Straight Talk with AT&T sim card

[tr88]

I had purchased the BYOP sim card (which originally was for t mobile) from ST, I have a no name brand from China, 6" with Jelly Bean. T mob sim card worked but I heard the ATT ones were better, so I was able to find one and put it in. My signal strength increased as well as my data, went from "Edge" to "HSPA". great, but now I noticed my MMS service doesnt work. I changed the APN settings per ST, nothing, I found a few threads on here too, changing the APN settings as well, and still nothing. Is this an ATT problem or I just havnt found the correct APN settings? Of course ST said its my phone, when in fact I had no issues with the t mobile sim. These are my current APN settings...

Name: straight talk
APN: tfdata
APN Type: default
Proxy: not set
Port: 80
MMSC: http://mms-tf.net
MMS Proxy: mmsc.tracfone.com
MMS Port: 80

Try MMS3. I think I saw that somewhere.

mms3.tracfone.com for the proxy

Got it to work, thank you. Anyone out there seen this phone in action? JXD X5? I cant find any info or accessory for it, case, or cover, nothing.

I already have these settings on two Nexus 4's and neither can send MMS. Any other ideas out there?

By adding Proxy: proxy.mvno.tracfone.com I finally have MMS working.
