No, it is not possible to use both modem and storage at the same time. Modem and storage can only be activated when the device is connected.
When I activate modem mode, the device switch Id from 1350 to 1365. Id 1350 also seems to be the default when neither storage or modem is activated.
ADB mode can be activated before plugging in, and it works in parallell with storage, but not in parallell with modem.
