If you're concerned that the eSIM might activate earlier than expected, please turn off our network after you see "Activation failed." Once you arrive at your destination, switch to our network and then enable data roaming; it should generally work.
After Arrival: Turn off airplane mode, and activation should complete within a few minutes. If it doesn’t complete after a few minutes, please restart your device.
