Updated carrier file, 3.0 and visual voicemail fix

[shutter13]

I have seen a couple of people talk about losing their visual voicemail after adding the custom ipcc file to get mms and tethering on 3.0. My Visual Voicemail works on 3.0, but I would get the messages pretty slow. I just saw this on another forum and tried it, tested my visual voicemail and it came through very quickly. The slowness may have been an AT&T thing, maybe not, either way if yours doesn't work at all, there is no harm in trying this.

In Settings>General>Network>Cellular Data Network

Under voicemail...it it says wap.cingular change it to acds.voicemail and restart your phone.



You can always put it back to wap.cingular if it doesn't work.

Where were you last night when I spent 2 hours on the phone with ATT while they tried to trouble shoot and had no clue what they were doing. My voicemails were coming in 5-10 mins later or sometimes not at all. This little update in my settings and now I get my voicemail within 30 secs. Awesome.... thx!

Thanks! got my VM back! Any way you can walk me through the proper settings for MMS? I get the camera icon and can take a pic, but it fails to send??? I have the family unlimited texting plan too with non-iPhones that can send MMS.

The only settings I have marked for mms is the APN which is wap.cingular

It just shows you how much people who work in customer service really know about their jobs. Tech Support is a joke at many companies, even my own which we outsource. It's sad when you have to tell the Tech Support how to resolve the issue because they have the authorization and you don't!

shutter13 is extremely helpful to everyone on these forums and I think it's only right that whoever this thread has helped, please thank him.

I talked to a buddy of mine that used to be an att tech and is now an iphone developer and he told me how to do it, but its a PITA!! so, ill just play with tethering for now. but thanks again for the VM fix!

gotzaiPhone, here's what I had to do to make MMS work.

I have an unlocked Nokia E71, but my understanding is that ANY GSM phone will do, as long as it works on AT&T. You can buy a cheap Nokia pay-as-you-go phone for about $10 that will work. You need to pull the SIM card from your iPhone and plug it into the non-iPhone. Wait some time, make a couple test phone calls to ensure it's working.

AT&T knows what phone you're using (model wise) and will allow or block certain services appropriately (such as MMS messaging). The hacked carrier profile which enables tethering and MMS also disables the model reporting agent, so the iPhone no longer updates AT&T as to what model of phone it is.

The idea is that by using the non-iPhone, AT&T will update what it thinks you are using to be a non-iPhone. At that point, you can then plug the SIM back into the iPhone and your MMS messages will go through. How do you know what that point in time is? Since my non-iPhone supports MMS as well, I kept trying to send an MMS until it went through. That's when you know.

And now my iPhone tethers, does MMS, and my Visual Voicemail works.

Thanks for the VVM tip!

So the fix for visual voicemail worked well -- but when I went back to turn the tethering on, after I switched it on, it went back to the "Network" page and the tethering option was gone.

Any fix for that? Am I doing something out of order?
