@sushil I can confirm Particle has subsequently reintroduced this issue after seemingly fixing it in 1.3.1-rc1. Don’t use 1.5.0. See Stable cellular reconnection newly ruined with Boron 2.0.0-rc1, and perhaps earlier
It’s very frustrating and making me reconsider whether I can stick with Particle. They are such nice people, but their LTE product simply is dysfunctional because it disconnects and then never reconnects, unless if you get extremely lucky (such as I have two stations using 1.3.1-rc1 that have been up for months and are great) (and I have other 1.3.1-rc1s that have never reconnected)
