Quote,,the French manufacturer Wiko"...
Read this: ,,Shenzhen Tinno Mobile Technology Corp. ... est une entreprise chinoise spécialisée dans le développement et la construction de smartphones Android. ... Elle ne distribue pas des produits sous une marque unique mais sous des marques propres à chaque pays. En France : Wiko. Allemagne : Mobistel. Inde : Intex, Micromax." (Source: Wikipedia.)
