SIM connection problem +CGREG: 0,2

[ltschu]

I have a One+ Traccar Edition and using it with the supplied hologram SIM. In the config.h file, I set the APN to hologram:

Code: Select all

// cellular network settings
#define CELL_APN "hologram"

But the device keeps searching for a sim connection:

Code: Select all

Hologram support said:

We dug into the SIM and it appears that it is connected to the Network and opening sessions. The Hologram SIM is working as expected on the Network, allowing the device to open sessions. However, the device is not sending any data through that open session.

What can I do to make it work?

From what we observed, a local sim card is more quickly allowed to register into the network than a roaming hologram sim card. But once it is allowed in, it gets connected fairly quickly every time. This seems to vary among operators though.

Is it normal to wait for several days till the SIM gets allowed to register into the network?

[stanley]

That's not normal. Have you tried with another SIM card?
