Hi
Does the keepAlive time depend on the APN or the cellular network operator? How can I know the exact amount?

Yes, it depends on your carrier and SIM card. It’s not necessary to set it when using the Particle SIM card, but for 3rd-party SIM cards you will almost certainly need to set it.
It’s often necessary to find the value experimentally; the instructions are here.
