A Serbia eSIM works on a compatible, unlocked iPhone when the profile is installed correctly and selected as the cellular-data line. The home SIM can remain active for its number, but its data roaming should stay off unless you intend to use the home carrier.
Apple supports eSIM on many iPhone models, but availability differs by model and sales region. Verify the exact model in Settings rather than relying only on the family name.
NoveSIM Serbia plans are data-only. We do not provide a Serbian number, conventional calls or SMS. Internet calling and messaging can use the travel-data line.
Quick answer: Open Settings → Mobile Service/Cellular → Add eSIM → Use QR Code. Label the new line, choose it under Cellular Data, disable Allow Cellular Data Switching and enable Data Roaming only for the Serbia eSIM after arrival.

Open Settings → General → About and record the model number. In the same area, check Carrier Lock or Network Provider Lock; the phone should indicate that no SIM restrictions apply.
Some iPhone variants sold in particular markets use different physical-SIM and eSIM configurations. Confirm the exact device against Apple’s current documentation.
Add the Serbia eSIM
- Connect the iPhone to stable WiFi.
- Open Settings and tap Mobile Service or Cellular.
- Tap Add eSIM.
- Select Use QR Code.
- Scan the supplied code and follow the prompts.
- Label the line Serbia Data.
If the QR code appears in a supported email or browser on a recent iOS version, the phone may offer an Add eSIM action. A second screen remains the clearest fallback. For installation timing, see the Serbia installation guide.
Choose Data, Voice and Messaging Lines
Select the home line as the default voice line if you need its number. Under Cellular Data, select Serbia Data and turn Allow Cellular Data Switching off.
This prevents iPhone from using the home plan when the Serbia connection weakens. Charges for calls, voicemail and SMS on the primary line remain subject to the home carrier.
Settings after Arrival
- Turn off Airplane Mode.
- Open the Serbia line and ensure Turn On This Line is enabled.
- Choose it under Cellular Data.
- Open its data options and enable Data Roaming.
- Leave Network Selection on Automatic.
- Wait several minutes, then test a map with WiFi off.
5G and Low Data Mode
Under Voice & Data, use 5G Auto when the phone and plan support it. Stable 4G is sufficient for normal travel tasks and does not indicate a faulty eSIM.
Low Data Mode can reduce background activity when the allowance is limited. It does not replace monitoring video, hotspot and cloud-backup use.
APN on iPhone
iPhone may hide APN fields when carrier configuration controls them. Do not force an edit when the plan works automatically. If manual NoveSIM entry is required and the menu is available, use data.esim without a username or password.
Incorrect APN settings can remove data connectivity. Follow the Serbia APN guide rather than entering a local operator’s value.
Troubleshoot without Removing the eSIM
- Confirm the Serbia line is on and selected for data.
- Enable Data Roaming on that line.
- Turn Cellular Data Switching off.
- Toggle Airplane Mode for 30 seconds.
- Restart the iPhone.
- Check plan status and Serbia coverage.
Do not delete the profile. If the line still fails, record the iPhone model, iOS version, network name and error before contacting support.

FAQ
Which iPhones support a Serbia eSIM?
Many recent iPhones support eSIM, but model and sales region matter. Verify the exact model and confirm that it is unlocked.
Can I keep my normal number active?
Yes, with Dual SIM. Keep the home line for its number and select the Serbia eSIM for cellular data.
Should Data Roaming be on?
Enable it for the Serbia travel eSIM. Keep it off for the home line unless you deliberately use the home roaming plan.
Why does iPhone show 4G instead of 5G?
Coverage, device compatibility, plan access or local conditions may select 4G. If data works, do not delete the eSIM.
Final Recommendation
For a Serbia eSIM on iPhone, confirm the exact model and unlock status before scanning the QR code.
Choose the travel eSIM for Cellular Data, disable data switching and enable roaming only on that line after arrival.
Keep the profile installed during troubleshooting. Correct Dual SIM selection is more often useful than reinstalling the eSIM.
