How To Fix MMS Problem After Jailbreaking And Unlocking iPhone On T-Mobile US

Unlock iPhone 4

Some of our readers who had jailbroken and unlocked their iPhone to use T-Mobile SIM in the US have complained that MMS doesn’t work.

We have some good news if you’re facing the issue. The iPhone hacking community has released a patch to fix the issue that can be installed from Cydia.

You can follow these instructions to fix the MMS issue:

  • Launch Cydia from your jailbroken iPhone homescreen.

  • Tap on the “Manage” Tab and then tap on “Sources” section.

  • Tap on the “Edit” button and then tap “Add” to add the following repo URL to add sources:

  • After it is successfully installed, tap on the “Search” tab at the bottom and search for ‘T-Mobile US  MMS Fix for iOS4’.

  • Tap on T-Mobile US  MMS Fix for iOS4.

    T-Mobile MMS Fix
  • Then tap on the “Install” button and then the “Confirm” button to install the patch.

  • If you launch the Settings app and navigate to Settings –> General –> Network –> Cellular Data Network, you should see the following settings under MMS:

MMS Proxy:

After your iPhone has restarted, MMS should be working on your jailbroken and unlocked iPhone on T-Mobile US.

As always, let us know it goes.

    Amazing fix. I'm gonna hope that they will be a kind of "international MMS FIX" for other phone provider like me here in Canada with Rogers, my MMS in my iphone ain't working since jailbreak.

    Cross finger here 🙂 And happy for the T-mobile users

    try to Reset network setting…


    We need a fix for ATT MMS after unlocking.

    I have check with many people and they have the same problem.

    I have reserached for 3 days to find a fix for ATT MMS with Ultrasn0w installed.

    After installing Ultrasn0w – ATT MMS will not work – After un-installing Ultrasn0w – it will work perfectly

    I have restore the iphone 4 with iOS4.01 over 10 times and with no other apps installed and with the same problem .

    Please help and let me know how to fix this problem

    Thanks in advance

    • bob

      AFAIK, ATT jailbreakers dont need Ultrasn0w. That is for those that rely on Unlock for a different carrier. So dont install Ultrasn0w when jailbreaking if your an ATT user and you should be fine.

      • tiger168

        That is not a fix. I have AT&T and travel outside of the country often and also having problem when I return to the state side and cannot send MMS via AT&T network with Ultrasn0w installed.

    • ron

      fixed mine and was so easy

  • Vishnu

    Its not working now, but used to work on my 3GS

    • Jonaladona

      Check and see if your APN settings are right,

  • Vishnu
  • Fences2312

    Worked great. I am on a 3Gs running 4.0.1. Great work.

  • Daniel323LA

    Settings>general>reset>reset network settings
    That should do it

  • anshul

    i m getting problem after jailbreaking n unlocking my iphone 3gs running ios4 —–my phone gets restard after every 2-3hrs and sometimes the brightness level and ringtone gets to default……..please help me out

    hoping to get reply as soon as possible…

    firmware – 05.13.04
    version – 4.0
    i m using vodafone INDIA network

  • Boinrite

    I have the same problem. After unlocking, MMS is not working with my ATT account (sending seems ok but not receiving). On my T-Mobile account, even sending is not working. Tried resetting network but still the same.

  • Tim

    Thank you for the information – I have tried this 3 times – it will not receive or send unless I un-install Ultrasn0w. Once Ultrasn0w is removed – AT&T MMS will sent and receive perfectly. I have done a complete new restore and install nothing except Jailbreakme and it works but once Ultrasn0w is installed MMS will no longer sent or receive – Once Ultrasn0w is removed MMS will work perfect again.

    Reset the network will no make any difference – Please help.

    This problem is with many iPhone4 only. No problem with iPhone 3GS.
    Thanks Again

  • Jeff

    Will it work for my simple network???

  • Geok1d

    need help!!!
    I have an iphone 3gs and had it running 4.0 but at the time there was no real solution to the mms issue. So i upgraded my iphone to 4.0.1 seeing as works with that ios as well. Well here is the problem it does not seem to work on mine. Ive tinkered with all the safari settings turning every thing on/off then restarting.

    Here is the problem that i cant get past, starts downloading and just when it gets to the second status bar that jailbreaks the iphone it crashes, every single time. Have been tinkering for about two days now and no progress.

    Extremely frustrated and almost to the point of just getting rid of it.

    Any help would be appreciated.

  • apelpapa

  • I have the MMS (camera) button on the left of my text, but when I try to send a picture, it pops up an exclamation mark by the picture. Help?


    I have tried this but still i dont see Apn option under my cellular data? what could be the reason

  • jake

    I had to enter the APN info by hand, seems to be working after that (3GS, 4.0.1).


    any luck with AT&T and not being able to send MMS? I can receive but cant send. on 4.0.1 4G iPhone

  • I just had the same problem, I reset the network settings, and removed the MMS UA Prof URL. Works perfectly.

  • Sux this ATT

    works good for tmobile 4.01 3gs
    1. reset setting
    2. Add n install repo
    3. instead of use
    4. Reboot
    5. Test send pic message to self

    • Killerdoll

      I have T-Mobile also. I can send Pics to other Ppl but can’t receive Pics. When I send a Pic to myself it works…So weird. I’m gonna try it with “”, hopefully it will work.

  • Santastolemypot

    I had this problem for a couple days now. i have an iphone 4 with 4.0.1 os. I was reading this forum, and i clicked modify on ultrasn0w, reinstalled and it works perfectly, i just got mms messages from awhile ago and even voice mail.

  • eric

    MMS will NOT work if you can see "carrier" section in settings.
    You have to switch airplane mode on then off.
    You will see it dissapear.
    If it still doesnt work after. reinstall ultrasnow from manage packages in cydia. you dont have to remove then reinstall just hit reinstall.
    This works for me…

  • jeff

    The MMS is working, however, I can only send one picture at a time. MMS close down if I were to attach more than one picture. Has anyone experience this or know how to fix it. Thanks

  • hey i`m having a question how can i unlock my iphone if i don`t have a sim ?please help i have a 3gs to, the latest version and i can`t use it it only works in itunes i can`t open it

  • idiot

    So what can somebody do that accidentally installed this package when they are using ATT and not T-Mobile? Resetting network settings and uninstalling package only gets calls and sms working but no 3G connectivity for internet.

  • you're a miracle!!! i've been trying to figure this out forever! now if i could only get it to stop respringing or whatever… it does it all the time!


    DUDE THIS FIX !!!! ROCKZ !!!!

    I literally spent 2hrs with T-Mobile customer service and 3hrs searching the WEB for a fix. I think I passed over this site at least 3 x's ( IDIOTA ) when I finally did scroll down and follow the instructions the fix honeslty took like 3mins and I can SEND and RECIEVE "MMS" on my unlocked/jailbroken iPhone 3G.

    Now if you guys can figure away to allow the folder storgae that iPhone 4 has there will be NO need for me to upgrade

    I'm posting this on EVERY SITE possible… Thanks

  • nvrblog

  • Frustrated T-Mobile iPhone User

    I must be doing something wrong.

    I've followed all the instructions but nothing ever appears in the Cellular Data Network area.

    I've tried many times to enter the information manually. After I restart, it is all gone. I've tried to reset the network settings, reinstall the fix, and when I reboot the phone, nothing appears in the Cellular Data Network area.

    Any help would be greatly appreciated. Thanks!

  • Frustrated T-Mobile iPhone User

    Nevermind. Got it working. Finally used:

    Data APN:
    MMS APN:

  • doku69

    I had to reinstall in Cydia (error code x 3 on the first round); after reinstalling, the phone asked for a reboot, which I did. Once it came back up I went into settings and I verified all the above listed network settings. Then I turned the phone off. Waited 30 secs, turned it back on, and everything works. I can now send and receive MMS with pics. Awesome!

  • Rob

    I did that and it said error and removed everything from my cydia. How can I fix that now???

    this works perfectly. I could send pic mms, before but all of sudden stopped. I manually input the following: (it worked perfectly)
