Sim Swap for MMS – iOS6 Version – Straighttalk

September 23rd, 2012 Leave a comment Go to comments

The below information has been sent in by a number of people in different versions so please let me know if there are anything I have missed/said wrong. I am not in the USA, don’t have an AT&T iPhone and don’t have a Straighttalk sim for testing any of this.

Please let me know if any changes have to be made to the instructions or any alternative instructions which you know work. What Type of iPhone you have might help as well (3GS,4,4S or 5) as these might only work with a certain model of iPhone.

This is similar to the old Sim Swap method some people used to use in iOS 5.1.1. Make sure you have the unlockit.co.nz Straighttalk profile installed first ( Go to http://www.unlockit.co.nz from your iPhone and follow your Nose) as this is the only way to set the Data Proxy needed (or some websites won’t work I have been told)

1. Close all opened apps
2. Place T-Mobile sim in iPhone
3. Open Settings, General, Cellular, Data Network
4. When Data Network Appears ( the screen will move back to Cellular)
5. Swap T-Mobile Sim to Straight Talk Sim
6. Wait for the “NO SIM” splash to disappear
7. Press Cellular again and Data Network should still be there.
8. Go to Settings and make sure the information below is entered.

Cellular Data

APN: att.mvno
Username:
Password:

MMS

APN: att.mvno
Username:
Password:
MMSC: http://mmsc.cingular.com
MMS Proxy: 66.209.11.33:80
MMS Max Size: 1048576
MMS UA Prof URL: http://www.apple.com/mms/uaprof.rdf

9. Press Cellular to Exit.
10. A restart of the iPhone may be needed. ( Hold down Top Button, slide to Power off and then start again with Top Button)

    Does the T-Mobile sim card have to be activated?

    phone: iphone 4S att unlocked
    current carrier: airvoice

    So, I feel like I’ve tried it all. I’ve followed the steps above very carefully, I get the appropriate menus, fill in the settings, etc. I’ve tried with and without the unlockit APN. I’ve tried leaving the MMS Max size and MMS url blank. I’ve tried entering the settings, rebooting; entering the settings, turning wi-fi on and off; entering settings, turning cellular on and off; rebooting at various points in the process…bottom line: data always works fine, MMS has yet to work.

    Any thoughts, tips, tricks I haven’t tried…I’d love to hear suggestions. Thanks for the help.

    I followed the steps exactly but when I inserted the Tmobile sim card I received a message that said “sim card failure”. Also when I clicked on Cellular there was no data network option-it just showed cellular data was clicked “on.” Any suggestions?

    The T-Mobile SIM does not have to be activated.

    If iPhone is running iOS 6 you need the new APN settings and are found on Straight Talk home page under support. Just noticed them yesterday. I put T- Mobile sim in and got the network tab and opened up APn page. Deleted t-Mobile settings and put the ones from Straight Talk took out TMobile put Straight Talk sim and every thing worked just fine. This was on a unlocked iPhone 4s.

    Thank you sooo much it worked! I bought the Tmobile sim card (oh no that came free just buy any item from the store for $20 – you might as well since its going to cost $20 just for an empty sim card). I am nontech savvy but I can follow instructions, so anyone can do it! All of these were done on iPhone 4s running on ios7, woot woot again, big thanks to the people behind this!

    This worked perfectly for me. I have an iPhone 4S that I bought unlocked with the intention of using Airvoice, but couldn’t seem to get the cellular data to work. I saw someone else mention that the phone still “thought” it was on the att network and so didn’t give the option to change cellular data networks. (Good ol’ iPhone not giving you options you don’t need ;-) Sure enough, borrowed a friend’s t-mobile microsim and swapped it out with the airvoice one. Presto! Success!

    I bought an iPhone 3gs off a friend as it is a big upgrade for me using an android phone from straighttalk. I was constantly having phone issues. Anyway, I was told by straighttalk in order to swap it over I needed to buy a sim card from them. I did so. I got it in the mail today and immediately put it in my iPhone, called straight talk and had my account swapped over. I could make/received calls and texts but I couldn’t do pic texts or use the internet data, only wifi. I downloaded the apn changer from this site and went to look for the setting in my phone to be able to change the apn. It was already done and my phone is working perfectly now. I will report anything wrong if it happens. Thanks so much for providing this service!!!
