I have a significant number of Dash devices available due to a project cancellation (2 years ago!) They were among the final units offered before the Dash was discontinued.
The Dash has been deprecated by Hologram and there is no support, including OTA updates. But, I believe the SIM cards (included) are still viable and the devices should still work on the Hologram platform.
I thought I’d offer them here in case anyone has a legacy app and might be interested. If you are interested, lt me know.
