Seems your environment is not stable, sometimes it can register network, sometimes it cannot

Dear jyijyi,

Thank you for the response.
But in my mobile this SIM card is working fine on the same band (B3), then why in my device the network is not stable?

can you help me to fix it?

From your log about gstatus, i can also see it attached to lte band 3

I don’t know why your board is not stable.
Could it be power issue? Antenna issue?
