The Nokia 8110 4G has been updated for the modern age. With up to 25 days standby battery life on a single charge, there really is no need to worry about power. This phone is all about the iconic design, with a 2.4-inch curved screen being part of the overall look. The smooth slide mechanism gives you easy access to the tactile matte key mat. So, you can get back into the habit of tapping buttons with your thumbs.
