Using your UK phone in Bulgaria
Yes. On Simp+ and Simp Pro, your UK eSIM works in Bulgaria the way it does at home: data comes out of your Europe allowance, 10GB a month on Simp+ and 20GB on Simp Pro, and calls and texts to UK numbers come out of your usual UK allowances. There is nothing extra to buy.

How it works in Bulgaria.
Your speed there, and what to do before you go. Most of the time it is nothing.
How fast it is
In Europe, your UK eSIM runs at the same speeds as in the UK, with no extra speed limit: 5G is typically 100 to 250Mbps down and 10 to 25Mbps up, and 4G typically 20 to 50Mbps down and 5 to 15Mbps up. Bulgaria is in Europe, so that is what you get there.
Before you go
Nothing to install and nothing to switch on: your UK eSIM roams in Bulgaria on its own.
You can roam in Europe on up to 15 days in each billing month. From day 16, roaming in Europe on your UK eSIM is suspended until your next billing month starts.
Calls and texts to UK numbers come out of your usual UK allowances. International calls are not possible.
What it costs.
Roaming in Bulgaria is in the price of the plan: Simp+ from £10 a month and Simp Pro from £13 a month. There is no daily charge, no pass to buy and no bill for data waiting when you get home. Top-ups are only if you want them.
Your Europe allowance stops when it is used, until it renews, and it is not topped up. Roaming 5G data top-ups are for your global roaming eSIM, which works in Europe too, so you can carry on with that. Each is bought in the app and valid for 30 days.
One-off, so nothing renews on youGood to know in Bulgaria.
The emergency numbers, a few things about your phone there and some travel notes, each from an official source.
Emergency numbers
- 112: ambulance, fire, police
Your phone there
- Romania and Greece are in the same Europe allowance, so crossing over changes nothing.
- Turkey, Serbia and North Macedonia are outside Europe on our list, so your data there runs on the global roaming eSIM. Install it from the app before you go.
Travel notes
- In summer and early autumn, Bulgaria is on a regular alert for wildfires.
- For skiing, mountaineering and other mountain sports, your insurance should cover mountain rescue and helicopter costs.
- The country has a comprehensive rail network, but trains can be cancelled at short notice.
- You must drive with sidelights or dipped headlights on, even in the daytime.
- People who live in Great Britain made 657,000 visits to Bulgaria in 2024, the Office for National Statistics estimates.
Questions about roaming in Bulgaria.
Does my UK phone work in Bulgaria?
Yes. On Simp+ and Simp Pro, your UK eSIM works in Bulgaria the way it does at home: data comes out of your Europe allowance, 10GB a month on Simp+ and 20GB on Simp Pro, and calls and texts to UK numbers come out of your usual UK allowances. There is nothing extra to buy.
How much data do I get in Bulgaria?
10GB a month on Simp+ and 20GB on Simp Pro, from your Europe allowance. You can roam in Europe on up to 15 days in each billing month. From day 16, roaming in Europe on your UK eSIM is suspended until your next billing month starts. It is one allowance for every destination in Europe, not one per country.
What happens when my data runs out in Bulgaria?
Data stops when your Europe allowance is used, until it renews. It never slows down first. If you need more, your global roaming eSIM works in Europe too, and its 5G data can be topped up in the app.
Can I call UK numbers from Bulgaria?
Yes. Calls and texts to UK numbers come out of your usual UK allowances, the same as at home. International calls are not possible.
Do I need to do anything before I go to Bulgaria?
No. Your UK eSIM roams on its own, with nothing to install and nothing to switch on.
Will I pay extra to use my phone in Bulgaria?
No. Roaming is in the price of Simp+ and Simp Pro, so there is no daily charge and no bill for data when you get home. Roaming 5G data top-ups are optional.
