To all with a Samsung Galaxy Note (SGH-i717),
OK here it is , after a lot of crap , if you are have trouble with slow/no download data speeds this is for you. First you need to be using Radio UCLF2 ( it allows the fastest data exchange). Secondly in your APN settings follow the instructions from Straight Talk , but where it has the " proxy " use 188.8.131.52 , where it has " mms proxy " use 184.108.40.206 or 220.127.116.11 , on the " authentication type " use " PAP OR CHAP " , reboot . OK check speed again , you should be good to go . Good luck and God bless , ib6469 .
