The CEL-FI GO G51 outperforms its predecessors in terms of power, delivering up to 27dBm compared to 20dBm for the G41 and 16dBm for the G31. With the right setup and antenna configuration, it can achieve download speeds of up to 570Mbps, ensuring reliable connectivity for voice calls and data on any SIM-enabled cellular device.
Why settle for an LTE router that only provides Wi-Fi connectivity when you can enjoy seamless voice calls and data connectivity using your standard phone or SIM-enabled device? Unlike other options, the CEL-FI GO G51 doesn't require any registration or ongoing fees. Simply register
it under your name upon initial setup, and then use it free of charge. The device allows your SIM-enabled device to handle the standard fees you are already billed, making it a cost-effective solution.
That's right, there are absolutely no fees associated with using the CEL-FI GO G51. It functions as a cellular repeater, capturing and amplifying existing cellular signals up to 100dB, thereby improving cellular coverage in areas with limited or no coverage.
