MMS settings for Straight Talk BYOP now that my 1520 is running Windows 10 Mobile.

I am trying to find working MMS settings for my 1520(ATT) that I have a Straight Talk SIM in. I have been searching and can not seem to find one that functions.

I had to reach out to ST for the info. I printed it out. Try this:

Internet APN
APN: tfdata
Username: ( blank)
Password: (blank)
Proxy server (URL)blank)
Proxy port: (blank)

MMS APN:
APN: tfdata
Username: (blank)
Password: (blank)
WAP gateway (URL): mms3.tracfone.com
WAP gateway port: 80
MMSC (URL): http://mms-tf.net/
MMSC port: 80
Maximum MMS size: (blank)

I hope this helps.
