You can verify this by navigating to Settings > Cellular (or Mobile Data) on your iPhone. If you see an option for 'Set up eSIM' or 'Add Cellular Plan' and there isn't a physical SIM card slot mentioned, your device likely supports eSIM. However, regional variations or carrier restrictions can sometimes affect availability, making it vital to check your specific device's specifications.

Checking Your iPhone's Network Lock Status

For an eSIM from a provider like Ubigi to function correctly, your iPhone must be unlocked from its original carrier. A locked phone restricts you to using only the SIM cards (physical or eSIM) from the carrier that sold you the device. To determine if your iPhone is unlocked, you can often check within the cellular settings. Go to Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If you see an option for 'Cellular Data Network' or similar, and there's no mention of carrier restrictions, it's a good indicator. Alternatively, insert a SIM card from a different carrier; if it works, your phone is unlocked. If it displays an 'Invalid SIM' or 'SIM Not Supported' message, it's likely locked. You will need to contact your original carrier to request an unlock if your device is not already free from carrier restrictions. This step is foundational, as an eSIM activation will fail if the phone remains locked.

Confirming both eSIM capability and network unlock status are non-negotiable prerequisites for a successful Ubigi eSIM activation.
