eSIM in Bosnia and Herzegovina: which plan to choose in 2026?

How does an eSIM work in Bosnia and Herzegovina, and is my phone compatible?

An eSIM is a digital SIM card built into your phone that downloads a mobile profile instead of requiring a plastic card. After purchasing a plan, the provider usually sends you a QR code, an installation link or activation through its app. You can purchase and install this profile from France over Wi-Fi, then use it for data only once you arrive in Bosnia and Herzegovina.

Unlike a physical SIM, an eSIM requires no tray to open, no card replacement and no search for a sales point at Sarajevo Airport. It contains the same type of network information as a conventional SIM: your device connects to a local partner, provides Internet access and uses the data included in your plan. A travel eSIM is usually data-only: it gives you access to the web, but not necessarily a new Bosnian number for standard calls.

On a recent phone, you can use the Dual SIM feature: your French card remains active for your usual number, while the eSIM handles mobile data while you travel. This is very convenient for keeping your WhatsApp conversations, receiving an SMS verification code or remaining reachable on your French line. However, making or receiving calls and SMS on your French SIM may trigger your operator’s roaming charges; the eSIM does not automatically prevent them.

The key point is that your device must be both eSIM-compatible and unlocked. A phone purchased from an operator is often unlocked nowadays, but this is not universal, particularly with certain older or business devices, or phones bought abroad. An eSIM will not work if the phone is locked to another network, even if the model technically has an eSIM chip.

• iPhone: iPhone XR, XS and newer models generally support eSIM; however, check the device’s regional version, as some models sold outside Europe have specific limitations.
• Samsung Galaxy: many Galaxy S, Z Fold, Z Flip and several recent Galaxy A models are compatible. Open Settings, then Connections and SIM Manager to see whether the option to add an eSIM appears.
• Google Pixel: Pixel 3 and later generations are generally equipped for eSIM, with some exceptions depending on the country of sale. In Settings, look for Network & Internet, then SIMs.
• Other brands: several recent Motorola, Xiaomi, Oppo, Honor, Huawei and Fairphone models, as well as certain compatible iPads and Windows PCs, have eSIM support, but availability varies by exact model.
• Quick check: dial *#06# and look for an EID line, or check your SIM settings. An EID usually confirms the presence of an eSIM chip, but does not by itself guarantee that the device is unlocked.
• Before payment: check the model number in your settings and consult the compatibility list from your chosen provider; do not rely solely on your phone’s commercial name.

Should you choose a Bosnia and Herzegovina eSIM or a regional Balkans plan?

A national eSIM is generally the best choice if your trip takes place entirely in Bosnia and Herzegovina, as it focuses your budget on one country and may offer more data for the same validity period. This is suitable for a stay in Sarajevo, a Mostar–Blagaj–Jajce loop or a holiday on the Neum coast. However, check that the plan covers the whole country rather than just an imprecisely defined area.

A Balkans or Southeastern Europe plan becomes more attractive as soon as you cross a border. Common itineraries combine Bosnia and Herzegovina with Croatia, Montenegro, Serbia, Slovenia, Albania or North Macedonia. A journey from Dubrovnik to Mostar and then to Kotor, for example, involves several country changes: a single regional eSIM avoids buying and reinstalling a profile at every stop.

Be especially careful at borders. Bosnia and Herzegovina is not part of the European Union, so the European principle of included roaming does not automatically apply to your French plan or to a plan marketed simply as European. Read the exact list of covered countries, the amount of data available in each and any regional roaming rules. A worldwide plan covers more destinations, but is often less competitive in price per gigabyte than a local or Balkans offer.

• Bosnia and Herzegovina only: choose a local eSIM if you are not leaving the country and want to maximise your data allowance.
• Croatia, Montenegro or Serbia: choose a Balkans offer if you cross one or more land borders during the same trip.
• Air stopovers: check whether your plan covers the transit country, especially if you have to wait for a long time outside the international zone.
• Nearby border: disable automatic data if you are staying near Croatia, Montenegro or Serbia, to avoid accidentally connecting to an excluded network.

What do travellers think of eSIMs for Bosnia and Herzegovina?

Traveller feedback is generally positive when the eSIM is installed before departure and the plan genuinely matches the itinerary. The most frequently mentioned advantage is being able to call accommodation, find an ATM, check a map or book transport as soon as you leave the plane, without looking for a shop or handling your main SIM card. The ability to monitor usage from an app is also appreciated.

Criticism mainly concerns unrealistic expectations. Some travellers expect 5G everywhere, while Bosnia’s terrain makes performance uneven outside cities. Others install their eSIM at the last minute without Wi-Fi, forget to enable data roaming on the eSIM line or leave their French card selected as the data line. These issues look like a breakdown but often result from a simple setting.

Support is an important criterion, especially if you arrive late in Sarajevo or travel without another connection. Choose a provider that clearly lists its partner networks, validity start date, top-up rules and an accessible contact method. A slightly cheaper offer can cost time and cause stress if its instructions are vague or tethering is restricted without being clearly stated.

• What travellers like: instant purchase, fast connection after landing and the ability to keep the French SIM in the phone.
• Actual coverage: very satisfactory in cities and on classic routes, but more irregular in mountainous regions.
• Common mistake: confusing profile installation with plan activation, as these can sometimes be separate steps.
• Important point: read the validity, hotspot and top-up rules before using even a single megabyte.

Can I keep my number, make calls and share my connection with an eSIM in Bosnia and Herzegovina?

Yes, you can generally keep your French number while using a travel eSIM for Internet access thanks to Dual SIM mode. Set the eSIM as the mobile data line and leave your usual SIM active only if you need to receive SMS messages. Disable roaming data on the French line and, if your phone allows it, disable automatic cellular-data switching so it does not change lines when the signal varies.

Most travel eSIMs are data-only: they provide neither a Bosnian number nor standard calls or SMS. This does not prevent you from communicating. WhatsApp, Signal, Telegram, Messenger, FaceTime Audio, Skype and Wi-Fi calls work over data while keeping your current WhatsApp number. You do not need to create a new WhatsApp account: the app remains linked to your French number as long as you do not change it in the settings.

Tethering works with many eSIMs, but it is not universally guaranteed. Check this before buying if you need to connect a computer, tablet or someone else’s phone. A hotspot uses data very quickly: a professional video call, system update or computer streaming can consume in one hour what your phone alone would use over several days. Some plans may restrict this feature or limit speeds.

When your allowance is nearly empty, first use your hotel’s Wi-Fi to check the app and buy a top-up. Do not assume you can purchase exactly the same plan again: some providers offer a top-up, while others require a new plan or profile. Monitor both the phone’s counter and the provider’s counter, as they may show a slight difference. Once the allowance is used up, the connection is normally cut off rather than charged outside the plan, but confirm this in the terms.

• Set the eSIM as the default data line and disable cellular data on your French SIM before take-off.
• Keep your number for WhatsApp: the app works over the Internet regardless of which line provides the data.
• For bank verification codes by SMS, leave the French SIM active, but avoid outgoing calls and check incoming-call charges with your operator.
• Enable the hotspot only when necessary and prevent automatic updates on the connected computer.
• Install the provider’s app and set an alert at 75% and 90% usage to avoid running out while travelling.
