Invalid sim card indicates that your blackberry 7100g is locked with your current network . So, you need to unlock it to use other sim cards with it . You can get unlock code from your carrier or from any of the online service providers like http/www.unbblock.com/blackberry-7100g/rs18wp9/ to unlock it .
