The router will not eject my Express Card
On some ExpressCard format cellular modems, the SIM slot position may cause the card to become stuck in the router.
The method to remove the modem once it is stuck is to place piece of paper or business card over the modem, as shown in Figure 1. Then the modem can be easily removed.
A method to prevent the modem from getting stuck is to place a strip of tape over the SIM card slot, as shown in Figure 2.
