Description

9esim offers a revolutionary approach to mobile connectivity by converting non-eSIM-compatible devices into compatible ones via a specialized SIM card and a USB reader. Store up to 50 eSIM profiles on a single card, download as many times as needed, and switch freely between networks. Ideal for digital nomads and travelers seeking maximum flexibility with unlimited downloads, 24/7 technical support, and an open-source architecture.

How it works

Order the 9esim kit including the specialized SIM card and compatible USB reader on the official website or authorized resellers.

Install the 9esim app from Google Play Store on your compatible Android device. Create an account or log in with your credentials.

In the app, browse available eSIM profiles for your preferred destination or region. Profiles are offered by various provider partners integrated into the platform.

Select the desired profile, pay using available payment methods, then download the profile code from your device.

Connect the USB reader to your computer (Mac, Windows, Linux), insert the 9esim card into the reader, then use the app to write the eSIM profile onto the card.

Remove the card from the reader and insert it into your Android phone's SIM slot. Restart the device to activate the new setup.

Go to your device's network settings, select the newly activated carrier, and make sure data roaming is enabled to start using connectivity.

⚠️ If it fails

✅ Check that the USB reader is properly connected to your computer, drivers are installed if necessary, and the card is correctly inserted in the reader. Refer to the documentation or contact technical support.

✅ Verify the profile was correctly written to the card by retrying the write operation. Ensure your phone supports the selected carrier's network and that roaming is enabled in settings.

✅ Check your internet connection, that you are logged into the correct 9esim account, and that the profile is available for your region. Try closing and reopening the app.
