Review on Solenoid Control Wireless Contact T Mobile by Jimmy Franklin

Used to turn on the aircraft engine heater. Use a basic $5/month SpeedTalk GSM SIM card. Get the AC version if you can. Offers a cleaner installation (no external 12V power supply). You can set the engine heater start time via your mobile phone with the "Delay” option. The heating switches off after the set time. When the heating is switched on, the device sends you a confirmation SMS. and another SMS from the device when it automatically turns off the rear engine heater. Very good. Enjoy. Be sure.
