Carefully insert the SIM with the gold contacts facing downward and the notched corner aligned properly. Apply gentle pressure until the SIM clicks into place. Avoid using excessive force, as this can damage both the SIM and the router's slot mechanism.

Configuring APN (Access Point Name) settings represents the next critical step. The APN acts as a gateway between your router and the carrier's network. While many modern routers automatically detect and configure APN settings, manual configuration may be necessary in some cases. You can obtain the correct APN settings from your carrier's website or customer service. Typically, you'll need to access your router's administration interface through a web browser, navigate to the mobile network settings section, and enter the APN information provided by your carrier. Common APN settings for Hong Kong carriers include:

Troubleshooting SIM card issues requires a systematic approach. If your router fails to connect after SIM insertion, begin by verifying that the SIM is properly seated in the 5g router sim card slot. Next, confirm that the SIM is active and has sufficient credit or an active data plan. Restart the router to initiate a fresh connection attempt. If problems persist, try the SIM in another compatible device to determine whether the issue lies with the SIM or the router. Check for firmware updates for your router, as manufacturers frequently release updates that improve compatibility with different carriers. For persistent connection issues, contacting your carrier's support team can help identify whether there are network-side restrictions affecting router usage.
