I built several devices for a client and tested them in Boston before shipping them out. Upon startup in their new location (Mexico City), they appear to be functioning fine (all are breathing cyan), but they haven’t completed a handshake with the particle.io server and I cannot communicate with them. The SIM and module are the same since they should work in both locations - is there something I’m missing? Is this an issue with the device or the cell comms? Is there anything I can do to debug further?
Hi,
Are you using Particle SIMs, or 3rd party ones?
cheers,

These are all Particle SIM cards. They all eventually came online, but some took up to 4 days after breathing cyan…
