A method of treating a subject includes providing a mobile telecommunications device including a processor, a transceiver coupled to the processor including a transmitter for generating pulsed electrical signals adapted to be coupled to an antenna, at least one memory device accessible by the processor. The mobile telecommunications device is positioned proximate to the subject. Pulsed electrical signals are begun to be generated to cause the transmitter to drive the antenna, wherein the antenna in response to the pulsed electrical signals emits a pulsed electromagnetic field (PEMF) that reaches the subject to provide treatment.
