Phones are keys to information and communications technology, so the answer to the question, yes, phones are included. And phones means all phones, including mobile (cellular), satelitte, landline and others.
Police use mobile phones for the same reason you do; for quick and easy communications with pretty much anyone. The exception to this is in the event of a major disaster that interrupts police and emergency services communications, cell phones are considered a backup for normal police communications. In non-emergency situations, cell phones are not a secure means of communications, and can be eavesdropped upon and used to locate the caller. As such, these are never an official means of first responder and emergency services communications.
The Kyocera phones are manufactured by Kyocera Communications. The phones are made in San Diego, California where the company is headquartered.
