Enable MMS on unlocked iPhones

FlashGen.Com IconI like a lot of people have an unlocked iphone (not to be confused with a Jail broken one). So on installing the 3.0 update MMS was immediately available but I suspect, like me, for most it won’t actually be active (no little camera icon in Messages is an indicator if it’s working or not). If this is the case all you need to do is enter your MMS settings (a quick Google should provide you with the correct info – UK users can grab them here) via the steps below.

Access Point Name: general.t-mobile.uk
Username: user
Password: one2one
Authentication: Normal
Data bearer: GPRS
Gateway IP (proxy) address: (also
Session mode: Permanent
MMS Message (Relay) Server URL: http://mmsc.t-mobile.co.uk:8002/

  1. Go to Settings > General > Network > Cellular Data Network
  2. Scroll down to the MMS settings and enter the correct information, my T-Mobile settings are shown in the image. Don’t worry if you don’t have info for Max Message size or MMS UA Prof URL – these are usually handled by the carrier so you can leave them blank
  3. Once the details are in place you need to exit Settings and restart your phone (this is the important bit as the phone won’t pick up the settings have changed unless you restart)
  4. If everything is OK on restart you’ll have a little camera icon next to your message input field in Messages (plus you’ll now have an option to send images etc by MMS)

It’s worth pointing out that if you have an unlocked iPhone you don’t need to do any of the ipcc file hacking that a lot of the “beta” articles seemed to indicate. The MMS option should be alreay present and just need configuring. If you’re with an official carrier like AT&T or O2 etc the process may be completely different as it seems to require hacking the ipcc file to set certain values so your mileage may vary.

  1. Thanks so much for this – have a genuine SIM-free iPhone from Italy and have been searching for this all day!
    I’m on Three UK and have put the settings in but it doesn’t seem to work….get a red exclamation next to the picture after a lengthy ‘Sending’ wait. Do you know where I could get accurate settings for Three UK?

  2. Hi Andy. Mine is from Italy too. Glad this quick article was of use. I had the red exclamation mark a couple of times. Seems the iPhone isn’t as ‘robust’ when it comes to sending 3G data if the signal is weak too so you may see it on odd occassions, as this is the new ‘failed to send’ icon instead of the silly white bar and ERROR we are all used to from 2.x.

  3. Thanks for sharing:

  4. @Mike Thanks for the help. Got my tethering working using the excellent generator at http://tetherme.lstoll.net/ .However am getting exactly the same problem as you – after connecting to iTunes, the Tethering option disappears – though I’m left with a ‘Cellular Data’ section in my Network settings on the iPhone. Let me know if you find a solution!

  5. I have two factory unlocked phones from Italy using T-mobile USA. I notice that when I send picture messages from the resolution of the image is made smaller. Is there any way to prevent this.

  6. Ah, good man. Been looking around the net and trying to figure out how to enable MMS on 3.0. Haven’t updated my iPhone to 3.0 yet, so I didn’t know about that MMS menu. Oh, and for those people wondering what the T-Mobile U.S. MMS settings are….

  7. Hey, i have a iphone 3g 3.0 jailbroken and unlocked to t-mobile. I was wondering if any of yall have a configuration for the united states…. I tried the one thats on this website but i get a red exclamation point. Please let me have the setting for the usa one please… Thanks

  8. @Andy, I got the tethering to stick but not sure if it was because I just applied the profile again correctly or the fact that I tethered the phone via BT and then performed a sync while it was still tethered. Either way it is still showing the settings so all is looking good :D

  9. hi there, tried the t-mobile setting for mms but it does not work… I just get a red exclamation mark beside the picture. Any help?

  10. Hi Craig, are you using the UK or US settings?

    I had trouble sending images that I had copied and pasted in to Messages from my pictures folder (I’m on T-Mobile UK) – I suspect they have a max file size set on the server. Try sending an image that you have attached via the Messages “Choose Existing” option – I noticed that pasting an image leaves it as a PNG. However attaching it via the Messages “Choose Existing” option converts it to a JPG so I assume there is some internal compression going on. Let me know how you get on :)


  11. I’ve tried both US settings for iphone 3g and neither one of the work I am geting the same as craig a red exclamation mark next to pic. I am attaching the picture from shots I took with the phone. Can someone please tell me what I need to do to get the mms to work on this phone.

  12. I have a world wide unlocked iphone 3g I’ve been using on tmobile, I updated to 3.0. I use the .ipcc file and the teathering works great. I can’t get the mms working, I’ve tried different proxy settings etc, anyone get it to work for tmobile usa?


  13. It seems a lot of US T-Mobile users are having issues. I’m based in the UK (on T-Mobile) and haven’t really had any problems. If I find any more info on T-Mobile MMS settings for the US I’ll post them up.

  14. for tmobile users the mmsc is the mms proxy is the apn is the same as the others try it works good

  24. I have tried every mms setting for t mobile on here… What am I doing wrong? Is there any thing else I can try
    please help!! I would greatly appreciate it.

  25. I got the mms to work, and I can send the mms.. but i cant recieve them.. let me clarify.. i am in the US.. using an iphone 3g 3.1.2 firmware…. and i got the mms enabled with the EPC apn.. and I am able to send messages correctly, but when messages are sent to me it says the media content was not included due to a picture resolution or message size restriction.. any help would be appreciated

  26. Hi Keith, it sounds like your provider doesn’t sets the MMS size automatically – you may need to set it yourself in the MMS Max Message Size property in your MMS settings. Alternatively just give them a call and ask them for their MMS settings to make sure the settings you have are indeed correct – If that fails you may find them via Google.

    Of course worst case is your provider may need to enable MMS support on your account for you to receive them.

    Sorry I can’t be of more help :)

  27. Hi I am on the 3 network in the uk I have tried the above info but I still get the exclimation mark. I havent put in a user name or password is this where Im going wrong?
    Help me Obi Wan your my only help


  28. Just started with that stupid message of media cant be received for some reason or other.

    Just up you “MMS Max Message Size” to 24,000,000

  29. Thank you very much Andy M!!!! Mine finally worked on 3!!!
    Mart>>> Make sure you’ve got it all correct and switch off your phone and switch it back on. Try that ;)

  30. hi how can i do it for my phone mine is unlocked but i still have a no contract plan for at&t how would i do it then?

  31. Hi Orestes, MMS settings are carrier specific so until you have a contract with AT&T or another carrier you can’t really configure the phone. Once you do sort out a plan, you should be able to add in the carrier specific MMS settings as per the article (some carriers even do it automatically for you via an ipcc file). That said not all carriers allow MMS to be configured by the end-user – as some charge extra for these types of services so your mileage may vary.

    I don’t know what AT&T’s process is so I can’t comment of how, or if, you can configure your iPhone once you’ve sorted out your contract (or if all AT&T contracts include MMS), that said I’m sure a quick Google will provide the answer. :)

  32. I have an iPhone 3g unlocked on tmobile and i followed the instructions for the united states one and it allows me to send pictures but not recieve , what do I do?

  33. hi mike, i just got an iPhone on t-mobile in the UK and they say the password for mms is different to what you have said…i tried what they told me and both my internet and mms are not working as i’m apparently “not subscribed to a cellular data service” can you help?

  34. Now it saysVThe media content was not included due to a picture resolution or message size restriction. Wat do I do?

  35. Hi Cory, I’m not sure how to get it to receive MMS in the US as it might be carrier controlled. Here in the UK the system is automatic as long as your carrier has enabled MMS support on your account – i.e. you generally don’t pay extra for the service you just need it activated.

    The picture res / message size issue is down to the fact that the images being sent / recieved are generally “too big” for the MMS service. If you look a the MMS settings you’ll see you can set size restrictions etc, again over here in the UK it is usually done in the background so doesn’t generally need to be set. In your case you may have to put a value in those fields – have a google for T-Mobile US MMS settings (I found these details for XDAs on T-Mobile US which should be the same, although the property names may be slightly different on your iPhone – http://forum.xda-developers.com/archive/index.php/t-274193.html)

  36. Hi Alex, the settings are correct for contract phones (and as far as I am aware they are the same for PAYG). You don’t need a data package, but you will need them to enable MMS (which may include 3G / GPRS support too) for your number. Internet has nothing to do with it – I think they’re just trying to get you to sign up for extra stuff you don’t need.

    GIve them a ring back – phone T-Mobile directly, don’t go in to one of their shops as they are generally franchises – and ask to have MMS enabled on your number, once they say it is working (a quick click of a screen ;p) ask them for the relevant service details (I’d be surprised if they were that much different if at all), feel free to tell them you have an iPhone – I did and the customer support agent was very helpful. MMs activation can take a few hours so don’t expect it to work immediately.

    Bear in mind that they don’t have the exact settings for an iPhone as they don’t sell them so you may have to either write the info down or attempt to enter it as they are giving you it – or just use the info here as I’m sure it will be the same. I got them to give me the MMS settings based on an N95, as I used to have one, but the phone manual they use is pretty irrelevant to be honest as the general settings are the same regardless of what phone you have.

    I hope you getting it sorted :D

  37. scar you are a legend thanks for taking time to pose, mms works a treat on tmob uk. wanted this to work for ages. Not recieved any pics yet will it do that too?

  38. I have an iPhone 3G unlocked on T-mobile of U.S. I can send a pic text on MMS and English text. Now, I want to use international Language on MMS. I can type Japanese but I can’t receive and send them. What do I need??
