Freematics Forum

Hello,
I’m having trouble using a Hologram SIM with the Freematics ONE+ Model B and Freematics ONE+ Model H.
The SIM cards works fine when tested in a phone, but it doesn’t seem to function with the Freematics devices.
Has anyone experienced this issue or have any suggestions on how to fix it?
Thank you!

Network Bands: Ensure your region’s bands match the SIM7070G and Hologram SIM.
APN Setup: Confirm APN is set to hologram:
AT+CGDCONT=1,"IP","hologram"
Automatic Registration: Force auto network selection with:
AT+COPS=0
Signal Check: Run AT+CSQ to check signal strength. Low signal might be the issue.
