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!

I can verify the settings below work. I work also recommend removing the unlockit profile and resetting network settings before inserting the t-mobile sim. The Internet will work without it once the manual settings are in.

FreddieMac,


Yes, pic messages are still working. After I made my entries per boonsfarm's values, I hit the "settings" back arrow (top left) until I got to the "Airplane mode" screen, then turned airplane mode "on", counted to 20, turned it "off". Repeated that another time. Then I tried to send a picture message to a family member's phone. When that finally worked, I turned the phone off and back on, and then tried another picture message.


When that worked, I backed up the phone thru iTunes in case it ever dissappeared on me.
