Frequently Asked Questions About eSIM
Everything about virtual SIM cards for travel
Does eSIM work in Slovenia?+
Yes, Slovenia is in the EU, and eSIM providers offer stable coverage through local operators A1, Telekom Slovenije, and Telemach.
Can I use a European SIM card?+
Yes, Slovenia is part of EU roaming. If you have a SIM from any EU country, it will work at no extra cost. An eSIM is an alternative if you don't have one.
Is there coverage in the mountains?+
Valleys and resorts (Bled, Bohinj, Kranjska Gora) have good 4G coverage. Signal may drop on high-altitude trails in Triglav National Park.
How much does an eSIM for Slovenia cost?+
A European eSIM package costs from €5–8 for 5 GB over 7 days. Since Slovenia is in the EU, any Europe-wide eSIM plan will work – no need for a Slovenia-specific plan.
Where can I buy a local SIM card?+
At A1 and Telekom Slovenije stores in any city. Tourist packages cost from €10–15 for 20 GB. For short trips, eSIM is more convenient.
How can I check whether my phone supports eSIM?+
Dial *#06#: if the screen shows an EID number, the phone supports eSIM. On iPhone you can also look for "Add eSIM" in Settings → Cellular; on Android — in Settings → Connections (or Network) → SIM manager. Or find your model in our list.
Which phones support eSIM?+
iPhone XS / XR and all newer models, Google Pixel 3 and newer, Samsung Galaxy S20 and newer plus the Z Fold and Z Flip series, and most recent flagships from Xiaomi, OPPO, Motorola and Huawei. Exceptions: iPhones sold in mainland China have no eSIM, and some budget versions of Android models skip it — check the exact model.
Will an eSIM work on a carrier-locked phone?+
No. A phone locked to one carrier will not accept another provider's eSIM. Ask your carrier to unlock it before the trip — check under Settings → General → About → Carrier Lock on iPhone, or by inserting a SIM from another carrier on Android.
What if my phone does not support eSIM?+
Buy a local physical SIM card on arrival (usually at the airport or a carrier shop, with your passport), use a pocket Wi-Fi router, or rely on your home carrier's roaming package. A local SIM is often the cheapest for long stays.
Why use an eSIM instead of roaming or a local SIM?+
An eSIM gives you mobile data from the moment you land: no hunting for a shop at the airport, no passport registration and no roaming bills from your home carrier. You buy and install it online before the trip, and your main SIM stays in the phone for calls and texts.
What do I need to use an eSIM?+
A carrier-unlocked phone that supports eSIM, an internet connection to install the profile (hotel or home Wi-Fi is fine) and a bank card for payment. Not sure about your phone? Check it in a minute.
How do I choose an eSIM provider?+
Look at four things: which local network the eSIM uses, how many gigabytes you need, how long the plan is valid and the price per GB. Compare plans for your destination side by side, or answer a few questions and we will suggest a plan.
When should I install the eSIM?+
Install it at home over Wi-Fi a day or two before departure, but switch the eSIM line on only when you land: turn on data roaming for the eSIM line and set it as the line for mobile data. Most plans start counting days from the first connection abroad, not from purchase.
Can I keep my main SIM card active?+
Yes. Phones with eSIM work in dual-SIM mode: keep your main SIM for calls and SMS (bank codes still arrive) and use the eSIM for data. To avoid roaming charges, turn off mobile data on the main line.
How do I remove an eSIM after the trip?+
Delete the eSIM profile in your phone settings (Cellular / Mobile network → the eSIM line → Delete). It does not affect your main SIM card. If you might top up the same eSIM on your next trip, you can simply switch the line off instead.
