I have a problem trying to use another carrier instead of original.
For internet connection, I could set new APN and it was work well.
But, for MMS(multimedia message service), I could not found how do I set MMSC(MMS proxy), MCC, MNC, MMS related parameters.
In case of other OS for smartphone, usually it was found at APN setting menu.
How do I set MMS related parameter? Please help me.
