Quectel MC60CA disconnets from network moments after conencting

Hi,

I have a Quetel MC60CA module and I am trying to connect to network,
After these commands:
AT+CPIN=7066\r\n
AT+QICSGP=1,“internet.telekom”\r\n

I check the conenction staus with AT+QSPN?\r\n every 1s.
After ~ 3s the AT+QSPN?\r\n returns, that the module is not conencted to the network?

Did I miss something?
Any help is much appreciated!!

SOLVED!

I had current supply issues.
