Using a third party SIM

Hello,
after successfully testing electron with a SIM from Particle, I now want to use a third party SIM. I have modified my code to do the necessary settings for using a third party SIM by setting the credentials.

#include "cellular_hal.h"
STARTUP(cellular_credentials_set("lyca.de", "lyca", "", NULL));

After inserting the SIM card, the device boots up and everything looks fine until it gets to the point where instead of breathing cyan to show it is connected to the cloud, it’s instead blinking cyan. This state of electron blinking cyan is not described in the documentation. In this state nothing can be done.
Do I need to register the third party SIM card online? I have not read that a third party SIM needs to be registered. What am I missing?

Here is a link to see how it blinks

That’s a private video :speak_no_evil:
Any other colors showing, other than cyan?

Greetings from Berlin. Do not forget to remove the SIM pin. Let us know your success. :smile:

Okay, I have made it public. It gets to the point where it flashes cyan and remains there. When breathing cyan it means all is fine

I am using ALDITALK. You do not need to register online.

There is no pin on the SIM. It’s a lyca SIM card. Okay, it means I don’t need to register the SIM. I will figure out what’s going on
