FAQ
Is my phone compatible? Most phones from the last few years support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models. Check your settings for an Add eSIM option.
When should I install it? Install at home before you fly. Activation begins when you connect in Bosnia and Herzegovina, so you are online on arrival.
Can I keep WhatsApp and my number? Yes. Your number stays on your main line, so WhatsApp, calls and texts keep working while the eSIM handles data.

Does a HelloSIM eSIM work in Bosnia and Herzegovina?
Yes. HelloSIM offers a Bosnia and Herzegovina data eSIM that connects to local mobile networks, so you get data as soon as you arrive without hunting for a SIM shop in Sarajevo or Mostar.
Is my phone compatible with an eSIM for Bosnia?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3 and later, and recent Samsung Galaxy S and Note models. Dial *#06# and look for an EID number, or check your phone's settings for an 'Add eSIM' option to confirm.
How do I check if my iPhone supports eSIM before travelling to Bosnia?
On iPhone, go to Settings > General > About and scroll to look for an Available SIM or EID entry, or open Settings > Cellular and see if 'Add eSIM' appears. iPhone XS, XR and all later models support it, as long as they aren't carrier-locked.
Will a carrier-locked phone work with a Bosnia eSIM?
No. Your phone must be carrier-unlocked to use any third-party eSIM, including HelloSIM. If you bought your phone on a contract, ask your home carrier to unlock it before you travel.
Which networks does HelloSIM use in Bosnia and Herzegovina?
Bosnia's mobile market is served by BH Telecom, m:tel and HT Eronet. HelloSIM connects through local partner networks so your eSIM roams onto strong available coverage across the country.
How do I buy and install a HelloSIM eSIM for Bosnia?
Buy the Bosnia plan on the HelloSIM site, and you'll receive a QR code by email. Scan it in your phone's cellular settings to install the eSIM, ideally over Wi-Fi before you fly.
How do I install the eSIM QR code on an iPhone?
Go to Settings > Cellular > Add eSIM > Use QR Code, then scan the code from your HelloSIM email. Follow the prompts to label the line and choose it for data.
How do I install the eSIM on an Android phone?
On most Android phones go to Settings > Network & internet > SIMs > Add eSIM, then scan the HelloSIM QR code. Menu wording varies slightly by brand like Samsung, Pixel or Xiaomi.
Should I install the Bosnia eSIM before I fly or after I land?
Install it before you fly while you have reliable Wi-Fi, but wait to activate or enable data until you arrive in Bosnia if the plan's validity starts on first use. Installing early avoids doing it on airport Wi-Fi.
When does my Bosnia eSIM plan start counting down?
Most HelloSIM plans start their validity window when the eSIM first connects to a network in Bosnia, not at the moment of purchase. Check your plan details, but generally you can buy in advance without losing days.
Do I need to set the APN manually for my Bosnia eSIM?
Usually not, as the APN configures automatically when the eSIM connects. If data doesn't work, HelloSIM provides the correct APN to enter under your phone's cellular data settings.
Do I have to turn on data roaming for the eSIM to work in Bosnia?
Yes. Because the eSIM uses partner networks, you need to enable data roaming for the HelloSIM line specifically. This won't affect your home SIM as long as you toggle it only on the eSIM line.
Can I keep my home number active while using a Bosnia eSIM?
Yes. Keep your primary SIM in the phone for calls and texts on your home number, and use the HelloSIM eSIM for data. Just turn off data roaming on your home line to avoid extra charges.
Is there 4G in Bosnia and Herzegovina?
Yes, 4G LTE is widely available across cities and most towns, so you can expect solid speeds in Sarajevo, Banja Luka, Mostar, Tuzla and Zenica. Rural and mountainous areas may drop to 3G.
Is 5G available in Bosnia?
5G in Bosnia is still limited and rolling out gradually, so most travellers will use 4G LTE. Coverage and speeds on 4G are more than enough for maps, browsing and video.
What are typical mobile data speeds in Bosnia?
In cities on 4G you can commonly expect speeds good enough for HD streaming and video calls. Speeds drop in mountainous regions and remote valleys where 3G or weaker signal is more common.
How much data do I need for a week in Bosnia?
For a week of maps, messaging, social media and some browsing, many travellers are comfortable with around 3 to 5 GB. If you stream video or use lots of hotspot, consider a larger plan.
How much data should I get for two weeks in Bosnia?
For a fortnight, roughly 7 to 10 GB suits typical use like navigation, social media and light streaming. Heavy streamers or remote workers should size up or plan to top up.
How much do Bosnia eSIM plans typically cost?
Prices vary by data amount and validity, but eSIM data plans are generally an affordable, transparent alternative to standard roaming. Check the live HelloSIM Bosnia page for current tiers rather than relying on a fixed figure.
Can I use my Bosnia eSIM as a mobile hotspot?
Yes, HelloSIM data plans support tethering, so you can share your connection with a laptop or tablet. Hotspot use draws from the same data allowance, so heavier sharing uses your data faster.
Does the Bosnia eSIM include calls and SMS or is it data only?
HelloSIM plans are data-only, so they don't come with a local phone number for regular calls or texts. You can still call and message over the internet using WhatsApp, Viber, FaceTime or similar apps.
How do I make phone calls with a data-only eSIM in Bosnia?
Use internet-based apps such as WhatsApp, Viber, Signal or FaceTime over your eSIM data. Viber and WhatsApp are especially popular in the Balkans, so most local contacts use them too.
Will my eSIM work at Sarajevo Airport when I land?
Yes. Once your plan is active and data roaming is on, your eSIM should connect to a local network shortly after you land at Sarajevo International Airport, so you can order a taxi or open maps right away.
Does the eSIM work at Mostar, Tuzla and Banja Luka airports too?
Yes. Coverage isn't tied to a specific airport, so the eSIM connects to available local networks whether you arrive in Sarajevo, Tuzla, Banja Luka or Mostar.
Can I use my Bosnia eSIM in neighbouring countries like Croatia or Serbia?
A country-specific Bosnia plan only works inside Bosnia and Herzegovina. If your trip covers Croatia, Serbia or Montenegro too, choose a regional Balkans or Europe plan instead, since Bosnia is not in the EU roam-like-home zone.
Is Bosnia included in EU roaming plans?
No. Bosnia and Herzegovina is not part of the EU, so EU 'roam like at home' rules and many Europe eSIM bundles do not include it. Confirm coverage before buying a regional plan for a Balkans trip.
What happens when I run out of data in Bosnia?
Your data simply stops until you top up. You can buy another HelloSIM plan or top up your existing one through your account, and connectivity resumes once the new allowance is active.
How do I top up my Bosnia eSIM?
Log in to your HelloSIM account, choose a top-up or new data bundle for Bosnia, and it applies to your existing eSIM without needing to install a new QR code in most cases.
My Bosnia eSIM shows no service, what should I do?
Check that the eSIM line is selected for data, data roaming is enabled for it, and Airplane mode is off. Toggling Airplane mode on and off, or restarting the phone, usually forces it to re-register on a local network.
My eSIM isn't registering on a Bosnian network, how do I fix it?
Try manually selecting a network under Settings by turning off automatic network selection and choosing BH Telecom, m:tel or HT Eronet. Also confirm the plan is activated and you're not deep in a mountain valley with no signal.
Why is my data slow in Bosnia even with signal?
Slow speeds often come from being on 3G in a rural area, network congestion, or the phone being locked to a weaker band. Try toggling Airplane mode, or manually pick a different local network to reconnect on 4G.
What is the emergency number in Bosnia and Herzegovina?
112 works as the general European emergency number in Bosnia. You can also dial 122 for police, 123 for fire and 124 for ambulance. Emergency calls work even without an active data plan or with signal from any network.
Can I get a refund on a Bosnia eSIM if my phone isn't compatible?
HelloSIM's refund policy generally covers unused eSIMs that haven't been installed or activated. Check compatibility before buying, and contact HelloSIM support promptly if there's an issue with an unactivated plan.
How long is a Bosnia eSIM data plan valid?
Validity depends on the plan you choose, commonly ranging from a few days to 30 days. Pick a validity window that matches your trip length so your data doesn't expire before you leave.
Can I use the eSIM for Google Maps and navigation while driving in Bosnia?
Yes, the eSIM gives you live data for Google Maps or Waze as you drive between Sarajevo, Mostar and the countryside. For remote mountain roads, download offline maps in advance in case signal drops.
Should I download offline maps before travelling in Bosnia?
Yes, it's a smart backup. Coverage is strong in cities but can weaken on mountain passes and in rural areas, so downloading offline Google Maps of your route keeps you navigating even without signal.
Can I install the Bosnia eSIM on more than one device?
No, each eSIM QR code can only be installed on a single device. If you want data on a second phone or tablet, you'll need a separate eSIM for it.
Will the eSIM keep working if I take a day trip to the coast at Neum?
Neum is Bosnia's short coastal strip and is inside the country, so a Bosnia eSIM works there. If you cross into Croatia along the coast, you'd be outside the plan's coverage and need a regional option.
Do I need to remove my physical SIM to use the eSIM in Bosnia?
No. The eSIM works alongside your physical SIM in dual-SIM phones. Keep your home SIM in place for calls, set the HelloSIM eSIM as your data line, and disable roaming on the home SIM.
Is using an eSIM cheaper than roaming with my home carrier in Bosnia?
For most travellers, yes. Because Bosnia is outside the EU, standard roaming from many carriers can be expensive, while a dedicated HelloSIM data plan gives you a predictable, usually lower price.
Can I share the connection with my travel companions in Bosnia?
Yes, by turning on your phone's hotspot you can share your eSIM data with companions' phones or laptops. Keep in mind everyone's usage comes out of your single data allowance.
What should I do with the eSIM after my trip to Bosnia ends?
Once your plan expires you can simply delete the eSIM from your phone's settings, or keep it installed in case you return and want to buy a new plan for the same profile later.
