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.

  3. Hi all, I’m using an unlocked iphone 3gs for tmobile and dont have picture text msg as default (even tho I had it before with my old samsung phone provided by tmobile). then I tried both US MMS settings they posted on here:

    APN: wap.voicestream.com
    MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
    MMS Proxy:


    APN epc.tmobile.com
    MMSC http://mms.msg.eng.t-mobile.com/mms/wapenc
    MMS Proxy

    both worked for sending pictures out, but not receiving them. I got the msg “the media content was not included due to a picture resolution or message size restriction” for both cases when my friend tried to send me picture text messaging. I also check out the xda phone link that Mike provided but it didnt work with iphone either. any resolution yet?

  4. Has anyone figured out what Tigger asked? This is the same problem I am having. Thanks!

  5. The FIX to send & RECEIVE!!!

    This is how to do it. My phone spec is 3g 16gig 3.0 firmware jailbroken with Tmobile WITHOUT data plan.

    1. Open Cydia and search for “Legacy” – Install the first one on top. (TMobile US)
    2. Once installed you’ll need to reset your network settings. Settings > General > Reset > Reset Network Settings. Confirm
    3. Now go to Settings > General > Network > and make sure Data Roaming is set to ‘On’
    4. Now go to Cellular Data Network > and enter the following:
    5. APN: epc.tmobile.com for MMS This SHOULD be wap.voicestream.com
    6. APN: wap.voicestream.com for Cellular Data
    7. MMSC:
    8. Proxy:
    9. Go all the way back to Settings and then press Home.
    10. Turn off the phone.
    11. Wait for the phone to completely power off, wait 30 seconds and then power back on.
    12. If your phone crashes and you get the Sad Phone Face, it’s fine, unlock the phone and reset the Springboard if need be.
    13. Now have someone send you a Picture Message and make sure you can send out MMS.

    PLEASE NOTE! ~ Follow it step by step. I started without installing the application and it displayed the same message to big message. Followed the instructions precisely and up and running. Sister w/ verizon sent me a picture message.

    Here’s the link I got it from after scouring the internet for a while:


  6. Also, my Data roaming is set to off now and it still works.

  7. hey scar thanks so much your help really did work for me!! :)
    But I have a question, my carrier is T-Mobile and I have unlimited texting, now that I can send and recieve pics will it overcharge me?

  8. actually my question was for jaren about the MMS..if it does cost money or not.
    and yours actually worked for me thank you SO MUCH!! :D

  9. EXCELLENT !!! many thanks to Jaren, it works now woohoo. just follow the instructions step by step and it works perfectly, no crashing or anything for me. good jod, great help :-)

  10. @ Loryn

    Texting is either MMS or regular, so you’re covered. If you didn’t have a texting plan, the 20cents per would apply to either your regular plan or flex account

Put T Mobile sim in phone in Dubai and it worked fine using their network DU – received and made calls and received and sent texts. Now I am back in UK nothing working. Profiles show china mobile – SIM accepted and shows T-Mobile UK. No-one here knows what to do – phone is not locked. It looks like the phone is not registering with T-Mobile – any idea what profiles I should enter into phone if any to make it work? Any help would be appreciated?
