Let’s say you leave your Nokia E-Series device at school and don’t want your classmates seeing those luvvy-duvvy text messages you send to your girlfriend. Or maybe you can’t find your phone and don’t want anybody using it. The Nokia E-Series device has a great security feature called Remote Lock built in. Many people overlook or don’t notice this feature, but I think it’s a must-have for everyone with an expensive smartphone and sensitive data.

What does remote lock do? It allows you to send a unique message to your phone from another phone and it will lock.
