T-Mobile MMS Settings For iOS 5 and iOS 6

The MMS settings for T-Mobile on iOS 6. These are the exact same as iOS 4 and iOS 5. Currently the easiest way to get MMS working on tmobile is to jailbreak and install the fix from our repo.

Now what happens if you have an unlocked iPhone 4S running on T-Mobile like I do? Well, right now there is no way to jailbreak the iPhone 4S and so you can’t get MMS working. Don’t worry, LEI Mobile has your back. If you have a factory unlocked iPhone and DO NOT want to Jailbreak or can’t Jailbreak but want MMS settings for T-Mobile I have a solution.

First off here are the correct MMS settings for T-Mobile on iOS 5.

Jailbreaking Required Settings:

Please add our Cydia repo to find the iPhone MMS Fix for T-Mobile.
Our Repo is  http://beta.leimobile.com/repo/

To install our repository you will open up Cydia. Click on Manage at the bottom. Click On Edit in the top right. Click Add in the top left. Type http://beta.leimobile.com/repo/ and then press Add Source.  Then Click on the LEI Mobile source and install the T-Mobile MMS Fix or the Simple Mobile MMS Fix if you have Simple Mobile.

Once you install the fix you will need to reboot your phone and go into Settings->General->Network-> Cellular Data Network and make sure the APN is correct for both your data APN and your MMS APN. All other settings should be filled in. Depending on your plan you may have different settings. If you don’t know the correct settings try them all.  The most common is epc.tmobile.com and wap.voicestream.com. Others include internet2.voicestream.com and internet3.voicestream.com

Here is a video to help out:

UPDATE: This method will work on the latest version of iOS including iOS 6

Now if you have a factory unlocked iPhone and do not want to jailbreak to get MMS working on T-Mobile you can do some tweaking to your backup files.
1. First things first. Make a full backup of your iPhone in iTunes.
2. Download the program iBackupBot. Make sure to select Mac or Windows. You may use the free trial, but it is best to purchase!
3. Launch iBackupBot and just hit OK to all of the messages that may pop up. It may take a while to load all the device information if you have multiple backups saved on your computer.
4. Once loaded you will want to find your most recent backup on the left had side and select it.
5. Next you will see a list of files show up in the right-hand box. Scroll down until you see Library/Preferences/com.apple.mms_override.plist.

6. Double click on the mms override.plist and it will pop up a box to edit the file.
7. Download this com.apple.mms_override.plist (mirror link here) and paste the contents into the box or manually write it out based on the picture below. Then Save and Close the file.

8. Now put a check mark in the box next to Library/Preferences/com.apple.mms_override.plist and then click on File at the top and select restore.
9. iBackupBot will restore this new edited file onto your iPhone. Make sure you set your APN correctly and all of the other info is filled in. The cellular Data APN can be whatever T-Mobile gives you. The MMS APN must be wap.voicestream.com.
10. Reboot and enjoy MMS picture messaging on T-Mobile!

  1. Tom says

    i just download the trail version and followed your steps through 4. I can’t open my iPhone 4S 64GB backup files. It says “Invalid domain size at 3D5B:Users/tom/Library/Application Support/MobileSync/Backup/…../manifest.mbdb” can you help me on that please?

  2. Sam says

    I have iphone 4 on ios5 factory unlocked. Followed the procedure and now I am able to receive the mms but not able to send it. Before on ios4, I was able to send and not able to receive. Any clue?

  3. Ema says

    I bought the unlocked iphone 4s from apple.
    There is no need to jailbreak my iphone since I bought it unlocked. How can I fix the MMS issue. Do I need to download cydia or whatever that is….


      • Pankoy says

        I bought iphone 4s factory unlocked 32GB with the same problem; can sent but not receive MMS. I followed the instructions very carefully using ibackupbot and viola I CAN NOW SEND AND RECEIVE MMS FROM ALL CARRIERS AND ANY PHONE. Thank you so much LEI Mobile.

        However Group MMS doesn’t work. I am into group messaging and i really need this feature. I can do group msge with iphone but not when there’s any other phones in the group. Some of my friends don’t have iphones. Is there a way we an fix this feature for 4s factory unlocked iphones?

    • Pankoy says

      I changed mms_override.plist from GroupModeEnabled FALSE to TRUE but no change noted in group messaging. I still cannot activate group messaging.

      • helper says

        Pankoy, open cydia and install Tetherme it will have you respring. Respring and then REBOOT then when you open it will edit the files for you automatically and fix it. That what i did and my mms works great

  4. Jordan says

    Does anybody know if you do the method where you do the backup file on the computer if that restores your phone or just that mms file that you change?

  5. Kev says

    I have an iphone 3gs with T-mobile service. I bought off of a friend and it doesnt have Cydia or any jail break stuff so i presume it is “factory unlocked” It runs IOS 5.16.05. I copied the above formula into my iBackup and pressed restore, but it still did not fix my problem. I still cannnot send or recieve. IVE TRIED EVERYTHING!!!!!!!!!!!!!!! PLEASE HELP ME…Im so frustrated and have spent at least 12 hours of research and typing in codes, all for them to not work. Any ideas?
    PS: when i tried to download that file it sent me to filehippo which wanted me to take a survey or download stuff in order to use the file. Is this normal?

      • Jordan says

        When I used to have a 3GS mine was jailbroken and I used iFile to get mms to work. I would jailbreak it because that worked for me.

      • Mark says

        99.9% chance your phone is already Jailbroken since the only 32GB 3GS iPhones sold in US stores were SIM locked to AT&T I guess there is a slim chance your friend bought it unlocked from over seas but I suspect not. That being said if your device is JB then install Cydia and use the lei mobile repo as described above.

  6. Andrey says

    After doing all that i press restore and than a message pops up saying ” Error Occurred, error code 19″ whats that? what should i do?

  7. Kev says

    AHHHHH!!!! I have been trying to jailbreak my phone ALL DAY!!!$27 and 8 hours later and I still dont have it jailbroke. I first bought Cydia from iphone-unlocker-pro.c o m. Then it instructed me to download 2 files. One of which is redsnow and the other is a IPSW file. I did both and then ran redsnow and started the unlock. But when it reboots my phone it stops and says “unidentified builds.” I then read i could manually find the IPSW file and insert it. I have tried all sorts of files specified for 3gs/ios 5.0.1 and I cant even find them in my directory! Im running ios 5.0.1 and people are saying to get a 5.0 ipsw file. I then found and saved a 5.0 ipsw file to my desktop which opens itunes when i click it. It then says to hold shift and click update or restore. That then opens the directory. I then select the new downloaded file that opened itunes. It starts to update then says a problem occured. IM SO FRUSTRATED AND LOST AND CONFUSED!!! I dont know enough about this and have read EVERYTHING on the internet. Someone please save me. Thanks in advance ; )

  8. Kev says

    OK so I got Cydia up and running and now working on the MMS fix. But realized a fairly big problem. When i turn my phone off the only way to turn it back on is to run Reds0w and do a tethered boot. If i jsut try to turn the phone back on normal all i get is the apple icon. any ideas?

  9. Mark says

    the iOS5 jailbreak is currently tethered and you need to “Just boot” tethered with redsn0w every time your phone reboots. That’s not always easy to do if your phone reboots while away from home!

  10. Kevin says

    I restored the phone and everything has gone smoothly except I have followed all of the above instructions and my mms still does not work

  11. Lucy says

    Hey man,

    I’ve searched for hours for a fix to the mms problem last year and I’ve had to live without it for the past year because I couldn’t figure it out. I stumbled upon this because I was updating my OS and I’m glad I did, just the simple fix from your repo and now I’m up and running. Thanks so much for taking the time and doing this.

  23. Jeff says

    this just worked perfectly on a factory unlocked 4S, thanks! being able to receive mms was my last hurdle.

    a few notes:
    1. I have these settings: http://support.t-mobile.com/docs/DOC-2383 and so I was already able to send mms, just not receive them. I left these settings in place when following the above guide.
    2. facetime and imessage already worked for me. I’m on a T-Mobile prepaid (monthly 4g) account. The trick is to make sure you have some extra money in your account so when you try to activate imessage and facetime your phone can send and receive a few international texts in the background.

  24. Kim says

    thankssssssssssss so much for your details of step by step. I”m slow but were able to follow your instruction. thanks and thanks

  25. Lucy says

    Mine is updated to 5.1… iMessage will NOT work, no matter what I do. I’ve already done a full restore and have tried every trick in the book. Even talked to Apple and they can’t figure it out. It just says “waiting on activation” and is stuck there. Any advice?

    • Ben says

      Lucy, the iPhone makes a couple of international texts to set up iMessage. If you don’t have enough funds available if using a prepaid plan or you have international texting blocked, it can’t finish setting up the phone.

      • Lucy says

        Oh… that may explain it. I do have a prepaid plan but iMessage and Facetime still worked for me when I switched from a regular plan to prepaid on 5.0 though. Last night I did a full restore thinking it would work but it doesn’t lol. I am so tired of this!

      • Lucy says

        Would I have to go to the store to re-activate? I am now on another phone… Am returning it tomorrow so TMobile can still reactivate the micro SIM, I am assuming? Thanks!

        • says

          If you deactivated the sim you will need to reactivate it or get a new one. If it still has service you can put it into a new phone and it should work just fine.

          • Lucy says

            Well what they did was this: Since the SIM card was in an Android that I used for like a day, the sales rep. cut it to make it into a Micro-SIM and now it’s in my iPhone now. Facetime and iMessage are still trying to activate… Let me know if you have any further details. I want to take this up to Apple but not sure if they can help.

          • Lucy says

            Hey again.. So I restored my phone from my most recent backup and now Facetime works. Imessage still has that error. Do you think it’s still the int’l texting if Facetime is fine or really a glitch in the iMessage system?

  26. Craq says

    Holy $#!@ it actually worked for receiving!
    I have tried SO MANY things that never worked.
    But now I can’t send (I could before). ARGH How can I undo this? Just uninstall?
    iPhone 3G (with the 4.2.1 06.15.00 Firmware)

    • Craq says

      OK I tried clicking on the red (!) like a zillion times with 3/5 and 4/5 bars of service and no dice. Then at 5/5 bars eventually it worked. Dunno why it it’s so picky tho. I used to sent pics with only 2 bars before with no problem.
      Ah well anyway IT WORKS!!
      THANKS LEI!!
      PS I have the epc cellular data APN and the wap MMS APN.

  27. Jess says

    For some reason it’s not working for me, I must have tried at least 4 times. And I noticed that its because iBackupBot isn’t saving the newly edited plist…has anyone had that problem or can try to help me please??

  28. Jess says

    it’s not working for me, I must have tried at least 4 times. And I noticed that its because the newly edited plist isn’t being saved…has anyone had that problem or can try to help me PLEASE!

  29. Jess says

    It isn’t working out for me; I must have tried at least 4 times! Then I noticed that its because the program isn’t saving the newly edited plist. Has anyone come across this problem or can try to help me PLEASE?? (using a Mac by the way)

  30. Mike B says

    I can receive picture messages, but when I go to send progress bar gets 90% of the way there, but message does not go through. Any ideas? iPhone 3GS 5.1. Thanks.

  31. Mimo says

    Got a 4 running 5.1.1 with 4.10.01 preserved baseband jailbroken and with a gevey working on Tmo my son.

    After countless settings… I tried this and now it sends/receives MMS.

    Cellular Data
    MMSC http://mms.msg.eng.t-mobile.com/mms/wapenc
    MMS Proxy
    MMS Max Message Size 1048576
    MMS UA Prof URL http://www.apple.com/mms/uaprof.rdf
    Leave Username and Password empty

    Hope this works for some of you folks as well.

    I tried getting iMessage and Facetime to work. Found some intructions, did it and it ended up deleting my MMS settings and the camera icon was gone from the text part. Had to go back and delete the iMessage/Facetime stuff and enter this MMS info again. It’s working just fine the second try.

    Good luck!

  32. AR says

    I have an iPhone 4S running ios 6. I followed the iBackupBot steps above exactly but the MMS still does not work unless the “Cellular Data” is turned on. I thought the whole point of this was to get MMS to work without using the data plan. Am I missing something? Please help.
