EG800KEU urc +CEREG missing at reboot

Model: EG800K
Version: EG800KEULCR07A03M04

I’m configuring modem with following:
“AT&D2&C1;+CGEREP=1,1”,
“AT+CREG=1;+CGREG=1;+CEREG=1”,
without saving them.

At first modem boot I receive the unsolicited messages:
“+CGEV: EPS PDN ACT 1” and
“+CEREG: 5”

but after a reboot nor detach event nor new unsolicited is received.

Someonelse has same issue or can reply with a tip to have always fresh notify of registration value from modem at every reboot?
