We have created a list of 5G routers with SIM slot that have external 5G antenna connections.  These routers are usually supplied with detachable, 5G blade antennas and these will work very well when the router is in a location with good 5G signal.

If your router location suffers from a poor 5G network signal then these routers will allow the connection of alternative 5G antennas to suit your installation requirements. 

Whether it is installing a high gain, outdoor 5G antenna to provide 5G connectivity for your home or office, or just a dome, puck or adhesive antenna for external mounting on a kiosk or cabinet, these routers are capable of using alternative 5G antennas to ensure a reliable, high speed 5G Internet connection.
