Why buy a mobile phone?

Above all one must first see what they really need, communication, a game console, video, etc., then the cost of maintenance and air time.

and now all bring camera phones, mp3, expandable memory, and a lot of functions, but not all are good economic and, most important brands are samsung, sonyericcson, Nokia and Motorola, are leading brands that offer good technology but only has the sony acceosorios their problem are too expensive, so a memory m2 comes up costing from 300 pesos 2miles according capacity when a micro sd costs from 100 to 400 by very expensive, because the difference? because Sony is a monopoly than it does good business but if we buy this brand must be consent to their maintenance is expensive.

I recommend the brand nokia, is not expensive, are very good teams and their accessories are not expensive, before buying Ask what you really need.
