Electron + Particle SIM + U260/U270 confusion in AU = unable to activate

[chuank]

Thanks for the heads up, I missed that bit regarding the APN setting. I'll try what's discussed in this post to set the APN details for my Optus SIM:

How to set 3rd party credentials for the Cellular network? [SOLVED]

I see that you have a solution: https://docs.particle.io/reference/firmware/electron/#setcredentials- Whether this solution can be used with WebIDE? If once when you configure whether you can program Online?

Sending another email to hello and see if this u260/u270 case for earlier au adopters can be looked into with this new information. Thanks again for chipping in!
