After reading countless posts on many different forums, I am haven't found a remedy to my problem. I have spent hours messing with different APN configurations and none seem to work. By accident, I finally got the internet working by typing in "Straight Talk" in the "Name" field and touching home at the bottom of the phone. The H+ icon instantly appears, but I can't get the MMS to work. I have tried the 1 APN set up from this forum along with the 2 APN set up. What I do know is that every time I insert "att.mvno" into the "APN" field, the data stops working and still no MMS. When I inserted all the settings given to me by Straight Talk and omitted "att.mvno," the data works again but without the MMS feature. Here are the fields my phone offers:

Name:
APN:
Proxy:
Port:
User Name:
Password:
Server:
MMSC:
MMS Proxy:
MMS Port:
MMC:
MNC:
Authentication type:----->(options offered: None, PAP, CHAP, PAP or CHAP)
APN type:----> (options offered: Internet+MMS, Internet, MMS)

*I was very careful when entering the settings. Every cap. and punctuation was exactly as what was posted on
on here and other forums.

Thanks for your help ahead of time.
