I'm at my wits end I have a Samsung Infuse that I activated on Straight Talk. The phone was factory reset on Sunday. I activated ST last night. I have tried every combination of APN's I can find. NOTHING is working. I still have no internet or MMS. One thing that I am finding is that in the APN type, I don't have the option to type anything. I can only choose one of the presets which are" internet+mms+supl, Internet, MMS or SUPL. I have tried not entering anything but the information ST provided and it automatically fills that field to internet+mms+supl. None of the options are working. I spent 45 minutes on the phone with ST today and they assured me everything is set up correctly on their end although who knows if that is truly the case. I also tried another suggestion posted in another thread which was to use H2O. I tried that and it still didn't work. It did however give me the ability to delete the AT&T APN settings which I hadn't been able to do previously. Can anyone help me with this? I am really new to this (obviously) and really need help. Thanks!
