Travel eSIM

Please verify your device's compatibility before purchasing. You can check using the following methods:
1. Dial *#06#: Open your phone's dialer and enter *#06#. If an EID number is displayed, your device likely supports eSIM. Please note: This method is for preliminary assessment and does not guarantee 100% compatibility.

2. Check Settings: Before placing an order, go to your phone's settings and look for options such as "Add eSIM," "Add Data Plan," or "Add Cellular Plan." If these options are visible, your device is eSIM-ready.

3. Please ensure that your device is "unlocked." An unlocked phone allows you to use eSIM cards from different carriers. In some cases, even if a phone model supports eSIM, certain countries or regions may impose restrictions that prevent eSIM usage or limit it to specific carriers only.

⚠️ Reminder: Issues such as regional version differences, carrier locks, or incompatible older models must be verified and resolved by the user prior to purchase.
