Cellular Italia engineers every product, or develops it in collaboration with its technological partners, directly in Italy. From the earliest design phases, each project is developed by rigorously following strict principles of quality, reliability and respect for environment. Before each prototype goes into production, it is tested with every mobile phone to guarantee complete compatibility.

The tests involve detailed simulations of use which aim to verify functionality, efficiency and resistance. These tests are carried out at the Cellular Italia Research and Development Laboratories in Reggio Emilia.

Before being placed on the market, all products undergo checks and inspections in three different laboratories: in the factory where they are manufactured, in the laboratories at the group's main headquarters, and in the technical department at the logistics division. Every Cellular Line product undergoes all tests for certification under EU standards for sale.
