Voicemail Notification Stuck I'm on T-Mobile, running Android 4.1.2 on Samsung Galaxy S2.

I have had this voicemail notification stuck on my home screen for the past two days. I can't swipe it off the notification screen (can't dismiss it), and when I check my voicemails it says I have none, so I'm unsure why it's still there.

I've tried multiple times reaching my voicemail inbox, to see if that would correct it... and I've reset my phone a couple times as well and still no luck.

Anyone else having this issue, or have any idea how to get rid of it (aside from completely resetting the phone, or calling T-Mobile and having them reset it)?

Long-press on the notification and you should get a little "app info" box.  Hit that, then hit "force stop".  If the app info box doesn't appear, go into Settings -> Application Manager -> All, find the Phone app, and force stop it.  That should send the notification packing.

If it comes back, the problem is T-Mobile sending out erroneous "You have voicemail" announcements and you'll have to talk to them about it.
