👍 As a quick solution. More generally we should probably add some define easily accessible everywhere (e.g. in hal_platform_config.h ?)

I have noticed that in some cases that even connecting back from Particle.disconnect() was taking longer than expected - for example, this build and src code.
This is probably because it's 2G.

@avtolstoy Set a HAL_PLATFORM_CELLULAR_CONN_TIMEOUT value in hal_platform.h
