I set a 4 digit numerical password on my 8700V to be entered whenever keypad was unlocked. I removed my SIM and sold the device – forgetting about the password. I have just heard from the guy who bought it who claims that it is asking him for the password. I have given him the password I set but he says that it will not work. The device is unlocked and so will work with any SIM and so this is not the issue. Do I need to put my old SIM back in the device to remove the password? Is there a generic password for the device such as ‘0000’ etc? What else could the problem be?
