My guess is you need to update the modem firmware.  
Directions [here.](https://docs.gl-inet.com/router/en/4/tutorials/upgrade_quectel_module_software/)  
Various firmware releases [here](https://github.com/4IceG/RM520N-GL?tab=readme-ov-file#firmware)  
I am in the US. Running the file dated 02/01/24 right now. This got me to connecting to 5G on Verizon with stability. These routers seem to be shipping with very old modem firmware.
