Using a Smartphone? Nokia collecting patent royalty on 4G/5G as we speak.

On a Mobile Network? You can bet with very high chance some part of the network are running on Nokia. Broadly speaking carriers like to use every vendor they have in part of their network just to have vendors competing on price.

Using DSL or Fttx Fibre at at home, you can bet somewhere along that fibre there is an Nokia or your DSL Modem is Nokia.

They might not be a household name, but they are still everywhere.
