I think someone else accessed my account

Change your email password to a strong, unique one; enable two-factor authentication; review recent sign-in activity and sign out sessions you don't recognise; and check for forwarding rules attackers sometimes set up.

Review recent transactions in Billing & orders, recent eSIMs, and active sessions — sign out anything you don't recognise.

Tell us what you noticed and that you've secured your email. We can reverse unauthorised purchases (if unused), lock the account while we investigate, help you change to an uncompromised email, and provide an activity report. The single most effective defence is two-factor authentication on your email.
