Many of you are aware of a thread in the Focus S section of this forum about someone with their Focus S getting VVM to work. However, it wasn't the most helpful thread to replicating it. I have since replicated this on a different device (the Focus Flash), so I wanted to post something here to let more people know.
Thanks to davezaff for the idea.

Here is how I did it on my Focus Flash. You will probably need a way to edit the APNs.

1. Update to 7740
2. Update to 8107
3. Insert sim card into an AT&T Android LTE phone (I used skyrocket)
4. Go to and switch plan to Data Pro 4g LTE plan. I had to call to switch since it wasn't working on the website.
5. Setup VVM on Android LTE phone (don't know if this is necessary, but this is what I did....make sure friend knows the VM password so they can re-add it when they put their sim card back in.
6.Insert sim card back into Windows Phone
7. Call Voicemail
8. Wait for VVM to show up on phone (mine showed up after calling voicemail).
9. If sync error, edit the APN as follows

APN settings (delete the internet_line APN)
Create a new APN

APN Name: pta
Profile Category: internet (always on)
APN: pta
Auth type: None
Proxy address:
Proxy domain:
Proxy port: 80

I now have working VVM on AT&T with my Samsung Focus Flash. My internet tethering still works (applied the Interop unlock + tethering hack from XDA). I have not tested MMS since I did this, but the MMS APN was untouched.

So they have tied vvm with their stupid data plans, how nice. So I can pay $20 for 300mb + vvm or I can pay $10 for unlimited data and traditional vm... ATT is so dumb.

For the normal person, it is pay $30 for 3GB of data with traditional VM or pay $30 for 3GB with VVM. The only difference is one plan has the word LTE at the end.

Does this work if you don't setup VVM on the android device first? I was thinking of just calling AT&T and asking to be switched to the 4G plan.

Get it working without an LTE device
OK, I got this to work on my Lumia 800. Furthermore, I didn't have an LTE device.

What I did have however, is an AT&T store that caters extensively to my place of work (a software company). They are really nice, understand unusual requests, and try everything to help.

I did the following:
1. Upgrade the OS as per the original post.
2. Call the nice AT&T store that I mentioned above. Asked them to put me on an LTE plan. (I was already on an enterprise plan, so I was moved to the same enterprise plan but the LTE version. Cost of my plan remained unchanged).

I explained that I was doing some app development, and planned to be swapping phones from time to time, some of which are LTE phones. (I also have a microsim adapter, so moving between phones that take microsim and regular sim is not an issue for me).
They asked if I'd like VVM provisioning. I said yes.
They told me that they would change my listed phone to a blank IMEI (basically change the IMEI listed on my account to a blank IMEI that's associated with an LTE phone for provisioning purposes). I don't know if this is something all stores would be willing to do.

3. In the APN settings, I changed my APN to pta. I did NONE of the other settings mentioned (proxy, proxy port, and everything else are BLANK).

Now I have Visual Voicemail on my Lumia 800!
