I am working with a group of different 2G devices, all GPS trackers of various manufacturers. Each of these DOES currently work with the TING.com service just fine.
With Hologram, I cannot get connectivity at all. The dashboard shows no service, and assigning a phone number and sending SMS does not ever get received by the devices. I have confirmed SMS is not received via serial debug on one of the devices.
Is there a different SIM card I should order for 2G devices?
