Cheetah Smart Plug for Farm Electric Fence

I've a smart power switch was got on amazon must be near 10 years ago needs a sim card and 5 euro top off every 6 months or it won't work the switch cost around 20 euro it's a mighty yoke although I got a second one few years ago for a outside block

hope this is useful to you hard enough to match up with the fence you would need good old coverage on the phone to set it up

The €5 top up is related to whatever phone network you're using, and not the make of switch. Have a look at the different networks websites... Vodafone, Three, Tesco and such. Some of them only need the sim to be topped up every six months to keep it alive. Any of their sims will fit into any make of switch, just like they do in a phone.
