Carlo, My understanding is that a phone will only ask for PIN code if it is in "PIN check" mode, which is optional, and is usually turned off by default. The PIN check mode is optional extra security you set if you want to make sure nobody can pick up your phone and look at your information or make calls. This is generic GSM information, not specific to Neo.
If the PIN check mode is set, on power-up the phone will ask for the PIN. If the PIN is entered incorrectly many times (usually ten times) then it will ask for a PUK code (Pin Unlock Code), which your wireless provider has. If the PUK code is entered incorrectly several times then the SIM card will permanently lock. This is expected behavior, to prevent someone from using a stolen or found phone. At least this is how it works in North America, but GSM is a global standard, so should be true there also. So my question would be, why is it asking for a PIN code at all? If not in "secure power on" aka "PIN check" mode it should not require a PIN code. I suggest, put it in regular phone, go to phone settings and turn PIN code check mode off. Then put the SIM back in Neo and try it. Regards, Doug Sutherland Proficio Research http://www.proficio.ca/
