press 4 from T-Mobile voicemail main menu to reach the mailbox options. I can not understand the voice instructions under each of the mailbox options because English is not my mother language and I feel the voice oral instructions are too fast for me to listen to. I need read them.
Have you tried using the visual voicemail app.?
I can not find “T-Mobile Visual Voicemail” under “App Store” on my iPhone 6?
