Este aplicativo é ideal para quem trocou de operadora ou possui contatos desatualizados, dificultando a realização de chamadas nacionais no Brasil. Ao atualizar sua agenda, o app faz os seguintes ajustes automaticamente: - Adiciona o DDD da sua região, quando necessário; - Insere o nono dígito (9) nos números de celular que ainda não o possuem; - Acrescenta o código do país (+55), se estiver ausente; - Remove o código da operadora (CSP), se presente, permitindo chamadas entre diferentes operadoras. Mantenha seus contatos padronizados e evite problemas ao realizar ligações nacionais.
