I am using a Samsung Galaxy S II with a BYOD sim card. The phone works fine (voice,texting, mms), but the data service does not work. I have set the APN settings according to the settings sent by Straight Talk. Anytime I try to connect to the web I get an error, Authentication via the proxy server was unsuccessful.
FYI, I have the straight talk service with sim card working on an Iphone, but I can't get it to work with this Samsung Galaxy S II (I777).
Thanks for your help,
