I have apples visual voicemail service active. However recently I just started getting text messages with voicemail transcription as well however I do not have voicemail to text service active on my line. When I tap the phone number link in the text message with the transcription of the Voice Mail it takes me to a phone number that answers with "welcome to the SMS link service." That phone number is one digit different every time I get a text message with a voicemail transcription. What is this? And how do I get rid of it?
It seems to be worked out now. T-Mobile had to remove visual voicemail from my account and re-add it. It seems it may have been a hangup between android and iOS when changing Sim cards between the two phones and the different operating systems and how they handle Voice Mail.
How did you get them to address the issue?
I am experiencing the same thing, and they keep telling me to call Apple... but this isn't an Apple issue.
