5G Interface Configuration Guide
The device supports communication via cellular networks after a SIM card is inserted. The module supports 3G/4G/5G networks and dual SIM cards. For Slot 1 (the upper slot), insert the SIM card with the chip facing down and the notch facing inward. For Slot 2 (the lower slot), insert the SIM card with the chip facing up and the notch facing inward.
