A7 Thinker GPS Data Problem

Hello guys! I have successfully connected and interfaced Arduino Uno with A7 Thinker device. I use SoftwareSerial and the GPS_TXD is left unconnected, since I execute AT+GPSRD=1, which theoretically forwards all the received GPS NMEA data to the (software) serial channel, which I print to the serial monitor. The SIM AT commands work fine. But when I run AT+GPS=1, AT+GPSRD=1, the output is not right and is the following:

AT+GPS=1

OK
AT+GPSRD=1

OK

and it keeps printing these.

Why it can't receive substantial GPS data? Is it because of the satellite signal? One cause I can think of is the probably limited signal, since I am trying this indoors. Also, I use the in-package-sold GPS antenna (aubree G165: https://www.amazon.com/AuBreey-antenna-NEO-6M-LEA-4S-NEO5M/dp/B072HH36QQ), which is maybe not the ideal one...

What do you think? Anyone who has faced similar issues? Any suggestions/solutions/ideas will be highly appreciated, thank you in advance!

You do not have good satellite reception. Get near a window or go outside.

Take the GPS outdoors.
