I simply cannot get mms to work using this method. Data seems to be working ok. I can get the SIMs swapped quickly enough to get into "Cellular Data Network" with my Straight Talk SIM installed. Then, I toggle between "Notes" and "Cellular Data Network" until the defaults auto-fill.
I enter the settings as instructed here, and I've tried every variation of MMSC on here. But if I try to send myself a picture message, I just get "not delivered". Every single time.
If I back out of "Cellular Data Network" after entering the info, the "Cellular Data Network" option dissappears from menu -- is that normal? I have not toggled airplane mode yet... I was hoping to verify that MMS was working before doing that.
Thanks in advance for any help you can give!
