Sim unlock PIN disable
 

I am using my 8900 on Cable & Wireless in Panama.

Everytime the bb is rebooted, it asks for the 4 digit PIN.

I have tried to disable security in the options/advanced options/SIM card menu but I get back "Unable to disable security".

Does anyone know of a way that I can force the security to be disabled?

I want to use this sim in a GSM gateway and when I enter the PIN in the GSM/Voip gateway, the device does not register with the network, I have tried the MV372 with an unlocked SIM and it works fine.

Any help would be appreciated.

Thx
