Multiple APN setting on nrf9160

[Aswin P V]

Hi,

Is it possible to set multiple APNs in nrf9160 and with fallbacks to next APN if one not working?

Suppose if we set 2 APNs at CID=0 and CID =1 positions using AT+CGDCONT, whether device will connect to second network APN if first is not available?

We mistakenly set network provider APN at CID = 1 instead of CID = 0, device was not connecting to the network in that case. ( CID = 0 not set)

When we set at CID=0, it started connecting to network.

Please help in understanding what will be the expected behaviour if set multiple APNs?

Thanks in advance,

Aswin

Hi,

What network operator are you using (and where)?

Are you using LTE-M or NB-IoT?

I have asked the modem team about the details, and according to them, the exact behavior is dependent on the network.

But it will not function as a "fallback". CID 0 is used during the attach, while CID 1 (or others) can be used to open additional PDN connections after the initial attach. However, if this is allowed, or what they can be used for depends on the network.

CID 0 is activated automatically, but the rest must be activated manually after the attach.

Best regards,

Didrik
