What do you mean? Can you describe your issue in more details? Does the phone show network and the level of signal strength?

Can you specify what network do you want to use this phone in? Gsm 900 or Gsm 850?
880A-AAAVAR1 - I guess this firmware is designed to work in 850/1900 bands...

I reckon that this is some problem with your gsm network... For some reason this phone isn't allowed to register in this network. Try to use Sim Card from another operator and post your result.
