i have a old sony ericsson, i need to unlock it for free since its a old handset, does anyone know how it can be unlocked or any software which is available for free which can do it
No you have to pay for the unlocking service. And dont go with softwares. Because it may spoil your mobiles or you may lose some data . Better you can use the code. This is the safe way of unlocking compare to others. If you wanna code, get it from your network provider or get it from www.mobile-unlocker.com/sony-ericsson-w880i/rs2wp9/ .This will help you to unlock your mobile easily.
