RAK 5010 does not connect to cellular network

I have connected RAK 5010 with usb port and using Termite software to read the At commands response. I am getting this response and have tried with hologram, airtel and Jio sim cards but same response. It could not connect to cellular network. This is as described here:

Did i miss any command.

Hi,
RDY means the volgate is not stable, 5010 need at least 3.3V. So please keep the usb volgate stable or connect a chargeable battery.

If you use hologram, just send as below:
at+set_config=cellular:(AT+COPS=?) //search net
at+set_config=cellular:(AT+COPS?) //query your net
at+set_config=cellular:(AT+COPS=1,0,“hologram”,0) //set apn
at+set_config=cellular:(AT+QIACT=1) //active

Hologram will self-adaption the net.

Thanks @nero, it helps . i thought RDY means modem is Ready . Powered it with battery , it does not show RDY message on terminal. and it does connect finally, there is one change though
at+set_config=cellular:(AT+COPS=?) //search net
at+set_config=cellular:(AT+COPS?) //query your net
at+set_config=cellular:(AT+CGDCONT=1,“IP”,“hologram”)
at+set_config=cellular:(AT+QIACT=1) //active

and it works. Thanks
