Hi Didier,
And Welcome to the forum!
It appears you are looking for tips to implement good warehouse and transport KPIs especifically on mobile telecom products.
It's possible to have some specific Logistics KPIs for some particular activities but 80% of the logistics KPIs are very similar whatever the activity type is: autmotive industry, retail, mobile telecom...
Did you check our website free KPI's page :
Logistics and Supply Chain KPIs
It can be a good start.
And you'll probably be more specifically interested in our
Warehouse KPIs and
Transportation KPIs.
You can then adapt those KPIs to your activity specificity,
Hope this help,
