Set the APN to a blank string and set APN Number = 3.
Configure the PocketPORT before inserting the USB modem. After writing the configuration parameters to persistent memory, power off the PocketPORT, insert the USB modem and power the PocketPORT back on.

Signal strength will not display until the USB Modem Port has
been set to ttyACM0 and the configuration has been saved
and the PocketPORT restarted.
This modem is very sensitive to positioning for achieving optimal
signal strength and throughput performance.
For more reliable operation, lock the UML290 into either 3G or 4G mode.

By default, the Verizon Wireless LTE network provides NAT'ed
private IP addresses and blocks inbound initiated connections
from the Internet to remote devices attached to the PocketPORT.
Use two PocketPORTs in Virtual Cable Mode or request a static public IP address from Verizon to overcome this limitation.
*** If you have upgraded the UML290's firmware to B333F.230 (MR2)
or later, you must have firmware version 1.4 or later installed on
the PocketPORT.
