B524's not connecting to cellular network

Connectivity
1

Currently we're trying to claim a bunch of new B524's to our account. This all goes well until the point is reached where the B524 tries to connect to the cloud. At this point, the B524's keep flashing green, indicating it tries to connect, but won't proceed to connect and turn cyan. If we take an older B524 which we activated earlier, it does connect to the network like normal. Then, when we use the web IDE to flash a test sketch (the blink example for instance), it will update once and then become unable to connect to the network like the new B524's.

All our devices are running the 5.8.0 firmware and the problem showed up last weeks. The location of all the devices is in the Netherlands. We also tried making a new account and claiming a new device there to see if it would resolve the issue but this device also keeps flashing green. We're using a particle DEV-board, we confirmed the working of this board using one of the older B524's which does connect to the network.

It starts to feel like something is off with the particle service in the Netherlands but according to the particle website status board, everything should be working as supposed to. We did see that there was a SIM problem last week but it seems to be resolved. Any ideas what can be causing this issue?

Can you grab a couple minutes of logs from Cloud Debug | Troubleshooting | Particle and paste it here? Also, please DM me the DeviceID’s so that I can check on the SIMs.
Do you have a battery connected to the devices? If it’s trying 2G/3G it might be struggling to connect without the battery.

There should be no issues with new SIM activations.

Currently, we are running without battery, it's powered using a 12V supply on the barrel jack connector. We tried switching to a battery but this didn't resolve the issue unfortunately.

For sending the DeviceID's, the forum doesn't seem to allow for DMs, can i transfer them another way?

Here are some minutes of the cloud debug logs:

I was able to grab the ICCID from the logs above.
I can see connections to the carriers, but it seems like power is an issue.
WCDMA indicates 3G is being used - and that does draw a lot of power. 12V is often enough, but a battery is sometimes required depending on the signal.
I do see 4G connections on KPN which were accepted.
I would suggest leaving the device a little bit to give it some time, or adding a battery to help it connect. 10mins allows DeviceOS to reset the modem - which often helps give it the kick it needs.
SIM profile changes can sometimes take a few minutes/attempts before it succeeds.

The SIM is active and has the correct carriers available.

Thanks for checking the SIM and confirming it is active. We now let it hang for around 15 minutes with a battery, monitoring the power draw from the battery while using the device doctor. Below we included the log. What we noted is that when we connect the dev board to the device doctor, it no longer draws power from the battery. When we don't have the device doctor attached, we see a power draw ranging from 0.09A, to 0.35A but no connecting is established.

If we replace the B524 with one of the "older" ones, it connects in <30s.

This part is strange:

Have you tried different antennas on this device(s)?

We first tried it with the included antenna, then switched to an outdoor antenna and lastly a “long range” antenna. I also took one home with me to see if a different cellular tower might change things, but unfortunately without results. The “no carrier” makes me think that the esim is not activated correctly. Given that this log is from a different B524 in the batch, can you maybe confirm if this sim is activated correctly?

Your SIMs are activated - I've seen connection attempts to several carriers, but reports have been coming in about a regional outage that we're following up on. The Particle status page should be updated soon.

According to the Particle status page, the problem has been resolved. For our devices however, the problem seems to persist. We currently have 6 B524's in 3 different kind of boards with 3 different kind of antennas all showing the same problem. Judging from the power consumption, it looks like the boards are trying to connect but still can't establish a connection.

@Support, any update on the situation yet?

We have a solution that's worked for other customers - can you please DM me any devices that you are still having trouble with?
