eSIM for Slovenia: your questions
How much does an eSIM for Slovenia cost?
Plans for Slovenia start at £1.99 for 0.49 GB · 1 day. There are 10 plans to choose from, valid from 1 day to 30 days.
What is the best Slovenia eSIM for a one-week trip?
For 7 days in Slovenia, the best value is 3 GB · 7 days at £2.99: enough for maps, messaging, ride apps and social media. If you stream, make video calls or work online, take 10 GB · 30 days for £5.99.
Which eSIM should I get for two weeks in Slovenia?
For 14 days in Slovenia, the best value is 5 GB · 15 days at £3.49: enough for maps, messaging, ride apps and social media. If you stream, make video calls or work online, take 20 GB · 30 days for £9.49.
Is there 5G in Slovenia?
Yes, in major cities. Elsewhere in Slovenia you get 4G/LTE, which is fast enough for maps, video calls and streaming. Your eSIM uses 4G/LTE, and 5G where the partner network allows it.
Do WhatsApp and FaceTime calls work in Slovenia?
Yes. Voice and video calls on WhatsApp, FaceTime, Telegram and similar apps work normally over the eSIM data in Slovenia.
Do I need to register a SIM or show my passport in Slovenia?
No. Your eSIM is bought online and needs no passport check or registration in Slovenia.
Will my eSIM work as soon as I land at Ljubljana (LJU)?
Yes. Install the eSIM at home, switch it on when you land at Ljubljana (LJU), and it connects to a local network within a minute or two. You can order a ride or message your hotel before you leave the airport.
Where does the eSIM work in Slovenia?
Coverage is strong in Ljubljana, Bled, Piran, and Bovec and along main roads. Signal can be weak or absent in remote areas such as Triglav National Park: download offline maps before you go.
Do I need an eSIM in Slovenia if I have an EU phone plan?
Slovenia is part of the EU “Roam like at home” area, so EU and EEA plans can use their data there at no extra cost, within a fair-use limit. A travel eSIM is worth it if your plan’s roaming allowance is small, if your plan is from outside the EU, or for long stays.
Can I use the same eSIM in Slovenia and nearby countries?
Yes. Regional plans (Europe, Balkans, and Global Lite) cover Slovenia and other countries on one eSIM, so you do not need a new one at each border.
Which mobile networks does the eSIM use in Slovenia?
The eSIM connects to A1 Slovenia and Telemach Slovenia and switches to the best available network automatically.
How much data do I need for a week in Slovenia?
For maps, messaging and social media, 1 to 3 GB per week is usually enough. If you make video calls, stream or work online, choose 5 GB or more, or an unlimited plan.
Can I buy my Slovenia eSIM before I travel?
Yes, and it is the best option: install it at home over Wi-Fi. The plan only starts when your phone first connects to a network in Slovenia.
Will WhatsApp still work with my usual number?
Yes. WhatsApp stays linked to your number. Keep your regular SIM on for calls and SMS if you want, and use the eSIM for data.
