I have an RV50X, running Latest code (ALEOS 4.17.1 and Radio 02.33.03) That will suddenly drop connection, report failing to read ICCID, futz around for an hour, reboots, then returns to service. This process takes ~1 hour to an hour and a half. It seems to know the APN it is looking for. The first weird thing after the ‘disconnected’ message seems to say it can’t read the ICCID from the SDK or the sim card. This unit is in a location where the cell signal gets sketchy, but there is a second one 100 feet, of flat open space, or so away and it is not experiencing the issue. That, unto itself, is not really unusual, but it does point more toward the unit having a problem than the Verizon network and it’s singular tower that talks to the site. There have been no events at the site (Lightening, other weather or construction activity to point at. I have replaced the antenna set up with a new one. No change in behavior.
I only have examples of it happening at night.
Do I have a bad RV50X, a bad sim that just gets flaky sometimes, or is this an indication of the Network having an issue and sending the unit into the weeds.
The attached file is an example of what the progression looks like:

Hi @mpinder,
Welcome to our community!
- Please recheck the SIM and make sure it is still functioning properly. Alternatively, try using a different SIM to see if the same issue persists.
In log file, I see RSRQ and SINR values at a poor level, please refer to the following information:
- For a poor RSRQ value:
• A nearby laptop or other electronic equipment may be interfering with the signal. Try moving the AirLink RV50X to a different location.
-
If the SINR value indicates poor throughput:
• Move the antenna away from noisy equipment.
• Move closer to the nearest cell tower line of sight, or further away from the interfering cell tower. -
In case the issue still occurs, please share full log file and template file of the RV50X with me.
***Here are the instructions for obtaining the log file and template file:
-
The configuration template file can be found in ACEmanager → Template. Provide any desired name for the Template Name, and then press Download to retrieve the template file.
-
Obtain the log file:
a. Go to AceManager > Admin > Log > Configure Logging.- Set all log levels to DEFAULT (NOTICE).
- Set Linux Syslog to DISPLAY.
- Then select Apply.
b. Reboot the gateway.
c. Go to Admin → View log → Download Logs.
Thanks,
Thanks for the insights. This unit is VERY remote and is inside the equipment box, so moving it around is not an option. I’m aware of the signal strength issues. We have put both Omni and directional antenna’s on various units that have spent time out there with mixed success.
The snip of log I included shows a complete cycle of events. Is there something specific that is missing that you want to see?
What I was really hoping to gain from posting was an understanding of the messages about the ICCID read failures and to know if the device ‘lost’ it’s ICCID, dropped connection, then failed to read it, or if it lost the connection and, while trying to recover, found that it could not read the ICCID. For that matter, are the ICCID read failure messages just a red herring and it is simply a case of a dropped connection.
Of course, the issue has not repeated since I opened the ticket. I suppose I will just get a new modem out there and replace it if/when it happens again, since the one 100 ft away isn’t exhibiting the problem. I can then futz with it here in the shop.
Thanks again for taking time to reply.

Hi @mpinder,
I see you mentioned that the issue no longer occurs. Did you take any steps to prevent the issue from happening?
If adjusting or changing the SIM helped the RV50 work properly, the issue may not come from RV50. Please kindly recheck the SIM.
“The snip of log I included shows a complete cycle of events. Is there something specific that is missing that you want to see?”
→ I would like you to provide the full log file and template in case the issue persists, even after you’ve changed the SIM and adjusted the RV50X to get a good signal.
If the issue no longer occurs because of the steps you’ve taken, then there’s no need to provide further logs.
Thanks,
Hi Jerdung, The issue seems to have resolved itself. I have done nothing to the device. It is a VERY remote device and a trip to the site requires an action plan, which I did not have. If the issue had persisted, I would have simply swapped the modem out and brought the suspect one back to the office to fiddle with.
My goal here is to understand more about reading the logs myself and to understand what the logfile tells me about what happened. Why, when the signal went sideways and the unit disconnected from the network, did the unit attempt to read the ICCID? what are the conditions where a modem will lose it’s active and stored ICCID simply because it lost the network? what would cause the system to not be able to access the internal memory or issue the AT command after losing signal? These are the kinds of questions I’m hoping to get answered so I understand what is happening should I encounter this again.
You suggested I “Recheck the sim.” What is the process for checking a sim?
I have uploaded the full log as obtained from ALMS and a hopefully sterilized template.

Hi @mpinder,
The “Failed to read ICCID” issue could come from either the ALEOS firmware or the SIM itself. To narrow down the problem, I need you to recheck the SIM you’re using—try inserting it into another device to see if it works properly. This will help ensure that the issue is not coming from the SIM.
In case you switch to another SIM but the issue continues to occur, the problem might be related to the ALEOS firmware.
And to know the exact reason leading to the issue, I need to escalate it to a higher-level support team.
Thanks,
