Verizon SIM with static APN registers but Verizon SIM with static APN registers but
doesn't connect [SOLVED] doesn't connect [SOLVED]
Problem Problem
A newly activated Verizon SIM with a static APN (e.g. ne01.vzwstatic) is inserted into a 63xx-
series device. The 63xx-series cellular extender is able to detect the SIM and seeing an available
Verizon network, but the 63xx-series device is unable to establish a cellular connection. The
LED behavior on the front of the 63xx-series device will be a flashing white status/LTE LED, and
intermittent 5 bars of signal strength.
Background Background
It can sometimes take longer than the 63xx-series cellular extender anticipates for the Verizon
SIM to finish its registration process on the Verizon network. As a result, the 63xx-seris device
tries establishing a cellular connection before this SIM finishes registering, which results in a
failed connection. The 63xx-series device interprets this failed connection as it not using the
correct APN, so it resorts to its fallback list of APNs to try alternate Verizon APNs with the SIM.
Since the correct APN was already tried, this fallback list of APNs will try APNs that are not
provisioned with the SIM. The result is the 63xx-series device gets stuck trying a fallback list of
APNs, of which none will work with the given SIM.
Solution Solution
Firmware versions 17.8.128.37 or higher resolves the connectivity issues. You can use the
following instructions to upgrade the 63xx-series device to the new 17.8.128.37 firmware:

Manual Solution Manual Solution
Users can lock the 63xx-series cellular extender to keep trying the same APN. This allows the
63xx-series device to retry the same APN that the SIM card is provisioned with. Even if the
63xx-series device cannot establish a cellular connection with the SIM initially, it will keep trying
with the same APN until it connects.
To implement this manual solution, update the configuration profile of the Accelerated 63xx-
series cellular extender with the following configuration changes:
1. In Modem -> APN Modem -> APN , set the appropriate static APN (e.g. ne01.vzwstatic ).
2. Enable the Modem -> APN lock Modem -> APN lock checkbox.
