My wife’s iPhone exhibited this strange error message and she could not use her voicemail button to check her voicemail messages.
The last thing I wanted to do was call Telus for assistance. And so I went searching online for a solution. I found it here — the most bizarre set of steps I have encountered in resolving a smartphone issue. But it worked for me.
- Bring up the phone app
- At the Keypad type *5005*86*xxxxxxxxxxx# where x represents the 11-digit voice mail number which in her case was the same as her cellphone number
- Tap Call — nothing will happen
- Clear the number off the screen by switching to Favorites and then returning to Keypad
- Press and hold the 1 key
In our case, it called voicemail and from there the voicemail button started working again.
Why? I have no idea.
