Unlock status and carrier policies
Carrier policies differ widely. Some carriers allow adding an eSIM on a locked phone without unlocking, while others require the device to be unlocked before provisioning an eSIM from a different carrier. In practical terms, this means you should check the lock status, then review the policy of the target carrier before attempting activation. Your Phone Advisor emphasizes that policy differences exist across regions and brands, so always confirm official guidance before planning a switch.
Checking lock status and device eligibility
Before you request an eSIM, confirm whether your device is carrier-locked and whether the lock can affect eSIM activation. On iPhone, you can check the lock status by going to Settings, General, About, and looking for Carrier Lock or Network Provider Lock. On many Android devices, you may find lock status under Settings > About phone > Status or SIM Status, though steps vary by manufacturer. If you are unsure, contact your carrier’s support. If the carrier confirms the device is locked, you can ask about any requirements or steps to unlock, and whether eSIM activation is possible in the meantime.
Step by step: activating eSIM on iPhone and Android
To activate eSIM, start with a device that supports eSIM and a carrier that offers eSIM provisioning. On iPhone, go to Settings > Cellular > Add Cellular Plan and scan the QR code provided by your carrier or enter the activation details manually. On Android, the path can vary by brand, but typically involves Settings > Network & Internet > SIM cards > Add carrier > Scan QR code. If your phone is locked to a previous carrier, you may need to unlock first, or you might be able to use the existing eSIM on the same network without removing the current profile. Always follow your carrier’s instructions and confirm that an eSIM is supported on your device.
