**[blackbow7](https://forum.sierrawireless.com/u/blackbow7) This is another RV50 I ran into that has the same issue. The only difference is that it’s actually detecting the SIM. I already tried resetting both ways, and it’s still giving me the “Network Down” issue. [Jerdung,](https://forum.sierrawireless.com/u/jerdung) thanks for the help. We have decided to move on from using that modem for now. Let me know if you can help with this one. I also attached the logs for the APN ne01.VZWSTATIC since that’s the company-wide one.** ![Screenshot 2026-08-14 121336](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/1/1417326bdd4450d7dd2f22d6267b4523e2ca5830.png) ![Screenshot 2026-08-14 121256](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/5/5bfb29b360c20a5bf83747b2651e2205b1f00fb8.png) ![Screenshot 2026-08-14 121245](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/1/11abd0bd0e004850359c9d626fec471520828924.png) ![Screenshot 2026-08-14 121228](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/a/ab6e4d356e8272b9e33613ffdafcd2f96a3ab9c4.png) ![Screenshot 2026-08-14 121158](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/c/cc6b34d60f0b551f477f87513ba9da7417da69ee.png) ![Screenshot 2026-08-14 121126](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/8/8ad7a22bcab8cd9941739e93375a3b694653ff3f.png) ![Screenshot 2026-08-14 121057](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/8/8f00453fd5ce945bccfead818f6d0b93d969ab0f.png) > **[Attempt 3 - Google Drive](https://drive.google.com/drive/folders/1QM_ED9EjmsxNNr4rzqLtTSuMO4eBRskQ?usp=drive_link)** ---

I understand. I reviewed the screen shots - right! the SIM is recognized, I see the phone number but the signal is -125 which means no signal and I see LTE Band 4. So some progress here … I will review the logs now. No signal could mean different things. I will think and respond again, thank you for this update. ---

I reviewed the log. Looks good and I see the APN in use is ne01.VZWSTATIC. But I see this message three times, Sep 9 00:02:37 warning ALEOS\_CELL\_detectrmdetach: Radio Detach Detected [3] Means that the radio is trying attach to the Verizon network but getting detached. No reason why. Might be best to wait for @jerdung to comment. I will continue to think about this. ---

new question, can you confirm that the APN for SIM card 89148000010351763834 is ne01.VZWSTATIC? Asking to be sure. The symptoms of this problem relate to an APN problem, APN in use does not match the APN provisioned for the SIM card. ---

Hi @mestevez, Based on the log below, I found that your device is ready to connect. However, the RSRQ and RSRP signal levels are currently poor (Current: RSSI=-125, RSRQ=-20, RSRP=-140, SINR=0), leading to your device being unable to connect to the network. Sep 9 00:00:36 notice ALEOS\_CELL\_RadioTask: Radio\_state → RADIO\_STATE\_CARRIER\_SELECTION Sep 9 00:00:36 notice ALEOS\_CELL\_RadioTask: Current COPS user setting: 0 Sep 9 00:00:36 notice ALEOS\_EVENTS\_gnssmgr: 9McEmRmHal: radio module = ALEOS\_RADIO\_MODULE\_MC7354 is active Sep 9 00:00:37 warning ALEOS\_CELL\_detectrmdetach: Radio Detach Detected [1] Sep 9 00:00:37 alert ALEOS\_EVENTS\_gnssmgr: GPS disabled, Assisted Data Retrieval always off Sep 9 00:00:37 notice ALEOS\_CELL\_RadioTask: Current COPS mode: 0 Sep 9 00:00:37 notice ALEOS\_CELL\_RadioTask: Leaving COPS mode as default: automatic Sep 9 00:00:37 notice ALEOS\_CELL\_RadioTask: Radio\_state → RADIO\_STATE\_NOTREADY\_WAIT Next steps: 1. Could you please try moving RV50 to a different location or check the signal strength again at that location. 2. Please ensure that antennas are properly attached to RV50. Two antennas are required when connecting to an LTE network. Thanks, ---

**[blackbow7](https://forum.sierrawireless.com/u/blackbow7), confirming now. I don’t have access to the company account for Verizon, just waiting to hear from my supervisor.** **[jerdung](https://forum.sierrawireless.com/u/jerdung), here is the most recent log for the same modem. I added an extra antenna and moved it somewhere else. I added the same APN in the override section, and after I rebooted and downloaded and reuploaded the template, I got the lights to change green and the network was ready for a couple of seconds until it changed to no service. Let me know what you think from the logs.** [filteredlogs.txt](https://forum.sierrawireless.com/uploads/short-url/onADFgMXI4VvHHWd3me9X8dHruM.txt) (1.1 MB) ---

I understand. I am reviewing the log now ---

I reviewed the log. I see the SIM information and APN information but no signs of a successful connection. The radio is always Detach Detected. This is consistent with the lights changing from green to no service. Me, I would do the following, check with Verizon to be sure this SIM is active and the APN is ne01.vzwstatic try another SIM if you have one? ---

**[blackbow7](https://forum.sierrawireless.com/u/blackbow7)** I tried another SIM, and still the same issue. The SIMs are active with the APN, ---

That was good to confirm to establish a baseline of a known gooding working config. At least the SIM part. What I do not understand is - the antenna are connected but the RSSI=125 which is no signal and you did change the location. Maybe @jerdung can comment. ---

Sorry, guys just got back to the office today from vacation and work in the field. Question, since the modem is an RV50 and not an RV50X, I’m unable to download ALEOS 4.17 and am still stuck on 4.16. When I go to Admin, then Radio Tools, I don’t see that option. ---
