Order and payment records for seven years, because tax and dispute rules require it. Support messages for two years. Technical logs for up to 90 days.
An account you delete is removed within 30 days at the latest — the sign-in goes immediately and ordinary personal data within a week. The records above stay, without your name or email attached.
eSIMs you have already installed are unaffected by any of this and keep working until their plans end.
