Automatically detect APN for external SIM

Hi,

Why can’t the external SIM mode autodetect the APN? This keeps causing issues for me, since I have to set up the external SIM onshore, but the network isn’t available before offshore. So I can’t test, and apparently the provider doesn’t always provide the right APN or they have several different options.

Hi @gauteh,

My understanding is that the APNs are not stored in the SIMs themselves, so it’s not even technically possible to auto-detect them (although I can definitely see why that would be useful).

I’m not sure if you’ve tried this or not, but you can use the dual-primary-secondary option of the card.wireless API to tell the Notecard to start with the primary SIM and then fallback to the secondary (external) SIM.

Hi,

If I put this sim in a regular phone it figures out the configuration itself, so it must be possible. I think this is what happens with all sims? I’ve never had to manually configure an apn.

I do use the dual method, but this is an area and network that does not work with the onboard sim.

Thanks, Gaute
