Powering Your USB Modem
Your modem is designed to use the power supplied by your USB port. In
some modes your modem may draw up to 800 mA. If your USB port is not
capable of supplying that much current, you may use the supplemental
Micro USB port on the side of the unit for power or you may reduce the
transmitted power using commands to the modem. For more details, please
see www.zoomtel.com/power .

Using Your Modem for Raspberry Pi or Linux
Connecting your modem on Raspberry Pi or other Linux distributions,
including embedded Linux OS’s such as BusyBox, is controlled by the PPP
dialer command pppd. The steps below were tested for Raspberry Pi, and
other versions of Linux should work the same.
1Plug your modem into an available USB port. Raspberry Pi users may
need to use a USB extender cable to allow access to the other USB
ports.
2From a terminal window on your Raspberry Pi or Linux computer enter
sudo su to elevate you to root access.
3Install the ppp package by entering the following command apt-get
install ppp
4Next you will need to create two scripts that pppd will use to create
the connection. You can either create the scripts using an editor such
as vi or download the scripts from www.zoomtel.com/4630support
5The first script should be named zdial. If you downloaded the script,
copy it into /etc/ppp/peers
6If you are creating the scr. Theipt, put the contents below into the
/etc/ppp/peers directory.
#module configuration
/dev/ttyACM0 460800
#pppd options

#logfile configuration
logfile /etc/ppp/ppp-logfile
record /etc/ppp/ppp-dumplog
#call to chat script
connect '/usr/sbin/chat -v -f /etc/chatscripts/lte_dial'
7The second script lte_dial should be placed into the directory
/etc/chatscripts/ The contents of that script are below:
#abortstring
ABORT BUSY
ABORT VOICE
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "NO DIAL TONE"

8To connect to the Internet, enter the command pppd file
/etc/ppp/peers/zdial. Once connected, you can try pinging a known
website. If it works, Congratulations! Your installation is complete. If
your modem is NOT working, please see Troubleshooting your
Internet Connection below.
Note: If you are already connected to the Internet using the Ethernet
port of your Raspberry Pi, remove the Ethernet cable to use the USB
modem. If you are connected to the Internet through Raspberry Pi’s
WiFi port, you can disconnect from this connection by bringing the
WiFi interface down with the command ifconfig wlan0 down.
To disconnect your USB modem connection, press ctrl-c
Once you have established the connection, you may consult the full-length

Troubleshooting your Internet Connection
This section will walk you through some troubleshooting steps if your USB
modem did not connect to the Internet. To do this you will need to install a
terminal program to talk to your modem if you do not already have one
installed. Windows users can use Putty and Raspberry PI users can use
Minicom.
If your modem is installed in an embedded Linux environment we
recommend that you install it on a Windows or Linux computer. This will help
you determine if the modem is at fault or if it’s an issue with your embedded
environment.
To use the modem with a terminal program, you will need to know what
COM port the modem is installed on. To determine the COM port, follow the
instructions for your OS below
Windows users: Type Device Manager in the Windows Run box and select
Device Manager. When Device Manager opens, click on ELSx Modem, then
right-click and select Properties. Click on the Modem tab, andthen the COM
port is displayed on this tab.
Raspberry Pi/Linux Users: Assuming you have no other modems installed,
then the modem should be on ttyACM0. To confirm this setting enter
dmesg | fgrep ACM in your terminal window. The modem installs 5 ACM
devices. Use the first device in the list when configuring Minicom.
Now that your terminal is configured, we will walk through some
troubleshooting steps.
Step 1: Confirm that the modem has a SIM correctly installed and the
modem can talk to the SIM. In your terminal window, first enter the
command ATE1 to enable command echo so you can see what you are
typing. Next, enter the command AT+CIMI and press Enter. The modem
should return a 15 digit number. If it returns a 15 digit number continue to
Step 2 below. Otherwise, confirm that you have a known, working SIM card
installed. If you are sure the SIM card is good, it’s possible the problem is
with the modem. See If you Need Help below to contact Zoom support.
Step 2: Check that your APN is configured correctly. Enter the command
AT+CGDCONT? A typical response for the APN would be: CGDCONT=1,
“IPV4V6”, “apn name”, 0 , where apn name is the name of the apn supplied

8
by your provider. If your modem returns ERROR, then the APN is not
configured. To set the APN enter the following commands:
AT+COPS=2 modem will return OK
AT+CGDCONT=1, “IPV4V6”, “apn name”
AT+COPS=0 modem will return OK.
Contact your service provider for the correct APN name. If you can’t get your
APN name from your service provider you can try the following APN names:
AT&T users: m2m.com.attz, or broadband
T-Mobile users: m2mglobal, fast.t-mobile.com, or epc.tmobile.com.
If you are still unable to get online, continue on to step 3.
Step 3: Check the status of your connection. Enter the command AT^SMONI
The response should look something like this:
^SMONI: LTE (or 3G), 4384, 480, -14.0,-76, 310, 410,1B45, 7E65187, 10, 43,
NOCONN
The last parameter indicates the state of the connection. If it says:
CONN - the modem is connected and ready for data.
NOCONN - the modem is registered on the network in idle state. Establish
a connection to begin transferring data.
SEARCH –the modem is searching for a connection. This indicates that
cellular service is not available at your location. You will need to move the
modem to a new location to establish a connection.
LIMSRV –the modem is able to connect to a cellular network but has
limited service available. This indicates that your registration was denied
by the network, so go to Step 4 for more information on debugging this
issue.
Step 4: Confirm that your PDP context is active, and your modem is attached
and registered to the network.
Enter the following commands:
AT+CGACT=1,1 the modem should return OK
AT+CGATT=1 the modem should return OK

9
If either of these commands returns ERROR, enter the command AT+CEER.
This command will return the reason for the error. The full list of errors can
be find in the AT command manual available at
www.zoomtel.com/4630support. The most common errors involve
rejected activation or requested services not subscribed. Possible reasons
for these errors include:
1) Incorrect APN –check with your service provider that the APN configured
in step 2 is correct.
2) The data plan you are subscribed to does not support the type of
connection you are making. If you are subscribed to a LTE only data plan
but are trying to connect on 3G, you could be rejected.
3) You are roaming on another network but your data plan does not allow
roaming. To check if you are roaming, enter the command AT+CREG . If
the modem returns +CREG: 1,5 then the modem is roaming on another
network.
4) Your cellular data account may not have been activated or is currently
suspended. Your service provider may have sent you a SIM and not
activated your account or may have temporarily suspended your
account. Please contact your service provider to confirm the status of
your account.
If none of these steps solves your issue, see If you Need Help below on how
to contact Zoom for further assistance.
