Using a Slovakia eSIM on iPhone is mainly a matter of compatibility, correct installation timing and choosing the right line for mobile data. The profile can appear installed while the phone still sends data through the home SIM, so the line settings deserve as much attention as the QR code.
Menu names vary slightly by iOS version and region. Confirm the exact iPhone model supports eSIM and is carrier-unlocked before purchasing a plan.
NoveSIM travel eSIMs provide mobile data. We do not provide a Slovak number or conventional calls and SMS, but internet-based apps can use the eSIM connection.
Quick answer: On a compatible unlocked iPhone, add the plan through Settings > Cellular/Mobile Data > Add eSIM. Label it Slovakia, select it for Cellular Data after arrival, apply the plan’s Data Roaming instruction and turn off Cellular Data Switching if you want to prevent fallback to the home line.

Open Settings > General > About and record the model and carrier-lock status. The phone should show no SIM restrictions or the equivalent unlocked status. eSIM availability can vary by model and market, so do not rely only on the family name.
Install over stable Wi-Fi
Keep the QR code available on another screen or use the provider’s supported manual method. In Settings, open Cellular or Mobile Data, choose Add eSIM and follow the prompts. Do not scan repeatedly if the first attempt pauses; confirm whether the plan already appears in the SIM list.
Installation and activation are not always the same event. Read what starts plan validity before installing days in advance. The general Slovakia eSIM installation guide explains the preparation steps.
Label the lines clearly
Name the new line “Slovakia” or “NoveSIM.” Keep the home line’s existing label. Clear names prevent the wrong line from being selected later and make screenshots easier to understand if support is needed.
Select the eSIM for mobile data
After arrival, open Cellular/Mobile Data and select the Slovakia line for Cellular Data. Apply Data Roaming to that line when the plan instructions require it. Travel eSIMs often connect through partner networks, so roaming may need to be enabled even though the plan itself covers Slovakia.
Turn off Allow Cellular Data Switching during the initial test. Otherwise, iPhone may use the home line when it considers that connection stronger, potentially creating unexpected roaming charges.
Keep the normal number only with understood costs
Dual SIM allows the home line to remain available for calls and messages while the eSIM carries data. Incoming and outgoing services on the home line remain subject to its carrier’s roaming terms. Data-only eSIM service does not make those conventional calls free.
Test before leaving reliable Wi-Fi
Turn Wi-Fi off and load two websites. If data fails, verify the selected line, roaming setting and current plan validity. Where manual APN entry is required for NoveSIM, use data.esim exactly. Toggle airplane mode briefly and restart once before considering manual network selection.
Do not delete the profile as a routine fix. Use the ordered checks in Slovakia mobile-data troubleshooting or contact NoveSIM support.

FAQ
Where do I add a Slovakia eSIM on iPhone?
Open Settings, then Cellular or Mobile Data, and choose Add eSIM. The wording can vary by iOS version and region.
Can I keep my normal SIM active?
Yes, on a supported dual-SIM iPhone. Select the Slovakia eSIM for data and check the home carrier’s call and SMS roaming charges.
Why is iPhone using my home SIM for data?
The home line may still be selected or Cellular Data Switching may be enabled. Choose the Slovakia line and disable switching during testing.
Should I delete an eSIM that does not connect?
No. Keep it installed and check data-line, roaming, APN and network settings. Delete it only when NoveSIM support explicitly instructs you.
Final Recommendation
Verify the exact iPhone and unlock status, install over stable Wi-Fi, label the plan and deliberately select it for data. Control Cellular Data Switching and preserve the eSIM profile while troubleshooting.
