FAQs

• Q.What is an eSIM?

  A.

  This service enables users to establish profile information on the SIM card integrated into their smartphones, facilitating Internet connectivity across different countries and regions. Unlike WiFi devices that require constant portability, smartphones equipped with this service offer a smarter solution for Internet access.
  Please note that this service is not available except SIM-free or SIM-unlocked eSIM compatible smartphones.

• Q.How do I know if my device supports eSIM?

  A.

  An EID is required to activate an eSIM.
  Open the Phone app and dial *#06#.
  Your device can use World-eSIM if the EID is displayed.

  Ensure that your device is also SIM-unlocked (SIM-free).
  You can verify these details with the retailer where you purchased your device.

• Q.When can I start communicating after purchase?

  A.

  You will receive the necessary eSIM setup information, including profile details, via email approximately 5 minutes after your purchase. The setup process typically takes around 5 minutes, and you will be able to use your eSIM immediately after the setup is complete.
  Please be aware that this service is exclusive to the country plan you have purchased and cannot be utilized in any other country plan.

• Q.When should I do the setup?

  A.

  A stable Internet connection is required for eSIM setup.
  Setup timing depends on the plan you purchased.
  For more details, please check the details of the purchased plan in My eSIM.

• Q.What happens if I run out of purchased data communications?

  A.

  Data transmission will be suspended or speed will be limited even within the purchased usage period.
  You can access My Page from the World eSIM app or website to recharge additional data capacity within your usage period.

• Q.Can I make voice calls?

  A.

  You can make voice calls if the plan is labeled "Phone Number-Included".
  Plans without a phone number are data-only, and you cannot make voice calls using a phone number.
  Additionally, depending on the country, "Phone Number-Included" plans may not be available.
  Please use internet calling features such as those available in LINE or Instagram, which are accessible through internet communication.
