I have about 20-25 SIMs active with Hologram. All have initially registered in the same physical location (West Coast USA) before being sent out around the country. 4 days ago I activated another 3 sim cards and started testing in our 3rd party hardware. These indicate they are registered on the network but have been unable to start a GPRS connection after ~30 re-trys and 3 power cycles.
The hardware and firmware is identical to the other ~20 units that I have tested here. Additionally, I tried a two simcards from a different provider in the same hardware and it was able to get on GPRS. Also I tried a Hologram simcard that was provisioned about 3 months ago and it works fine in this hardware. All 3 succeeded connecting and sending data on the first try.
This leads me to believe there is some issue with allowing data from the newly provisioned sim cards. Possibly data is disabled? I checked my account and I have sufficient funds and the status of all 3 is “LIVE”.
