Page 52 NB3720 User Manual for NRSW version 4.4 Conﬁguration A SIM card is generally assigned to a default modem but might be switched, for instance if you set up two WWAN interfaces with one modem but different SIM cards. Close attention has to be paid when other services (such as SMS or Voice) are operating on that modem, as a SIM switch will naturally affect their operation.

Page 88: Quality Of Service
User Manual for NRSW version 4.4 5.4.5. Quality Of Service NetModule routers are able to prioritize and shape certain kinds of IP trafﬁc. This is currently limited on egress, which means that only outgoing trafﬁc can be stipulated. The current QoS solution is using Stochastic Fairness Queueing (SFQ) classes in combination with Hierarchy Token Bucket (HTB) qdiscs.
