How External SIM Card Slots Work

External SIM card slots are typically located on the side or back of the device. They are designed to hold a standard-sized SIM card, which can be inserted or removed using a dedicated key or tool provided with the device.

Once inserted, the SIM card establishes a connection with the device's cellular network, allowing for voice, text, and data communication. External SIM card slots are compatible with all major cellular networks, ensuring seamless connectivity regardless of the carrier.
