How to set up parent control on the Cudy router 4G LTE LT400??
@Dear Tim,
We don’t sell SIM card for the router. You need to apply a SIM card from your local ISP. It is the similar as the SIM card of your phone.
“Where is sim card 5G ? nothing in box 5gNR AX3000 WIFI 6ROUTER”

Dear Customer,
Thank you for contacting Cudy support team. Our technical support has contacted you via email. Please check.
""Just purchased a Cudy AC1200 Mbps Dual Band 4G LTE Router, inserted Sim, turned on set up and all worked ok.
Tested using mobile phone, then when trying to connect a laptop would only connect to non 5g, and then stopped connecting altogether.
Have reset and there is no internet connection, have tried different Sim and still no internet connection.
The router just won’t connect anymore. Any steps I can take or does it need returning?
