The Nokia 2720 Flip boasts excellent durability and a timeless design, and is compact enough to fit in a pocket or a purse. It’s made of tough polycarbonate that’s strong enough to handle the knocks of everyday life. Incredibly, in this age of power-hungry devices, it delivers up to 28 days of standby time from a single charge. Yet this is no 'dumb phone'. Search the Internet, check the weather or get updates on the news with the help of Google Assistant. Its standout feature is an emergency button that sends a text message, including the current location, and calls five emergency contacts in the address book.
