing a new eSIM, which saves you fiddling with QR codes halfway through your holiday.
Installation before you fly. The best time to set up your eSIM is at home on good Wi-Fi, not in an arrivals hall. You install via QR code before you travel, and the eSIM activates when you arrive and connect. You land, your phone finds a Bulgarian network, and you are online.

A few honest pointers from the numbers. On the fixed-data side, the price per gigabyte falls steadily as you go up: £4.50 per GB on the 1 GB plan, £1.30 per GB at 10 GB, £0.48 per GB at 50 GB, and £0.47 per GB at 100 GB. So the bigger plans reward heavy users, but there is no shame in the small ones if you mostly need maps and messages.
The unlimited plans suit travellers who would rather not think about data at all. They start at £6.50 for a single day and run up to £16.00 for 10 days, £18.50 for 15 days and £35.00 for a full 30 days. If you stream video, hotspot-free navigation all day, or upload a lot of photos, an unlimited plan removes the guesswork.
Whichever you choose, you connect to the same three networks, Yettel Bulgaria, Vivacom and A1 Bulgaria, each offering 2G, 3G, 4G and 5G.
Frequently asked questions
Will my phone work with an eSIM?
Most recent smartphones support eSIM, but check two things before you buy: that your specific model has eSIM support (you will find this in your phone's settings or the manufacturer's specifications), and that your phone is unlocked. A phone locked to your home carrier may refuse to use another provider's eSIM.
When should I install my eSIM?
Before you leave home. You install the eSIM via QR code before you travel, ideally on reliable Wi-Fi, and it activates when you arrive in Bulgaria and connect to a network. That way you are online the moment you switch off flight mode.
What happens if I use up my data?
You can top up your existing eSIM with more data from your account dashboard. There is no need to buy and install a new eSIM, so a top-up takes moments even mid-trip.
Will my phone number change?
No. These plans are data-only, and your existing SIM, number, calls and texts keep working alongside the eSIM. You browse on Bulgarian data while staying reachable on your usual number.
Which networks will I be using in Bulgaria?
Keep On Roaming plans connect to Yettel Bulgaria, Vivacom and A1 Bulgaria. All three support 2G, 3G, 4G and 5G, so you get the best speeds your phone and location allow.
What if my trip is longer than my plan?
You have two options: pick a longer plan up front (fixed-data plans run up to 30 days, as do the unlimited plans), or top up from your dashboard as you go. For open-ended trips, starting with a 30-day plan and topping up is usually the simplest route.
