the SIM was installed in the LTE eHWIC without this network process completed and the ISR powered
down. If the latter, there are two ways to address the problem: 1) Power down the ISR, remove the SIM,
and then put the SIM into another LTE device (Novatel Mifi hotspot, LTE eHWIC, etc.). When that device
connects, reinsert the SIM into the LTE eHWIC, connect the antennas, power up, and wait 10 minutes. 2)
Use the local APN change command in step 9. The Cisco IOS Software command show cellular 0/x/0
profile displays the APN (show cellular 0 profile for the 819).

If the LTE connection becomes active but then begins to flap (repeats going down and up periodically,
usually every 5 to 60 seconds), a configuration problem must be resolved.
a.
This behavior can be caused by a network disconnect due to IP source address violations. It is
resolved by reconfiguring the traffic to be tunneled, NAT, or access control lists (ACLs) so that no
traffic is routed without being tunneled or subjected to NAT. If you cannot determine which IP
address is causing the IP source violation, contact the Verizon Wireless Enterprise Help Desk
(800 922-0204) and ask them to trace the call and report the IP address that is causing the
problem. Then correct or add NAT, ACL, or VPN to stop any packets without the LTE eHWIC IP
address from leaking out.

The data APN for Verizon Internet with Static IP LTE service is different than for Internet/Dynamic. The APN
depends on the U.S. region, and should be provided by your Verizon representative. If the value is incorrect
(IOS command show cellular 0/x/0 profile displays the APN, show cellular 0 profile for the 819), OTA-DM
has not changed it automatically. Change the value manually via the appropriate 1-line IOS command:
a.
For 15.2(4)M3 or M4 (ISR) or 15.3(1)T1 (CGR), below is an enable-mode command example:
cellular 0/0/0 lte profile create 1 ne01.VZWSTATIC (
Note that the Data APN is profile 1)
b.
For IOS 15.3(3)M2 and later, additional APNs have been exposed (IMS, admin), so the profile
number has been changed from 1 to 3. Below is an example:
cellular 0/0/0 lte profile create 3 ne01.VZWSTATIC (
Note that the Data APN is profile 3)
c.
The preceding methods also are applicable for Verizon MPN without DMNR service
