I am trying to connect my fleet of vehicles to a gps tracker. I have tested a hologram SIM in two different GPS306A devices. The device says it has connected to the GSM network but does not respond to any SMS commands, both though the cloud messaging system and by texting the phone number I purchased for the SIM.
The device only responds to specific strings, so I am wondering if there is any format changes to the text message when seeing it through the hologram service.
Any help would be appreciated as I love the hologram service and want to use it for this task!
