Voicemail not working no alert telling me I have voicemail how to fix iPhone

Hey, I've had the same problem; I don't have a solution but thought posting what I've done so far might help with collaboration and figuring out how to fix this.

Equipment: iphone 3gs, software 3.1.2.

I spoke with ATT this past week and the customer service rep made changes on the "back end" while I updated my software on the front end. So far, unfortunately, nothing has worked. Data connectivity seems to be working fine, but I'm unable to change my VM password from my phone - it gives me an error stating something similar to "voicemail is currently unavailable, try again later". Manually checking my mail by hitting the #1 key, however, works, and I can change my password that way. ATT is following up with me later today; I'll let you know if I come with a solution! I'd appreciate it if you did the same!

Peace,
DB

I had this problem and while going through my phone settings i noticed i had an unsigned carrier file. i removed the carrier file, reset the phone and voicemail came back

Hey all, I had the same problem and found out that it was caused by the tethering hack profile I installed from Benm. You need to remove this profile before it will work. I actually removed it, but it still wasn't working so I re-installed and removed it again. That was finally the trick. I restarted my phone and my voicemails returned!

Remove the profile from Settings--general--profiles

Hope this helps!
