Plugging a Micro SIM into the Micro SIM Slot of the
Modem
In order to use your modem, you need a compatible 3GFF SIM card,
which is also called a micro SIM card. You can use a SIM card for Cat M1
and/or Cat NB1 services from AT&T, Verizon and many other service
providers. This modem supports Cat M1/NB1 bands
B1/B2/B3/B4/B5/B8/B12/B13/B18/ B19/B20/B28/B39 (B39 Cat M1 only).
For information on how to order a SIM card from various providers
please see www.zoomtel.com/sim.
Note that Cat M1/NB1 is fairly new technology, and network coverage
varies significantly depending on the service provider and the extent of
its Cat M1 and/or NB1 network deployment.
Verizon users must use a SIM provisioned for CAT M1. SIMs from your
phone or other devices will not work with CAT M1 devices. CAT M1 SIMs
are available from your local Verizon Business sales representative. For
more information visit www.VerizonWireless.com and select Business.

Installing 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. Zoom USB extension adapter Model 98240 can be
purchased from some online retailers.
2From a terminal window on your Raspberry Pi or Linux computer,
enter sudo su to elevate you to root access.

3To enumerate your device, you will need to load the option driver.
To load the option driver, enter the following into the terminal
window:
# modprobe option
#echo 2c7c 0296 > /sys/bus/usb-
serial/drivers/option1/new_id
4Install the ppp package by entering the following command apt-
get install ppp
5Next 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/4650support
6The first script should be named zqdial. If you downloaded the
script, copy it into /etc/ppp/peers
7If you are creating the scrIpt, put the contents below into the
/etc/ppp/peers directory.

9To connect to the Internet, enter the command
pppd file /etc/ppp/peers/zqdial . 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

13
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
Firmware over the Air (FOTA) Updates
Most cellular carriers require having a process in place to update the
software on your ZoomCell modem using FOTA updates. For some
carriers such as Verizon, FOTA updates are necessary to maintain carrier
certifications. The host system for the ZoomCell modem must have the
ability to perform a FOTA update. For more information on FOTA
updates, please see www.zoomtel.com/4650support

Troubleshooting your Internet Connection
This section will walk you through some troubleshooting steps if your
USB modem did not connect to the Internet. If you do not already have a
terminal program installed, you will need to install a terminal program to
talk to your modem. 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 to select
Device Manager. When Device Manager opens, click on Modems, then

15
select Quectel USB Modem,and then right-click and select Properties.
Click on the Modem tab, and then the COM port is displayed on this tab.
Raspberry Pi/Linux Users: Assuming you have no other modems
installed, then the modem will be on ttyUSB3.
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 that
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.

16
Step 2: Check that your APN is configured correctly. Enter the command
AT+QCFG=”apn/display”,1 to enable displaying the APN, then enter
AT+CGDCONT? to display the APN. A typical response for the APN would
be: CGDCONT=1, “IPV4V6”, “apn name”, 0 , where apn name is the
name of the apn supplied 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:
Verizon users: vzwinternet

17
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 to step 3.
Step 3: 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
If the modem does not return OK it will output a CME ERROR code. This
command will return the reason for the error. The full list of errors can
be found in the AT command manual available at
www.zoomtel.com/4650support. The most common errors involve
rejected activation or requested services not subscribed. Possible
reasons for these errors include:

18
1Incorrect APN – check with your service provider that the APN
configured in step 2 is correct.
2You are a Verizon user and do not have a Verizon CAT M1 SIM.
3You are roaming onto another network, but your data plan does
not allow roaming. To check whether you are roaming, enter the
command AT+CREG . If the modem returns +CREG: 1,5 then the
modem is roaming onto another network.
4Your cellular data account may not have been activated or may be
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.
