New One+ is not registering on my cell network +CPSI: NO SERVICE,Online

[Angry Owlbear]

I've unpacked my one+ and have started setting it up. I've downloaded the latest build of stanleyhuangyc/Freematics/tree/master/firmware_v5/telelogger and I've compiled it with Freematics Builder. I'm using Tello and have set the APN to 'wholesale'. When booting, I see that it detects the SIM card but fails to register, giving me an error +CPSI: NO SERVICE,Online.

I have tried swapping the direction of the SIM card in case I had it wrong but, as you can see in the bottom of the output, I then get NO SIM CARD. So it seems my SIM but can't register on the network. I have tried using this SIM in another device and it successfully joins using the same APN.

Tello uses B2/B4/B12 which are all supported by SIM7600A-H.
Is the APN correct? If unsure, try leaving APN blank (default from network).

I have the same problem. I have tried different sim cards but with no result. They all stuck in activating! I have tested the sim with other tracking device and it works!

I have changed the APN via app before and now when I am trying to remove it via APP (as your suggestion) it does not allow it.
I can only rename the APN via app.
How to remove the APN if it was set from the app?

Thank you.

You are getting the same NO SERVICE response?

You can try these steps: verify SIM functionality and APN settings, check SIM card placement, update firmware, and reset network settings. Retro Bowl

If IP is obtained, this is not a hardware issue. Check if the SIM card has got enough balance.
