AT&T Activates MMS Functionality for U.S. iPhone Users

[pmhacker]

I have a 3G and an MS Exchange account for work email.

So, I guess I get to either have MMS and no work email, or work email and no MMS.

3.1 doesn't break exchange inherently. Our exchange server supports hundreds of iphone connections with no problems. We all use 3.1.

[patrickvanzandt]

I'm on a business account and my iphone nor my wife's iphone shows a camera after we update the carrier settings and restart our phones. I was going to restore until I read your post, so now I'll just contact att instead and see if they need to do anything on their end. Hopefully it will all work out! Thanks

If the camera iPhone is not showing, it's a iPhone software issue; AT&T will not be able to help you.

Where AT&T could help is if the icon is showing, but you get the red "!" when you try to send messages.

Possible solution: does the MMS On/Off switch show up in Settings > Messages? If yes, it it turned on?

If that is not there, you probably did not apply the carrier settings update correctly. Check Settings > General > About. What is the version number after "AT&T" in the "Carrier" field?

[Tomple]

I Love MMs!!!!

[ZipZap]

Folks after you install the carrier file reboot your phone.

Then shut off WIFI and 3G.

Send and MMS on Edge.

Then turn on 3G.

Send MMS

This worked for me a couple of weeks ago with carrier 5.1

[alsaleem]

So heres my story...

I upgraded from an iPhone 2g to an iPhone 3GS when the 3GS came out, I had an issue with my phone and sent it back to get a new one and during this time reactivated my 2g. On my ATT bill I paid the first month at my new iPhone 3gs rate, but from then on my billing went back to what it was with my old iPhone(not complaining). Basically what it comes down to is i would love to be able to use MMS, but I do not want to increases my bill just for MMS. I've tried sending the messages on 3g, edge, and wifi and just get the red !. If anyone has any advice I would greatly appreciate it.

[PinkyMacGodess]

I got the update yesterday but it didn't say to restart until the text message I got a half hour ago. The camera button is there now... Yippee...

[happy2000hk]

I did the carrier settings hack on a 3G iPhone running 3.0.

I can send and receive MMS to other iPhones, but when I send MMS to my parent's Nokia and Samsung phones, they're phones say it can't open the multimedia file. What's going on here???

[Smileyboy]

Carrier file says 5.5, I'm on 3.1 FW, I tried using edge, 3G, rebooted the phone, restarted the phone, restarted the network settings, called at&t 5x.... I'm out of ideas..... Anyone?

All you have to do is dl the ippc file found somewhere within this thread and then go through the motions of option left click to import, find where you save the file and add it, then reboot. The full directions are on page 11 of this thread and the ippc file is a few pages back.I hope this helps

[alhedges]

Updated and installed MMS yesterday on my 3G non-JB 3.1 phone with no problem. Yesterday I noticed a slight slowdown with some MMS's (~30 secs.), but everything is going in <10 secs today.

The biggest surprise to me is how useful I am finding MMS. I really wanted it because a few people still send me pictures by MMS dealing with those pictures is famously horrible. Sending pix to them is less of an issue, as I can use the e-mail workaround for non-iPhones. (This would be an issue if I didn't know what carrier they had, of course.) However, I find that I'm also using MMSs for people with iPhones...just as it's often easier to text than to e-mail, it's often easier to MMS a picture than to e-mail one.

Which I suppose makes sense, but I had forgotten how convenient MMS can be.

Shhh... you found the loophole that allows you to use a 3G/3GS on an original iPhone Data + Text plan. I'm in the same situation.

AT&T will not enable MMS on the original iPhone Data + Text plan, so unless you want to switch over to a new 3G/3GS plan and pay more per month, you'll have to live without MMS.

Now quit talking about Fight Club.

Nope. iMacoo7, that's not going to work for those of us who have a 3G/3GS on an original iPhone Data + Text plan. Thanks for trying.

I was using my 3GS on a 2G data plan as well since the 3GS came out. I was thinking it wasn't going to be worth it to pay $15 more a month just to send MMS. Yesterday came and the MMS update was released. I called AT&T and told them I was using my 3G on the 2G plan all these months and now wanted to get the 3G plan so I could send MMS.

She changed it, asked me if I paid full price for my 3G, I said yes. She changed my plan, sent me a test MMS and I also upgraded to unlimited SMS. Not regretting it one bit. It's been fun having MMS and my friends are having alot of fun with it too. Must have sent over a 100 yesterday.

Oh and my upgrade eligibility date didn't change since I paid "full" price for the iPhone. :D

[TXbug]

I can send MMS messages, photos included. But, others get network errors when they try to send MMS messages to me.

[rtdunham]

..just as it's often easier to text than to e-mail, it's often easier to MMS a picture than to e-mail one....

does an MMS photo arrive at the same resolution as an emailed photo?

UPDATE: Maybe i can answer this one myself. I did a test. I MMSd myself a photo, then emailed it from my phone to myself and opened it on my laptop. I emailed a second pic from my iphone w/o involving SMS to myself and opened it on the laptop. Lastly, using my iPhone i emailed myself a picture from my photo library, one taken by a higher-res camera and sync'd to the phone, and opened it on the laptop.

All three were received on my laptop at the same approximate resolution (600x800 minus a few pixels in one dimension on the photo from the library, which I had cropped).

Conclusion: Seems to me you can get a person a photo at the same res either by emailing it or by MMSg it. Does anyone see any flaw in that logic? Or maybe the rest of you knew that all along! :)

[RoadconeTuning]

so my mms was working fine yesterday after i updated to carrier 5.5 thru itunes, all legit 3.1 and no funky hacks.... last night while i was up in charlotte i love my ability to MMS out of no where about 10 minutes before i got the official "your account is able to mms now" now text. i cant seem to force it to work now... what was odd was it worked fine with 5.2 and 5.5 no problem then all of a sudden stopped working, i cant even send to myself anymore when i had successfully sent to Verizon phones as well as AT&T

[redraidermacman]

my mms isnt working, called att and they said it was a network issue in my area (dallas/ft. worth) but they said it would be fixed by 8:30pm, it is now 1:30 on saturday and it is still not working.....dont know if that helps anybody or explains anything, but that is my experience....

[VSMacOne]

It seems like it's being very spotty during the day. Last night I had no trouble sending and receiving MMS but today (just like yesterday afternoon) it's stuck on 90% and won't go. I guess they're still working on it...

[brooke1lyn]

I downloaded the carrier settings update and I have checked that mms is on. I've tried edge, rebooting and all the other suggestions in this thread. When I send a mms I get the red !. When I recieve a mms i still get the message from att telling me to viewmymessage(dot)com. Any ideas?

[hh83917]

Folks after you install the carrier file reboot your phone.

Then shut off WIFI and 3G.

Send and MMS on Edge.

Then turn on 3G.

Send MMS

This worked for me a couple of weeks ago with carrier 5.1

I can confirm that this method worked. I was going to post about this but I guess ZipZap covered it first.

Also, when you turn off 3G and your phone still said 3G, simply restart the phone and it should be on Edge on the top. Then send a MMS with edge. Once it went through, go to the preferences and turn on 3G. Send a mms again and it should work.

[knome]

Figured out what the problem was with my mms. Apparently when i did this:

http://forums.macrumors.com/showthread.php?t=510352&highlight=1500+text+messages+8.99

It made it so mms could not be enabled on my account because it was a text only plan. So i had to change my message plan over to an iphone specific plan.

[greatdecay]

Updated my carrier settings to 5.5 yesterday, reset my iphone & saw the new camera icon. Been trying to send MMS for the past 24 hours, but it always ends with the red icon of mms death. Have hard reset my phone (several times), reset my network settings, used the 'settings' screen to reset all settings, tried the edge/send mms/switch to 3G trick that people here have mentioned, but still all attempts to send an MMS end with the progress bar stuck at 90%, followed by the red icon of mms death.

Starting to get a little irate about this all.

Anybody else have any tricks up their sleeves, or should I just chalk this up to inferior AT&T network infrastructure in San Francisco?

:/

Mine did the same thing, it took about 3 tries and I don't know if the reciprocate even received it. It's just the network...keep trying.
I have no problems with receiving them, its getting them out.

[iMaconApple]

sending video mms by 3GS quality sucks..email is way better and clear..

[Rozee]

Just made the download for MMS it works great!

MacBook Pro 4G
Iphone 3G
Airport Express

[TeamMojo]

BS that they don't support the original iPhone. Facebook and using email both work fine with the camera and Edge. Even the cheapest POS flip phone from 5 years ago with a camera and Edge supported MMS. I understand the marketing move to get people to buy new phones. But that should be based on new features such as speed, better camera, GPS, etc. and not prohibiting the use of existing features in the 2G iPhone.

[Jethrotoe]

If you do not want to update, but still want MMS, you can get the carrier file which a few users have posted downloads for, and install it. To do this, download th ipcc file, plug in your iPhone to iTunes, go to the iPhone and hold Option key (SHIFT on a PC) and click "Update". You should now be able to browse to where you downloaded the carrier file. Reboot your phone, and you are all set. Hope this helps some of you.

I got the ipcc file alright but when I use SHIFT (I'm doing this on a PC not my Macbook) and click update, iTunes only looks for a ipsw file. I cannot see the ipcc file I put on my desktop in the directory and there is no option to see it in the file type dropdown. Am I doing something wrong? I have a 3G, 3.0 (for tethering) not JB.

[xIGmanIx]

thats why it just works, because they don't support jack except their newest hardware. Silly Mojo, didn't you know that only the newest hardware from apple can support MMS :rolleyes:

I can send MMS messages to friends on AT&T, but for whatever reason MMS messages don’t make it to my Verizon (previously Alltel) friends. :mad:

[Mr. Gates]

I got a $20 that says Apple will not shame themselves by using this feature in a T.V. commercial as a selling point.
The rest of the world would say" WTF ? You mean this is some new innovation?!?!":confused:

[bowlerman625]

ABOUT EFING TIME!!!! :mad:

Soooo tethering? :rolleyes:


Wait until we hear officially what tethering will cost us when it becomes available. Then the REAL whining will begin!

[adiazrael]

Ok, I've done the carrier update and restarted the phone. The camera logo is there but the pictures will not go through. I goes about 80% and it says "sending..." but it never goes and the red button shows up! I don't know what is wrong with this??!?!? What is the solution??? Is this a problem with software or AT&T issue?????:confused::confused::confused:

[Sayewhat]

Your solution is to sit around and wait for AT&T to unscrew them self. Its been hit or miss, with man more misses. Its been a few years since the Iphone has been out without MMS, whats another week or so even if AT&T broke their promise on the date?

[andy721]

I don't think the majority Apple will put a mms feature in their commercials more likely AT&T will.

[andy721]

3.1 is jailbroken on the iPhone 3G, but not the 3G[S].

Yeah I meant 3GS sense I have it listed in my Signature.

[greatdecay]

still not working for me here... starting to wonder if it has something to do with the fact that I originally had a first-gen iPhone before replacing it with a 3G in march...

harumph.

[Full of Win]

I got MMS now, where's tethering?


I just used it, its called NetShare, perhaps you should go to the App store and download it.

Finally broke down & gave AT&T customer support a call... on the phone with them now.... they've tried taking off/readding my texting plan, turning off my phone & reregistering it with the switch, all no dice so far... I think I may have them baffled....

Will update y'all as I find out more...

[MatthewStorm]

On a JB 3Gs. updated the carrier file. Took about 14 seconds to send a picture MMS in NYC.

Okay... update... just got off the phone with AT&T... the first customer support person tried the previously mentioned fixes, they didn't work, and they forwarded me on directly to tech support. I talked with a really helpful guy who just reconfirmed all that we'd done... and we found the culprit. if you hit #*06# on your keypad, it gives you some sort of internal AT&T routing ID (forgive me for my ignorance...) anyhoo, that number didn't match up with the number that AT&T had in their system... the number in AT&T's system was that of a 2G iPhone. Like I was guessing before, I'm pretty sure this is because I first opened my AT&T account with a first gen (2G) iPhone, and then in March upgraded to the 3G. I guess the AT&T system never updated properly...

Anyway, the tech guy escalated my case to the west region tech office, and I'm supposed to get a call back/resolution by the 30th at the latest. (although he said that 24-48 hours was more likely) This isn't an isolated case, as he also mentioned that he'd handled 12 of the same problems in the past 4 hours...

So, in summary, if you already have MMS working fantastic... If not, and you're getting the 90% and then failure thing, give AT&T a call & best of luck...

[slippery-pete]

Shocked, but it is working like a charm for me. I thought for sure At&T would screw this up

[solideliquid]

For those folks with a 3G or 3GS with the problem of AT&T never updating the account when their plan was updated from a 2G iPhone, how are these people using 3G internet on the device?

AT&T doesn't differentiate EDGE from 3G when it comes to data.
It's just data.

The data plan on a 1st gen iPhone is just that, a "data" plan, not an EDGE data plan. Same thing with the 3G and 3GS, it's a "data" plan, not a 3G data plan.

[Smileyboy]

I had to do a a Restore and a Fresh install. Basically setting up my phone as new and my MMS has been running great for the last 2 days.

For real! Our only hope and big plus that we have is, all us iPhone users actually carry a lot of weight when it comes to making our voices heard and AT&T being forced to listen and consider!

#*06# resulted in "Error performing request Unknown Error"

[MauiBoy]

Just FYI: I tried using the IPCC file that was posted here, and it caused my phone not to connect to AT&T's network here in north Texas. I confirmed that "AT&T 5.5" was the Carrier version, after a very lengthy restart time (~2 minutes). However, I just got "No service" at the top of the phone. Luckily, I still had my previous 5.0 IPCC file and was able to repeat the steps to put 5.0 back on there. Now, I have a connection to AT&T once again.

I've gotten the text message announcement from AT&T about MMS, but I still have yet to get prompted in iTunes for the new carrier settings file (after 3 days since the original text message).

Oh well, it's not like I'd use the send MMS feature anyway, when I have MobileMe email on the phone. Would be nice to receive the messages from friends, though, instead of going to the stupid AT&T website to retrieve it with a password. :rolleyes:

[CylonGlitch]

#*06# resulted in "Error performing request Unknown Error"

Ditto. Same thing on my end. I am going to wait 3 more days (that's all I have left of work) and then with the free time, reset the phone to defaults and start over. Since work is paying for my phone, I need to get a new account setup to transfer it back to me. So, I guess, from there I'll start fresh as well.

I hope all goes smoothly.. I really wish it wasn't AT&T but they have been "OK" so far.

Verizon maybe filtering MMS that comes from AT&T.

at&t 6.0 fw 3.01 jb-- after getting the red exclamation point for failure to send for a day and a half I found a useful tip to reset all settings and now i'm able to send and receive mms with no problems :D

[NightStorm]

Attempted my first MMS photo send over my lunch break this morning to someone on Verizon, received word back a minute later that they received it. I guess I'm a happy camper. :)

[rhynoh]

I just spoke with ATT Tech Support. He said there was an issue with my phone not registering correctly on their network. He had me go into Settings > General > Reset > Reset Network Settings

WARNING: This will reset your WiFi connections, so be prepared for that.

Another option would be to remove your simcard and put it in another iPhone. That will force the card to reregister. You can then switch it back to your device and it will force the registration again.

I have a question.

I had trouble yesterday with my phone acting up so I did a restore to when I first received it. Then I restored it from one of my backups.

Once I did that I could not see the little camera next to my txt message. I check the verison of ITunes and update to day on 9.0.1.8

In my about too I see

Verison 3.1
Carrier At&t 5.5

How can I get my little camera back in my txt. When it first came out it was working fine.

Any advice would be good. :(

Okay I figured it out. Once you reset your phone you have to go back into your setting for "messager" and turn on MMS message. Thats why I couldn't see the little camera...

[markie]

*#06# gives you your phone's IMEI number. International Mobile Equipment Identifier.

This is the phone's serial number and this code is standard on all GSM handsets - every last one HAS to respond to *#06# with IMEI.

Normally, IMEI shouldn't matter. IMEI is used to identify and (in other countries) ban stolen handsets. It shouldn't really have anything to do with MMS. This makes me wonder WHY AT&T needs the correct IMEI in their system to allow MMS. What trickery are they pulling and why bother? To make sure people can't SIM swap to another iPhone without telling AT&T? To make sure people can't use MMS on an unlocked iPhone on a plan for a different type of phone?

That makes no real sense...

Looks like people in the At&T west region tech office finally did their magic to my phone... about an hour ago a flurry of MMSs started spouting out of my phone... (countless at&t text sms as well as the one I had my friends send me on sunday)... Very happy that the wait ended up only being about 24 hours... much less than the 3 days that AT&T said it might take.

Best of luck everyone else! (I'm off to enjoy my newfound iphone mms-ness)

Because a lot of 3G/3GS users still have their 2G IMEI number in AT&T’s system, which causes MMS to be off. They have to go in and change that out for the correct IMEI so MMS can be turned on. I’ve seen a lot of people have that problem. How? I have no idea. lol.

Tried the Reset Network Settings on my iPhone 3G (j/b 3.1). No joy. I got the TXT from AT&T, saying MMS was now available. However, iTunes 9 finds no carrier update when I check. Guess I have to call AT&T...darn. :(
