In case of using CDMA 450, LTE 450, LTE Cat.M or Cat.NB (Narrow Band) networks
–
always use the proper antenna which is harmonizing to the frequency/band. In other
way the router will not abble to access the cellular network.
If there is no SIM slot
In case of using CDMA 450 network in many countries there are no need of usage of SIM
cards. The identification of the routers (their cellular modules) and the registration to
the cellular network is executing by a completely different way and method. Therefore,
on M2M Router CDMA450 version we do not provide SIM card slot. If your mobile
network provider requires a SIM card upon this network, contact us before ordering.
