In 2020, 64% of supplier invoices were received electronically, equal to an increase of 9p.p. compared to the previous year. In the same year, we also saw significant growth in the use of eSIMs, with several thousand users already using this technology.
During 2020, use of electronic invoices by our customers increased 12p.p. to 73%, while applying to do this was made possible via digital channels. At the end of the year, 81% of users of 3P and 5P services (services which include at least television, internet and telephone) out of a total of more than 1 million customers, were already receiving electronic invoices.
NOS was the first operator to produce SIM cards from 100% recycled plastic and made from waste resulting from the industrial production of packaging and printing materials. Also in 2020, NOS focused on de-materializing SIM cards, launching the first eSIM service on the Portuguese market.
