I have the iPhone 7 Plus. Have had it since Saturday January 28, 2017.
I don't know that I have voicemails unless I manually check the VM tab in the Phone app. There is no badge on the VM tab, nor a notification in the drop down screen, nor the lock screen.
I originally had no issues, until I realized I had missed calls, but no notifications that I had voicemails. (standard nor visual)
I contacted chat once, called support a couple times. Visual Voicemail was provisioned for my line as well as my second line, also on an iPhone 7 Plus. The second line has had no issues with the message waiting indicator, badges, or banners/alerts.
T-Mobile had me return my phone to the store yesterday and exchange for the same model. Yet, the issue remains.
I contacted support again and was told to allow 2-24 hours for all the account changes to catch up, sync, and fall into place. I was told I'd be contacted again at 3PM today. That call never came.
I called support again today a few minutes ago and was told that I had no issue, that I was still getting my voicemails and that the only issue, if there was one, was that other than using an iPhone (?) that I was basically being petty about not receiving notice that I had voicemails waiting.
I was then told that it was a known issue affecting all iOS users and that T-Mobile had no ETA as to the rectification. Then I was told it only affected some users, after I mentioned my second line had no issues in this regard. Apparently, the issue has been known since January 12, 2017. Apparently no one at the store (manager included) nor any other rep at T-Mobile nor Apple (whom I chatted with 3 times about this issue) knew that this known issue was really an issue.
Anyone with any info about this Push-MIW notification issue?
