Neeed help with Straight Talk on HTC One X

I was using an At&t iphone 4 on Straight Talk for the last 6 months or so. I decided to trade for an At&t HTC One X because I just like Android phones better. Since I already have the ST sim, I figured I would get the APN settings from here and input them in and move on. I did just that, but cannot get the data to work. I can send/receive phone calls and text messages, but nothing on the data side.
I set up my prepaid StraightTalk AT&T APN settings as recommended below. Can someone help me find the error in my settings?

Name: straight talk
APN: att.mvno
Proxy: Not set
Port: Not set
User Name: Not set
Password: Not set
Server: Not set
MMSC: [Only registered and activated users can see links. Click Here To Register...]
MMS proxy: 66.209.11.33
MMS port: 80
MCC: 310
MNC: 410
Authentication type: Not set
APN type: Not set
APN protocol: IPv4
APN enable/disable: APN enabled (this is grayed out with a check mark in the box)
Bearer: Unspecified

Thanks for your help and Merry Christmas. :confused:

From what I can see, you're missing a proxy and some values need to be left blank.

Proxy should be "proxy.mvno.tracfone.com" (no quotes)
Port should be 80

My one x plus is giving me a *****!!

Still not working. There must be some kind of lock or something in At&ts system. I cannot get data to work on this for anything. Im gonna take it be an At&t store tomorrow to have them check the phone. This is not rocket science.

Is it possible you need a new SIM?

Well ST is more than useless. Their answer is to unlock my HTC One X and that will resolve the issue. I did and of course they were wrong.

I Have the same problem...I have a rooted, unlocked HTC OneX. I just ported my number over to Straight Talk wireless and the cannot get my Internet and messaging working... I have loaded thier APNs and ones ive found on the net but no luck. Under Mobile networks tab it says disconnected in light gray.. Please HELLLPP!!
