+This is a modem module that is sold pre-certified. 
+
+Different models come in different speeds, such Cat 1 up to Cat 4
+
+Drivers:
+ * option (at commands), cdc_ether (wwan)
+
+The modem can be configured to be in different modes. Mode 0 states in a manual that it cannot be used for data traffic.
+
+Mode 3 works with data traffic and can be changed with AT commands to /dev/ttyUSB1:
+{{{
+AT#USBCFG=3
+AT#REBOOT
+}}}
+
+lsusb should show: (may change depending on variant)
+{{{
+ID 1bc7:110b Telit Wireless Solutions Telit ME910
+}}}
+
+Verify the modem is detected with the lsusb command. Then use modem manager to bring the modem up with the following example:
+{{{
+mmcli -m 0 # Look for a large output of information about the modem
+mmcli -m 0 --enable
+mmcli --modem 0 --simple-connect="apn=hologram" #replace hologram with actual APN for SIM used
+dhclient wwan0 
+}}}
+
+A fully connected modem shown below with mmcli -m 0 as an example:
