What to do if Inbox doesn't work?
Check your spam folder and the address used during payment. If the eSIM is not issued within an hour, refund is automatic according to the official page. Otherwise, write to [email protected] with your order number.
Check that the phone is unlocked, connected to a normal Wi-Fi network, and has the Add an eSIM option. If the QR code was already used, check if the line is already present in settings.
Activate the Inbox eSIM line and its data roaming, select it for mobile data, disable roaming on the usual line, then restart the phone. Leave the APN on automatic mode unless otherwise indicated on the ticket.
Do not delete the eSIM. Activation before arrival may stay pending until connection to a network in the destination country. Upon arrival, activate data settings and restart the phone if necessary.
