Thank you @bko.
My only addition:
- When using a 3rd party SIM, the default UDP timeout is often 30-120 seconds compared to the Particle SIM’s favourable UDP timeout of 23 minutes, so you can end up using a lot more data.
As I understand it, worst case, staying online with the cloud 24/7 with a 30s keep-alive of 122 bytes every 30 seconds is about 10 MB pr month, compared to about 224kB with the Particle SIM.
