I have used this for nearly a year now. the messages are a little quirky, but once learned it is fine. One note: While learning, the free service can be quickly exhausted. Carl (Mr. FSTLLC.com) called me when it was low and gave me some extra. I then had him put me on the yearly plan. No hassle with the phone company unless you want it. Carl lets me know yearly and I renew. Nice to set the delay and have the heater turn on at 3AM for a morning flight in the winter.
Excellent product. Call it or text it with free App. Purchase cellular minutes for the device which run about 10 dollars and may be enough for all winter. If you turn on device by calling it, it will be free. If you text, costs about 10 cents per message. The app allows you to turn on outlets independently at different times if needed for the prespecidied time that you may choose. May call or text it to turn it off. Customer service from the company is excellent. Device comes ready to run out of the box. I highly recomnd it. I have owned it for 2 years and it has been priceless!!! My plane loves it!!!
The cell service provider they use has expiration dates on the number of minutes you purchase. $10 worth of minutes should be enough to get me through the winter, however, the minutes will expire before I use all of them. Im stuck paying for minutes I dont need. If you let your service lapse, they will charge you again to restore it. If you want hassle free use of this device, it will cost you $90 per year in reoccurring charges. This device also has issues with the iMessage service if you are an apple user. I have to switch iMessage off to use this device. On the bright side, its nice to turn on my engine heater and cabin heater with a phone call a few hours prior to leaving for the airport. Because of the cell service provider hassle, I would not recommend this item.
Per the manufacturer: U-Phone-iT is limited to 10 Amps (1150 Watts) due to the capacity of the unit's power relays. Also, 1150 Watts serves the majority of preheater applications in General Aviation. You did not supply any details on the aircraft you would be servicing with the device, so I cannot respond directly to your situation.
Most complete Tanis systems (crankcase heater plus cylinder heaters) for a single 6 cylinder engine consume 500-600 total watts, which leaves 500 watts for a cabin heater. If you are servicing a twin with only crankcase heaters you would probably still have enough capacity for a cabin heater.
It is unusual to find 20 amp outlets in a hangar, unless they are there to power special equipment. Most hangar outlets are 15 amp. If you measure the load values of your engine heater and cabin heater you may find they are less than you think.
Per the manufacturer, cell service is not provided outside the U.S for the U phone it Preheated switch.

Per the manufacturer: No, it cannot.
No, it is recommended for hangar / indoor use.
