With Fieldbook F1, Logic Instrument is launching a robust dual-SIM phablet onto the market. It weighs 270 g and offers the option of using two different SIM cards simultaneously, which saves switching back and forth from private to work phone and prevents data security problems. Continuous network coverage with two SIM cards from different providers is also possible. A built-in 4G LTE module and Bluetooth 4.0 ensure wireless data processing. A WLAN interface with AccessPoint function and RFID NFC are also on board. The phablet works at temperatures from -10 to +55 °C. Android 5.0 serves as the operating system for the IP68-certified device. It is equipped with an octa-core processor and 2 Gbytes of RAM. For large data volumes, the phablet is equipped with a built-in card reader that can work with SD cards up to 2 Tbyte, a mini USB port and an internal memory of 16 Gbyte.
