Skype is celebrating the tenth anniversary of its free video calling feature with the addition of mobile group video calling for all major smartphone platforms, the company announced in a blog post today. It's been six years since Skype enabled mobile one-to-one video calling, and now the Microsoft-owned messaging app is expanding the feature to multi-person calls on iOS, Android, and Windows 10 Mobile. The company says the feature should be available in "the coming weeks," but you can pre-register on the company's dedicated tenth anniversary website to try out an early version of it.

Skype isn't the first messaging app to add mobile group video calling; Google's Hangouts has had the feature for quite some time and supports up to 10 people on the same video call. Skype is also holding back on how many people will be able to participate in the same mobile video call. The service lets up to 25 people share a group call on desktop and 10 people share a video call, so we'll see if it's able to replicate that feat on the smartphone.
