The Alcatel 2003D Grey is very obviously a classic, old-school phone. You are going to love it if you want long battery life, simple controls and you know you will only use a handful of basic phone functions. It provides calls, text messages, plus the standard stuff like an alarm clock, planner and so on. Another necessity is Bluetooth for linking your phone with other devices. To make the phone even more practical, you can use two different SIM cards at the same time. The connectivity options include Jack (3,5mm) and USB micro.
