It would be very usefull for us to have a "selfactivation" option on our sim cards. Working in Motorsport we turn off every month all our sim cards and then in the following month we activate the ones we are going to use according to the calendar. Some of your competitors (kpn) offer the option of a "selfactivation" as soon as the device with that sim card is switched on. That would avoid us the required planning in advance and would make some last minute need easier to manage, especially on the field.
