In a perfect environment with full support from the cellular service provider utilizing low frequency digital 850 or 900 MHz service, it is possible, but the real-world applications are typically under a 40 km/25-mile range due to timing issues which normally hand off phones from cell tower to cell tower. Above 40 km you will need the support of the cellular service provider to expand this timing on the antenna sector you plan to use. Other factors such as terrain play important roles in the signal arriving at a stable and reliable level.
