Android eSIM Setup for a Balkan Road Trip
Install a Balkan eSIM on any Android phone: find the right menu whatever the skin, check the EID, and set roaming so the line survives every border.
Updated August 24, 2026
There is no single Android. The tap sequence differs between manufacturers, between skin versions, and sometimes between two phones sold under the same model name in different countries, so this guide gives the pattern rather than a script. Two things are constant: *#06# tells you whether the phone has eSIM hardware, and the search box at the top of Settings finds the eSIM screen faster than the menu tree. For a Galaxy or a Pixel, the Samsung and Pixel pages are more specific.
What does not vary is the reason for buying a regional plan. An EU contract’s roam-like-at-home allowance covers the EU members on this route and stops at the barrier when you leave them — the crossing into Serbia or Albania is where a normal contract quietly becomes expensive. The fallback most drivers use is a local SIM in each non-EU country: three or four shops in a single week. One eSIM that stays attached over every crossing on the plan is the point of it. Prices are on the pricing page, and the other device guides sit under guides.
The limit you must not misread: Türkiye is not part of this plan. The data stops at the Turkish border. No roaming setting, manual network choice or workaround carries it across, and a driver who arrives at Kapıkule assuming otherwise has been let down. The app sells a Türkiye plan separately — buy both if that is your route, and change which line carries data once you are through.
Everything after the install is about keeping one line working while the car keeps moving. Roaming on for the eSIM, roaming off for your own SIM, automatic network selection left alone until it visibly fails, and a few minutes’ patience at each border before you change any settings. Anything this guide does not cover is likely on the FAQ.
Installation steps
-
Step 1
Check for an EID before anything else
Open the dialler and type *#06#. Alongside the IMEI you are looking for an EID, a long number that only appears on phones with eSIM hardware. Manufacturers ship different variants of the same model in different regions, so the number on your own screen is the only answer worth trusting.
-
Step 2
Buy the plan in the Balkan eSIM app
Choose the plan that suits your route. After payment, the QR code and the manual activation details are saved under your order, so a failed first attempt is not a lost purchase.
-
Step 3
Do the install at home, on Wi-Fi
Downloading an eSIM profile needs internet, and you may not have any at the point where you finally want the line. Installing early is free in every sense: the plan begins when the line first connects inside the covered area, not when you buy it.
-
Step 4
Find the eSIM screen in Settings
Every manufacturer names this differently. The pattern is Settings, then Network & internet or Connections, then SIMs, SIM manager or Mobile network, with an option in there to add or download a SIM. Rather than hunting through menus, use the search box at the top of Settings and type eSIM. That finds it on almost every skin.
-
Step 5
Add the eSIM and scan the code
The button might read Add eSIM, Download a SIM instead, Scan carrier QR code or something close. Scan the code from a laptop or another phone. With only one screen, look for the manual entry option and copy the SM-DP+ address and activation code from your order — the result is the same line.
-
Step 6
Label it and keep it switched off for now
Name the line Balkan or Trip so you can tell it apart from your normal SIM at a glance, and leave calls and messages assigned to that normal SIM. Then disable the new line. Installed and switched off, it does nothing at all.
-
Step 7
Turn it on and make it the data SIM
When you are inside the covered area, go back to the SIM screen, enable the Balkan eSIM line, and set it as the SIM used for mobile data. Your own number stays where it is, on your own SIM.
-
Step 8
Roaming on for the eSIM, off for the home SIM
Find the data roaming switch — usually inside the settings for each line, sometimes under Mobile network — and turn it on for the Balkan eSIM. This plan works by using other operators' networks in each country, so the line cannot attach without it. Then check the same switch is off for your own SIM. On a dual-SIM phone these are separate settings and it is easy to change the wrong one, so open each line and look.
Troubleshooting
Is Türkiye covered by this plan?
No. Türkiye is not included and no setting on the phone changes that — the line stops carrying data at the Turkish border. If you are driving into or out of Türkiye, buy the separate Türkiye plan in the app as well and switch which SIM carries data after the crossing. Bosnia and Herzegovina, Kosovo, Romania and Slovenia are also outside this bundle.
My phone has no eSIM option anywhere in Settings.
Run *#06# first. No EID means no eSIM hardware, and nothing in Settings fixes that — you would need a physical SIM. If an EID is there but the option is missing, the phone is probably carrier-locked, which only the operator that sold it can undo, or the skin has buried the screen where the search box will find it faster than you will.
The QR code will not scan.
Increase the brightness on the screen showing the code, hold the phone roughly 20 to 30 cm back, and get the whole square in view without glare. If the camera still refuses, use manual entry and copy the SM-DP+ address and activation code from your order. A hand-entered profile is identical.
We have crossed a border and the data has not come back.
Give it a few minutes — the phone releases the old network and registers on a new one by itself, and at a busy crossing that takes a little while. If nothing changes, toggle Airplane mode off and on. If it still will not attach, turn off automatic network selection for that line, choose one of the networks the phone can see, and set it back to automatic once you are moving.
Does turning data roaming on cost me anything?
Not on the travel line. It is prepaid for use in the countries the plan covers and no home operator is metering it — the switch simply tells Android the line may use a network that is not its own. Your usual SIM is the opposite case: an EU allowance stops applying as soon as you leave the EU, which is why its roaming switch stays off.
Can passengers use my connection?
Yes. Tethering is included, so the phone carrying the eSIM can run a hotspot for the rest of the car. The plan is data-only — no phone number, no calls, no SMS — so keep your own SIM active for anything needing a number.
