PDP Context APN Configuration
Before a modem can communicate on the cellular network it must have its PDP
context configured with the APN. Devices using Verizon should have the APN
automatically pushed to the device within a few minutes of the first pairing of the
modem and SIM on the network. In the event that this does not occur the APN can be
manually set.
Note
: If the PDP context is in use by an active connection it can not be modified until
the PDP context is deactivated, however if the PDP context is active then this typically
indicates the APN is correctly set. To deactivate a PDP context please see the context
activation command for your modem (AT#SGACT for Telit based modems,
AT+QIACT for Quectel based modems, AT^SICA for Gemalto based modems, and
AT+CGACT for Sierra based modems) or turn off the cellular TX/RX interface by
issuing AT+CFUN=4 on non-Telit based modems modems.

Verizon Cat1+ Devices
Verizon LTE Cat 1 or higher devices should use PDP context 3 for their data
connections and manual APN configuration. Contexts 1, 2, 4, 5, and 6 are used for
other services (SMS, registration, ect…) on Verizon and these PDP contexts should
not be altered. Doing so may cause the modem to fail to register with the network.
To manually set the APN follow these steps.
Get a snapshot of the current PDP context APN configurations prior to editing them in
case an incorrect setting is entered. Type the command:
AT+CGDCONT?
The modem should respond with:
+CGDCONT: 1,"IPV4V6","ims","",0,0,0,0
+CGDCONT: 2,"IPV4V6","vzwadmin","",0,0,0,0
+CGDCONT: 3,"IPV4V6","vzwinternet","",0,0,0,0
+CGDCONT: 4,"IPV4V6","vzwapp","",0,0,0,0
+CGDCONT: 5,"IPV4V6","","",0,0,0,1
+CGDCONT: 6,"IPV4V6","vzwclass6","",0,0,0,0
OK
Issued the following command followed by the enter key to change the APN in the
third PDP context:
AT+CGDCONT=3,"<IPTYPE>","<APN>"
Where
<IPTYPE>
is IP (for IPV4), IPV4V6, or IPV6 and
<APN>
is the APN provided
by your cellular data plan vendor. Most devices should use IPV4V6 for their data plan,
but this will depend on what IP type the cellular data plan is configured to support.
