Everything needed to communicate content in a small volume.

For its small size this mobile does not interfere in a pants pocket, and yet its software contains everything that one expects to communicate simply; Obviously no touchscreen: for SMS is a bit longer but it still happens. Anyway, on touch screens, the virtual keys are so close, that the drafting of messages remains uncomfortable and devices are large and interfere in the pocket: you have a purse, even for men!
Note also a good battery because it uses less with his small screen.
Perhaps one of the last good "old" phone keys, advise without hesitation.
