However, if you have more Ampere A1 Compute instances provisioned than are available for an Always Free tenancy, all existing Ampere A1 instances are disabled and then deleted after 30 days, unless you upgrade to a paid account.

After your Free Trial expires, you'll continue to be able to use and manage your existing Always Free resources, and can create new Always Free resources according to tenancy limits. Resources identified as Always Free will not be reclaimed. (Note that reclaimed resources can’t be recovered-they are permanently deleted.) If you do not upgrade to paid by the end of the grace period, your Free Trial service instances and data will be deleted. Your resources will continue to exist for a few days, allowing you to upgrade your account and keep your resources before they're reclaimed by Oracle. You will no longer be able to create new paid resources, but your account will remain active.

When you've reached the end of your 30-day trial or used all your Free Trial credits (whichever comes first), you’ll be notified and will have a grace period of 30 days, starting from the expiration date, to upgrade to paid.
