Hi there. Got a problem with a BLU T200 Dejay, a rather new brand on the market. When the keypad is locked, it says to use '#' or 'send key' to unlock it. However, that doesn't work for me. Am I missing something. Does anyone have experience with that? BTW, I don't know if it makes a difference, but there is no sim card in it yet. I wrote to the manufacturer; they say I need to update the software ??? Weird. Thanks for your tips.
