Device not supported
Your phone needs to support eSIM. Most phones released since 2018 do, but it’s worth double-checking. See our device compatibility guide.Phone is carrier-locked
If your phone was purchased on a carrier plan, it may still be locked. Contact your carrier to check and request an unlock. Locked phones cannot use third-party eSIMs like Roamly.No internet connection
You need Wi-Fi to download the eSIM profile. Make sure you’re connected to a stable Wi-Fi network before trying to install.eSIM already installed on another device
Once an eSIM is installed on a device, it’s locked to that device. If you’ve already installed it on another phone, it cannot be installed again on a different one.Things to try
- Check your Wi-Fi — Make sure you have a stable Wi-Fi connection.
- Restart your phone — Turn it off and on again, then try the installation.
- Update your software — Make sure your phone is running the latest iOS or Android version.
- Try the QR code method — On your eSIM detail page, use the QR code option instead of the direct install button. This can sometimes resolve issues with the direct install flow.
