RE: nRF 91x1 changing APN

Thanks for your quick reply.

After much debugging it turns out that some of our VF SIMs require special setup on the backend, which was not yet done for this SIM. So the nRF9151 connected to the network, but then was rejected by VF. After we completed the setup, the SIM connected with the default APN config (no custom APN config needed).

However, it's good to know that the above mechanism is generally the right way to change the APN, in case we need that in the future.

Thanks,

Hi Terrence,

Looking at PDN library configuration, it does not seem that you omitted any of required Kconfig options (except for optional authentication ones).

Can you provide complete error log?

Best regards,
Dejan
