I have a 1520 utilizing the tfdata apn but my mms settings aren't working. Anyone have the correct MMS settings?
Was fighting with the same issue with my unlocked 520 Win8.1 on Straight Talk (AT&T Sim.)
Here are my settings that work...
Internet APN:
APN = tfdata
(all others blank)
MMS APN:
APN = tfdata
UserName = (blank)
Password = (blank)
Authentication type = PAP
WAP gateway = mms3(dot)tracfone(dot)com
WAP gateway port = 80
MMSC (URL) = H tea tea pea (colen)(backslash,backslash)mms-tf(dot)net(backslash)
MMSC port = 80
Maximum MMS size = (blank)
IP type = IPv4v6
Sorry about the workaround - wp thought i was posting a link and I wouldn't let me reply...
Hope it works for you!
