I am living in India and my uncle gave me a brand new Motorola DROID RAZR XT912 Verizon phone, but I have inserted a non-Verizon SIM and there is no signal and I got the following error message: "This SIM card is from unknown source".

I have enabled the GSM band with the help of this thread, but I couldn't get rid of the error message. I read in some forums that uninstalling the Verizon app may fix this issue. Is there any method to remove Verizon app?
