How do I insert a SIM card into my Rmo-Nx1?
Use the eject pin included with the device to open the card tray. Ensure that the card is correctly aligned and its notch is first inserted into the card tray, whether using a single or dual-SIM configuration. Be careful not to use cut or modified SIM cards, as these may not be recognized and could damage the card tray. (Page 3)
