I'm pretty sure that when I upgraded to iOS6, all the settings in Cellular Data Network was reset/deleted.
1. Settings -> General -> Cellular -> Cellular Data Network -> Check all fields.
2. All entries as shown in the link in my previous post probably has to be filled according to your own phone operator. Try visit their website, they should have a post on how to set up MMS/internet. That should also take care of problems with sending pictures via email as well.
By the way, use Google Translate if you need a translation of the Norwegian page. ;-)
There is definately MMS and internet settings on the iPhone, but not in Settings -> Messages where you will only find the toggle for MMS.
I'm sure you guys in the States also have a "Cellular Data"-field:
Choose Settings -> General -> Cellular (scroll down) -> Cellular Data Network
Here you will find the MMS settings.
In the link below, my phone operator is showing how the set up looks like for my iPhone incl. pictures:
The specific picture link taken from the same page:
I spent ALL day on the phone with tech's from Apple (2 diff ones)
1st TECH told me -
1:press "home key" & power for 15 seconds - until phone powers itself back-up; then let her; So we did this - IT DID NOT WORK! As I had already told her when I called, I tried it before I called.
2:Next step:Reset Network Settings - Followed her advice word for word. IT DID NOT WORK! As I had already told her when I called, I tried before I called.
3:LAST step: RESTORE (w/back-up) She advised that I should restore my iPhone 4. So I hung up, printed out the CASE ID and RESTORED my phone - THIS DID NOT WORK!!!!
Back at square 1~
During the conversation; she also stated that if this did not work, a Senior Advisor would be contacted when I called back and possibly determine if it was software or "hardware" issue.
When I called back I spoke to a gentleman named "M"(name with held) and he walked me through all the SAME steps she did - EXCEPT with him we RESTORED my phone 2x's - once with iCloud and then a total WIPE OUT!
AGAIN - they did NOT WORK! A Senior Advisor was contacted and brought into the conversation by the name of "M" (name with held) also. We spoke about the problem in GREAT DETAIL!
He stated that HE was UN-AWARE of the problem with the PICTURES not being able to be sent with text messages. I said, "are you kidding? Your Apple forum is BLOWING UP and has been since the update came out! Go look!" So he did as we were on the phone. He advised that he would be submitting an RTA letter (like this is going to do me[or anyone else] any good) to engineering and have them look into the "issue" it could take A WEEK!
I expressed my OVERWHELMING concern that this was something in a previous iOS that had been adressed but I was not sure which one it was, I was unfamiliar with older versions.
I am PERPLEXED! DISAPPOINTED!
Using the Norwegian page that Roberg_NORsuggested, I was able to fix the problem. If you are using Google Chryome as your web browser, ou have an option to transulate the page.
Settings-------> General--------> Cellular---------> Cellular Datta Network
This gets you to the apn page. i entered everything but the MMSC
(Mine is http://mms.msg.eng.t-mobile.com//mms/wapenc).
I left the MMS Max Message size area empty
The MMS UA Prof URL on my phone reads: http://www.apple.com/mms/uaprof.rdf
On the Cellular data page on my phone it reads as follows
MMS Proxy 126.96.36.199
MMS Max Message Size (BLANK)
MMS UA Prof URL http://www.apple.com/mms/uaprof.rdf
I then shut the phone off and turned it back on. I HOPE THIS HELPS
