It looks like Google is going to make a very unpopular change to Gmail

Key Points:

• Google currently offers 15 GB of free storage for personal Gmail accounts, which can be expanded through Google One subscription plans ranging from 100 GB to 2 TB, with additional features like AI tools and perks such as Google Store discounts and extended Google Meet calls.
• Users can avoid paying for more storage by deleting emails, photos, and device backups, but some create multiple Gmail accounts to gain extra free storage, a practice Google aims to curb.
• Recent indications suggest Google may reduce free storage for new Gmail accounts without a phone number verification from 15 GB to 5 GB, as part of efforts to prevent spam and multiple account creation.
• Google updated its support documentation to state "up to 15 GB" of free storage, hinting at this potential change, and offers users the option to unlock full storage by verifying with a phone number during account creation.
• Additional Google One storage and features are accessible via the Google One website and apps available on iOS and Android, while users are encouraged to manage existing storage by deleting unnecessary content.
