Visual voicemail is now enabled on the AT&T Lumia 950 XL dual-SIM for Windows Insiders on the Fast Ring. We were first tipped to the feature addition by a reader, and we were able to confirm that visual voicemail is indeed active on our own Lumia 950 XL (dual-SIM) running the latest Windows 10 Mobile Fast Ring build.

With visual voicemail, users will have access to a visual interface for interacting with and managing voicemails. It's a pretty big feature addition, so it's nice to see it make an appearance.

It is important to note that we've only confirmed visual voicemail's appearance on a dual-SIM Lumia 950 XL connected to AT&T's network. It's unclear if the feature is also available for the Lumia 950 or even on other networks for those running the latest Fast Ring Insider build for Windows 10 Mobile.

We should also caution that in our initial tests while we can setup visual voicemail and the Phone app does check for new messages we have yet to actually see a visual voicemail on our device. This is a known issue with the Fast Ring as detailed in the release notes:

"Visual Voicemail notification and delivery is not working in this build; causing devices to not receive any new visual voicemails. You can manually check your voicemail by calling your voicemail to listen to any new messages. You can call your voicemail within the Phone app by clicking "…" > Settings > "Change more settings for Phone" > "Call voicemail"; this will also leave the Voicemail call in your history to make checking voicemail easier."

Despite it not being fully functional hope springs eternal that this is the first step in enabling visual voicemail on the Lumia 950 XL and other dual-SIM Windows 10 Mobile devices.
