MMS on 2G (OS3.0) with default SMS/MMS app

Gigamaster89 said:
Same problem as others, APN won't save.

EDIT - If you put it on Cell data at the top AND at the MMS spot, it works.

Here is something for those who can't get the data to save in the settings. A lot of people have had success with this method.

For people who require different APNs for their mobile data and their MMS, there may be a fix for you. I am on a Polish network which requires different APNs and I am able to send MMS and browse the internet. This is what I did:

1. Install the Cydia package "ActivateMMS2G" and reboot
2. Go to help.BenM.at on your iPhone
3. Go to the second Mobileconfigs link, the one that allows you to create a custom Mobileconfig
4. Enter your MMS APN (i.e. mms.plusgsm.pl) for both of the APN fields (Mobile Internet and Visual Voicemail) and enable tether. My network requires no username or password, if yours does, you may need to enter those as well.
5. Press generate, install it, press OK, then reboot RIGHT AWAY. Do not check the settings!!!
6. Go to settings > General and scroll down to profile. If it says 2 (or more) profiles, delete/uninstall the one(s) that are not called "help.benm.at" (i.e. delete all but the one you just installed). If it only says help.benm.at, skip to step 8.
7. After deleting the other profiles, go back to help.BenM.at and repeat steps 3-5. The first time you try to install it, it may fail or hang while installing (it did for me anyway) if this happens, press the home button, reopen Safari, then try again, it should work.
8. Once your iPhone has rebooted, go to Settings > General > Network > Cellular Data Network. Your MMS APN should be present in every APN field.
9. Fill in your MMSC and MMS Proxy. Once again, my network has no username or password, so I am not sure if you should add this here or during step 4... Experiment!!
10. Reboot your iPhone.
11. Open Messages and try to send an MMS. If it fails, check your settings are correct.
12. If it is successful, go back to Cellular Data Network and change your Cellular Data APN to the one appropriate for your network.
13. Test your data connection.
14. Test your MMS.

This fixed it for me. It seems that the MMS APN can only be the APN included in the Mobileconfig, whereas the data APN can be anything. Let me know how it goes.

I've followed the directions very closely (or so i think) as well as other methods that i've come across on other sites and have had no luck in getting my carrier settings to appear so that i can change the apn's or the ability to toggle mms on or off. I've downloaded "Activatemms2g" successfully with no luck as well as trying "APN Editing" but when i attempt to download i get two errors towards the end of the installation:
Error: File not found at path AllowEDGEEditing
Error: No key or keypath to set value​
I just jailbroke my phone for the first time today and have had success installing other apps such as SbSettings and Cycorder so i don't know what's up with my phone not allowing APN Editing to dl. I've also tried going to help.BenM.at to no avail.

And for reference i am using a 2g iphone with 3.0 on AT&T, so if anyone has even managed to get as far as editing apn's/getting the mms toggle in settings i greatly appreciate your help
 
The way enabled editing APN's is to copy the Carrier.plist from the Unknown Carrier bundle folder to the AT&T folder. Then you can set it up however you want.
 
Would it be possible for you to explain this step by step for me? I'm slightly confused on how to do this.
 
can send but cannot receive

i had a problem that i could only send but not receive. If anyone else i having this problem put a 1 in front of the number.

1) Login to your phone with a Secure Shell Client
2) Go to System/library/carrierbundles/unknown carrier
3) Copy the file "carrier.plist" to your pc
4) Go to System/library/carrierbundles/att_us.bundle and copy the file you just took from unknown and past it over the current file
 
i just had to reboot a few times and the MMS toggle appeared after following your directions. I know that people say it takes awhile to have an MMS send, but mine hangs up around 90ish % and then i get the red exclamation point for a failed message. I've read on other forums that its more than likely due to the wrong carrier settings being typed in. If anyone knows the correct carrier settings for at&t that work please let me know. Thanks a ton everyone, especially DanielNTX, between using macrumors and modmyi i managed to almost have it haha
 
i have the $19.99 and my apn is internet2.voicestream.com, what would be the mms apn setting?

wap.voicestream.com for both cell and mms worked for me.
 
Any idea on why this has worked for so many, but for a few of us we've been giving a black screen of death on reboot?

I would do it again step by step. It's worth it. Especially with the image quality fix the fixes the blurryness.

I'll do it again when i know why it happened in the first place haha.. my jailbroken phone was just starting to "feel" right too.. haha
 
Hey guys I am usually pretty good at modifying this stuff but when I install the program in Cydia I am not getting the Cellular Data tab in my Network settings at all. I've tried rebooting twice reinstalling and everything.

Anyone have any idea what is up with my phone?
 
Phone keeps freezing

Hey guys I have insatlled this activate mms2g twice and both times I had to restore my phone and reunlock it. It's getting a little fustrating. My phone won't get past the first reboot after you download it from cydia. Is there anything that I can do to get this to work or am I just S.O.L. on this?

I've had the same issue, it just black screens after the reboot.
Is there something I'm missing? perhaps something that needs to also be installed? I had very little installed, so i doubt there was a conflict caused by something i had installed, but maybe i was missing something?

You guys definitely have a 2g iphone? The activatemms2g doesn't work on the 3g.
