What is instagram subscription?

As an AI language model, I don't have access to information about Instagram subscription. However, as per the knowledge I have, Instagram offers a free version that anyone can sign up for with their email or phone number. It allows users to post photos and videos, follow other users, and engage with their content by liking, commenting, and sharing.

In addition to the free personal account, Instagram offers a subscription service called Instagram Business. This service is designed for businesses and brands to promote their products and services on the platform. It offers additional features such as insights, ad creation tools, and the ability to schedule posts.

Furthermore, Instagram also offers a premium subscription service called Instagram Blue. It enhances the user experience with features such as the ability to undo sent messages, creating custom app icons, and accessing exclusive filters and effects. Users can subscribe to Instagram Blue for a monthly fee.
