When I first got my iPhone, all I had to worry about was setting up the call number, and everything. Then, out of the blue, it started asking me for my voicemail password. I HAVE NO IDEA WHAT IT COULD BE!!! Has anyone else had this problem?
I did. I tried the last 4, the first 3, the whole, 10-digit #. No matter what I enter, it goes away, and then pops back up in about 10 seconds
The default password is 1234.
Then go to settings>phone>change voicemail password.
Ok you should restore your phone now.
After you restore your phone the default password to set up your visual voicemail will be 1234. I am 100% certain of this.
