I registered my ATT sim card with the HMS phone number and selected a plan.
I’m having trouble with the INTERNET wizard setup. It will say establishing WAN connection and then about 300+ seconds later it will time out and say connection failed.
The WIFI card works great and I’m able to finish the INTERNET setup wizard but not the ATT card.
I’ve tried using Provider: ATT APN: Broadband
Provider: ATT APN: NEXTGENPHONE
ATT APN: m2m.com.attz
None of the above APNs establish a connection
