Bosnia eSIM activation means turning on an already installed travel profile and configuring it as the phone’s mobile-data line. Installation and activation are related, but they are not always the same event.
Read the purchased plan’s validity rule before switching it on. Some plans begin when they first connect to a supported network, while product-specific instructions determine the correct timing.
NoveSIM travel eSIMs are data-only. They do not provide a Bosnian number, conventional calls or SMS; internet calling and messaging apps use the data connection.
Quick answer: After arrival, enable the installed Bosnia travel eSIM, select it for mobile data, turn on data roaming for that line and disable automatic switching to the home SIM. Keep network selection automatic, disconnect Wi-Fi and test a webpage.

When the plan permits advance installation, add the eSIM over reliable Wi-Fi before departure. Give it a clear name such as “Bosnia Travel” and keep the QR code or manual details private. Do not scan a single-use code on another phone.
If the profile has not been added yet, follow the Bosnia eSIM installation guide. Confirm that the device is compatible and unlocked before starting.
Bosnia eSIM Activation after Arrival
- Open the phone’s SIM or Cellular settings.
- Turn on the installed Bosnia travel eSIM.
- Select it under Mobile Data or Cellular Data.
- Enable Data Roaming inside the travel eSIM settings.
- Disable automatic data switching to the primary SIM.
- Leave Network Selection on Automatic.
- Turn Wi-Fi off and test a normal webpage.
Registration may take several minutes after landing. Signal bars alone do not prove that data works, so test with Wi-Fi fully disconnected.
Keep the Home SIM under Control
A dual-SIM phone can often leave the usual number active for messages or calls. Keep mobile-data roaming off for that line and check the home provider’s voice and SMS charges. Bosnia and Herzegovina is not automatically covered by EU/EEA roaming rules.
The Bosnia roaming guide explains how to prevent the phone from silently returning to the primary SIM for data.
What to Do if Activation Does Not Complete
- Confirm the plan is valid and the eSIM line is enabled.
- Re-select the eSIM as the mobile-data line.
- Check Data Roaming on that profile.
- Toggle airplane mode once and wait.
- Restart the phone once.
- Try manual network selection only after automatic registration fails.
If the APN is missing or incorrect, NoveSIM uses data.esim. Do not replace a working automatic value and do not enter a Bosnian operator’s APN. The Bosnia mobile-data troubleshooting guide covers signal, registration and slow-data cases.
Do Not Delete the Installed Profile
Deleting an eSIM is not the equivalent of restarting it. A QR code may not support another download, leaving the phone without the profile needed for recovery. Keep it installed unless NoveSIM support specifically instructs removal.
When contacting support, include the order details, device model, screenshots of the eSIM settings and the exact error. Do not publish the QR code or activation credentials.
Confirm That the Correct Line Is Working
With Wi-Fi off, open a browser and a map. Check the mobile-data usage screen to see which SIM is transferring data. Only then enable background services or hotspot, if the plan and device support it.
Availability of networks, 4G, 5G, hotspot and speed depends on the plan, handset, location and local coverage.

FAQ
When should I activate a Bosnia travel eSIM?
Follow the purchased plan’s validity instructions. Many travellers install in advance and enable the line after arrival.
Why must Data Roaming be enabled?
The travel eSIM may connect through partner networks, so roaming normally needs to be enabled on that specific line.
What is the NoveSIM APN?
The APN is data.esim. Change it only if the field is available and the automatic value is missing or incorrect.
Should I reinstall an eSIM that will not activate?
No. Keep the profile installed and contact support after checking the line, roaming, network and plan status.
Final Recommendation
Install in advance when the product instructions allow it, but activate according to the plan’s validity terms.
After arrival, complete Bosnia eSIM activation by selecting it for data, enabling roaming on that line and testing with Wi-Fi off.
If activation is delayed, change one setting at a time and preserve the installed profile while support helps diagnose the problem.
