Google is testing out a change to Gmail that might make the service a little bit less useful for newcomers.

The company confirmed to Android Authority that it is testing a policy shift that would see new Gmail accounts get a mere 5GB of free cloud storage, down from the 15GB that's been guaranteed to Gmail accounts for years. This change wouldn't affect existing accounts that already have 15GB of free storage, but anyone who wants to make a new account would be limited, at least as long as they live in one of the regions where this is being tested.

According to Android Authority, the test is largely limited to African countries right now.

"We’re testing a new storage policy for new accounts created in select regions that will help us continue to provide a high-quality storage service to our users, while encouraging users to improve their account security and data recovery," Google said in a statement to Android Authority.

The good news is that there is a way around this. Users who want the free 15GB of storage can simply attach a phone number to their account, and the 5GB limit will be lifted. Obviously, there might be security concerns associated with doing such a thing, but a fix is a fix. And, as Google's statement said, attaching a phone number to an account can actually increase its security through two-factor authentication, among other reasons.

Of course, this is only a test, so it may not ever become a global policy. If you don't already have a Gmail account, now might be the time to make one. You can also change your Gmail username, another recent change to long-standing Google policy.
