How to check if your phone supports 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.
How to check your data usage?

For iPhone Users: Before activating your eSIM, go to Settings > Cellular. Scroll to the bottom and tap "Reset Statistics." You can then monitor your usage under "Current Period" in the "Cellular Data" section.

For Android Users: You can typically view your daily or total data usage under the "Network & Internet" or "Data Usage" section within your phone's Settings.

How to choose the right data plan?

• Light Users: For messaging and basic web browsing. 1GB per day is typically sufficient.

• Active Users: For navigation (Google Maps) and uploading photos to social media. We recommend 2GB per day.

• Heavy Users: For video streaming, remote work, or high-volume data needs. We suggest 3GB+ per day or an Unlimited Plan.

What can I still do at 128kbps speed?

When your speed is limited to 128kbps, you can still send and receive text-based emails and messages (such as text on LINE or WhatsApp). However, browsing websites or using social media will be significantly slower, and loading content will require more time.
