Hi
Im a little new to all this, but have been keen to get the settings working.
I have tested the new version of SWIRLYMMS 3.3.3 and have sent and received. I have not installed a viewer yet so I cannot check what I have received but i can send and receive.
The latest version still seems a little unstable and some times fails to start but here are the settings that work
Edge settings APN orangeinternet no username or password
In MMS Settings
MMSC

Good Luck
