Hi
We are using BG96 with Kore roaming SIM
We meet an issue that Registration is denied after working.
BG96 modem is working for about 12 hours.
after 12 hours, suddenly Registration denied happens and then recoverd into Registered, roaming.
I’d like to know why this issue happens, related anything.
