GL-X300B (Collie) SIM Card not registered

Apfelsafft · 2023-03-27T17:39:03.230Z

Hello,
I just bought a GL-X300B (Collie) and don’t get any mobile data connection.
The 3G/4G modemshows the carrier but keeps saying “SIM card cannot be registered”.

I searched the forum and tried the following thing:

AT+QPRTPARA=3 command on /dev/ttyUSB2
QMI mode on /dev/cdc-wdm0
PPPD Dial on /dev/ttyUSB3
tried several options on APN settings as I found for O2-de (Auth = PAP)
tried 2 more SIM cards from different carrier (only one with PIN which was requested by the modem)
tried all 3 sim cards on mobile phones to clarify that they work and do not need PINs.
the SIM card was also tested on a HUAWEI 4G router and works flawlessly

Firmware is 3.215
Antennas are connected.

This is a brand new router. Could it be defective? Or am I just doing something wrong?

Best regards,
René

Which carrier does your SIM card belong to?

Apfelsafft · 2023-03-28T10:57:53.241Z

The one I’d like to use belongs to german O2-de.
The other two I tried are Vodafone and Congstar (telekom carrier, I guess)

Very strange question, I suspect the antenna is not connected properly, can you open the metal shell to see the antenna connection? It is best to take a picture of the connection between the antenna and the modem.

Thanks for the feedback.
I tried to open the shell but the screws are really tight and two didn’t move.
As I am on tour right now I will try it back at home with some better tools.

However, as you asked about the Antennas, I noticed that the external connectors are quite loose. They can be easily disconnected by slightly pulling the cable. Only the GPS and one 2.4GHz connector feel more “secure”.
Is there something I can do?

Hi,
I have similar problem.
Gl-X3000NR always says "SIM card not registered".
I've tried 5 sim cards from different operators.
APN for all are correct.
It can find all towers with their Info. I even know which towers belong to my different sim cards. It just doesn't work.
My all sim cards work on different routers and phones of my family, friends and mine without any problem.
I thought maybe IMEI of this device is restricted. So I contacted the operators and even national security but they answered me your device IMEI code is not restricted and the problem should be in your device.
Even I had doubt so I changed IMEI to my different devices but still no chance. This device always says "sim card not registered" for 4 months. I'm very disappointed
and I feel just lost my money by buying this pretty device.
If anyone knows any solution, will be much appreciated. Thanks you.
