LG E900 Optimus 7 MMS Manual configuration

LG E900 Optimus 7 - MMS - Manual configuration - Step 1
* The LG Optimus 7 will be provisioned autimatically with the right settings upon first usage with the BASE SIM card. * To verify this, send an MMS message to your own mobile number to test the settings. * If MMS doesn't work, reset your device to factory settings (via *Settings*, *About*, *reset your phone*). Unfortunately, manually changing the MMS settings is not possible in this case.
