You get "Emergency Calls Only" for e.g. if the SIM operator's network isn't available at your place, and the phone connect to other operator's network. Or maybe you just don't have credit...
It is normal when a phone is unlocked by patch, because SETool, XS++ etc. read the SIM-lock from GDFS. The GDFS is still locked, but due to patch the phone believe that is is unlocked.When I using "Identify" feature in the SEToll, I"m getting:
"Network LOCKED".
