We have two UEs ASUS ROG and HTC Desire and a Teit Modem Kit - All supports 5G SA band 78
When ASUS ROG and or Telit to register with Free5GC 3.0.6 over E/// B78 radio and seeing error below…
2022-09-21T10:25:42-06:00 [WARN][AMF][NAS][AMF_UE_NGAP_ID:16] NAS MAC verification failed(received: 0x4ca9f0f0, expected: 0x00000000)

But
there are no registration issues with HTC Desire and everything works… We can run youtube and can browse web etc but after 15 minutes it drops pdu session…
Please note all above devices works perfect with another 5G SA Core…
Thoughts/Suggestions…
