Monitor and Control your boat from your cell phone using the SmartSwitch SMS-8

* SIM card or Subscriber Identity Module is a portable memory chip used in some models of cellular telephones. The SIM card makes it easy to switch to a new phone by simply sliding the SIM out of the old phone and into the new one. The SIM holds personal identity information, cell phone number, phone book, text messages and other data. It can be thought of as a mini hard disk that automatically activates the phone (or other device) into which it is inserted. The system uses a SIM card* (in the USA available from AT&T or T-Mobile) to connect your boat to your cell phone.  If you use one of these carriers, add your Yacht-Guard as a new line on a "Family Plan" (about $10 per month) , or use an available low-cost monthly  plan.  Either way, your boat will be able to send you status messages and you will be able to send commands regardless of where you travel.
