hey all. i recently received a 8820 off ebay, which since receiving, i have managed to unlock successfully. but now that the phone reads my tracfone sim, it wont make any outgoing or receive incoming.it reads SOS and there is no signal strenth. im sure the sim is good because it still works in my original phone. i have the desktop maager and the latest software installed. i was thinking that the sim just isnt compatible. i've even gone into the phone and removed the it policy, so any suggestion would be greatly appreciated.

go into options, advance options, SIM card, while in there type MEPD(you will not see text appear as you type)... some new text will appear on the screen... make sure they all says disabled or inactive...

if they are not ALL inactive then your device is not unlocked...
