Band Selection This field appears if you selected a mobile broadband device that allows you to select the
type of network to use. Select the type of mobile broadband service for your mobile
broadband connection. If you are unsure what to select, check with your mobile
broadband service provider to find the mobile broadband service available to you in your
region.
Select auto to have the card connect to an available network. Choose this option if you
do not know what networks are available.
You may want to manually specify the type of network to use if you are charged differently
for different types of network or you only have one type of network available to you.
Select GPRS / EDGE (GSM) only to have this interface only use a 2.5G or 2.75G network
(respectively). If you only have a GSM network available to you, you may want to select
this so the Zyxel Device does not spend time looking for a WCDMA network.
Select UMTS / HSDPA (WCDMA) only to have this interface only use a 3G or 3.5G network
(respectively). You may want to do this if you want to make sure the interface does not use
the GSM network.
Select LTE only to have this interface only use a 4G LTE network. This option only appears
when a USG dongle for 4G technology is inserted.
