Straight Talk APN Settings for Internet and MMS for At&T Samsung Galaxy SII Skyrocket

I have a HTC evo 3de unlocked on straight talk service plan with a straight talk sim card they sent me .. why want it hook up to the att tower near me but everywhere else? what do i need to do ... please help been two weeks at this. thanks
 
Mine is an international unlocked version N7100 that is on ST's at&t network. I entered the settings for the APN and it still didn't work :( my MMS isn't working. My data is good.
 
Yes it is working fine. I just did the changes you mentioned. Thanks for the help. I am using Straight talk AT&T sim card.
 
I've got the samsung galaxy s2 mjellybean 4.2 from at&t unlocked, with a Straight Talk tmobile sim, absolutely nothing I've tried is working. I have no idea what I'm doing wrong.
Here is what I have in my apn settings as of now.

Name: T-Mobile US
APN: epc.tmobile.com
Proxy: Not set
Port: Not set
Username: none
Password: ****
Server: *
MMSC: http://mms.msg.eng.t-mobilr.com/wapenc
MMS proxy: Not set
MMS port: Not set
MCC: 310 (it wont allow me to change this?)
MNC: 260 (it wont allow me to change this?)
Authentication type: Not set
APN type: Not set
APN protocol: IPv4 (it wont allow me to change this?)
Enable/Disable APN: APN is enabled. (it wont allow me to change this?)
Bearer: Unspecified.

If anyone can help me with this, I'd greatly appreciate it. As of now my cellphone is my only way of accessing the internet, now that its not working, I've had to stay at my grandparents and friends's house just to get on the web.. :-\
 
I finally got MMS running on my Skyrocket with Straight Talk AT&T SIM. This is what I'm using in the APN:

Name: Straight Talk
APN: att.mvno
MMSC: http://mmsc.cingular.com
MMS Proxy: mms3.tracfone.com
MMS Port: 80
MCC: 310
MNC: 410

Everything else is not touched.
 
i have an HTC inspire 4G which has been working for the past couple months. i had to factory reset it and now i lost my APN settings. i tried using the ones from the straight talk website, but they're not working. any suggestions??? i can use the internet when i'm connected to wifi, i just can't get connected to the network!
 
So if I change the apn settings given to me from straight talk will this mess up my phone?? I do not have good service or internet because they said if you use a sim card in my area i wont have 3g but if you use a GSM phone and get a code I could have 3g. Dont really know what to do! PLEASE HELP!
 
I have the GS2 skyrocket (AT&T ). Changing your settings will not mess up your phone. I have been having data issues lately also. When I found this thread, I changed the MMS proxy from 66.?( don't remember the rest of the numbers), to mms3.tracfone.com, It started working great again. I did not change anything else. Hope this helps. I'm in Louisville ,Ky.
