Estou na dúvida de qual comprar. Estou mais inclinada para o Z80, principalmente por causa do desenho, do MTK6580 e das frequências de banda 3G (850 e 2100), mas a desvantagem é que não suporta cartão de memória como os outros dois. Minha segunda escolha seria o X01.  Bamos aveire :)

Todos os 3 funcionam independentes do seu smatphone porque tem slot para sim card.
