Several of our RV50x are being plagued with issues not having an APN set. The APN is not being assigned automatically and we are unable to set it manually. We receive the following messages in the system log.

Has this issue happened before? Or is this the first time?
How did you set up the APN for your AirLink RV50X? via Web GUI or AT command? Please share with me the screenshot.
I see that your APN is not normal, please make sure it is supported. If you are using normal Verizon SIM, please try “VZWINTERNET” APN then recheck whether the issue is resolved
If you have done the above items but the issue still happens. Please try another SIM card. Do the issue still happens in this case?
Hi there, it looks like my original reply got cut off when I replied by email a couple of days ago. Here’s that reply again, submitted through your website.
Here’s the firmware info on one of the problem devices:
ALEOS Software Version: 4.15.3
ALEOS Build number: 003
Device Model: RV50X
Radio Module Type: MC7455
Radio Module Identifier: VERIZON
Radio Firmware Version: SWI9X30C_02.33.03.00 r8209 CARMD-EV-FRMWR2 2019/08/28 20:59:30
This is the first time this has happened, however, out of a batch of six modems which were all operating normally for about a month, three of them are now exhibiting the behavior with the APN not being assigned. This started after a period of intermittent power outages. When we restored reliable power the devices appeared to be working normally (all lights were green) but they no longer had an APN or static IP address.
The APN was not assigned by us. Once the devices were provisioned on Verizon’s network the APN (along with a static IP address) was automatically assigned. In troubleshooting See below for the screenshot of the APN being blank.
mw01.VZWSTATIC is the standard APN for any of our Verizon devices that have a static IP address. The APN VZWINTERNET is for devices with dynamic IPs.
I swapped SIMs between a working modem and a non-working modem. The working modem works regardless of which SIM. The non-working modem doesn’t work, regardless of which SIM.
Please remove the APN “mw01.VZWSTATIC” in the APN Override tab in the screenshot you attached then click Apply-> Reboot. Do the issue still happens in this case?
If the issue still happens, please share with me screenshot of the Cellular tab by access to ACEmanager->Status->Cellular.
I’m having a similar problem with my RV50X. The modem isn’t recognizing the APN from my SIM card and my WAN IP is continuously changing instead of the static IP that it has assigned. I was able to correct this issue a few months ago by upgrading the firmware and radio firmware; I forget what version it was previously but when I uploaded ALEOS 4.16.0 and Radio Firmware SWI9ZX30C_02.33.03.00 r8209 that seemed to resolve the problem and the APN was found and the WAN IP was what it should be.
I saw there was a new firmware version (4.17.0) available so I updated it again but this time it did not correct the problem. I’ve verified the SIM is good because when I load it into another modem the APN is found and my WAN IP is up and running. Any ideas on a resolution would be appreciated.
According to the image you provided, the device is currently set to use the Active SIM in Slot 2, but you are attempting to configure it on SIM Slot 1. Please remove it from Slot 2 and insert it into Slot 1 to see if the issue persists.
I have downgraded to 4.16 and still have the same issue with the APN not being found and my WAN IP is constantly changing. As I stated earlier when I originally had this issue, upgrading to 4.16 from 4.15 seemed to work for a couple months but then it stopped.
I looked at the suggested topic and have tried using an Override APN for both SIM slots 1 and 2 and the static WAN IP from the SIM card is not being recognized. The first screenshot shows the problem modem with the APN in Use “Not Found” and the Override APN manually input. The second screenshot is with the same SIM card in another modem (ALEOS v. 4.15.0) and APN is recognized and all is working fine.
I am having the same issue with 1 of 4 modems of a group that were purchased together. I have run through the same troubleshooting and testing as described throughout this thread with no resolution. Has anyone made progress and resolved the issue? I am at a loss, even a factory reset does not get the modem in a state where it picks up the APN from the SIM or allows me to manually set the APN.
Thought I might add an update since I first posted about this issue. I ended up sending the modems back to Sierra Wireless to diagnose and repair. It seems that all they did was reset them to factory settings and install the newest firmware. After this the problem persisted so these modems have been serving as paperweights ever since.
Some questions for other who are experiencing the APN issue. Are your modems showing all green lights as if the device is connected to the network and functioning normally?
If you look at the system log are you getting the same set of messages that I received?

Yes, my modem is showing network connection, good signal strength and power in the led light displays. My logs are showing the same as yours. Each time I reset or try making any changes you can see the WAN IP changes. My guess is that the APN isn’t allowing my SIM WAN IP to be recognized and set but I have a feeling I may have to get a new modem because the SIM works fine in other modems I have, just not this one.

Do other RV50X modems that are working fine have the same ALEOS version and radio module firmware as the modem experiencing the problem?
If the issue persists on one RV50X despite having the same ALEOS version, radio module firmware, and configuration as other functioning modems, it is likely a specific issue with that particular RV50X unit.
In this case, it is recommended to send an email to technical support at support@sierrawireless.com for assistance.
We’re seeing the same issue on a number of our devices (at least 7 so far) - they had been working fine with static IPs, and then stopped being able to find the APN - with no changes made to the devices. Our logs look the same as yours except we’re using ne01.VZWSTATIC. We’re getting good signal, the devices are just unable to connect properly.
I tried updating firmware, reset the device, nothing has worked so far. Can swap SIMs between devices, and the affected modems are getting random IPs and are not able to connect to the internet, but if we put the same SIM into an unaffected device it functions as expected - it finds the APN and we get the expected static IP. We are running power management of the device so that they are turned off most of the time (on for about 5 minutes every hour.)
