  NOTE:
  - If a master account grants the OCR FullAccess permission to an IAM user, both the master account and the IAM user can subscribe to OCR services. IAM users without this permission cannot subscribe to OCR services on their own.
  - If a master account only grants the OCR ReadOnlyAccess permission or no permission at all to an IAM user, only the master account (or IAM users with the OCR FullAccess permission) can subscribe to OCR services for that IAM user.
  Alternatively, you can click Buy Package to subscribe to a service. The billing is on a package basis.

4. Once the service is successfully subscribed to, check that the status is Subscribed.

  NOTE:
  - OCR services are billed in pay-per-use mode by default. In this billing mode, you only need to pay for what you use. If you have purchased a package, see Billing for package deduction rules. Packages cannot be refunded once being purchased.
  - If you have not subscribed to an OCR service yet, an error message with error code "ModelArts.4204" will be displayed when you call the OCR API.
  - If you want to use data stored on OBS, you can authorize OCR to access OBS. You only need to configure the authorization once. For details, see Configuring Access Permissions of OBS.
