Where can I find an smartwatch WiFi/Bluetooth tether compatible under $30?

[Android Central Question]

I have searched high, low, in between, over & under for this magical creature and am fearing this unicorn may not exist, HOWEVER, I'm no quitter and will continue to search! I have tried Amazon, eBay & AliExpress. I have purchased & returned so many versions of QW09, DZ09 & who knows wth else over the past year and to no avail - nada. I would think if Bluetooth function is supported that the tethering option would be, too, but apparently that's crazy talk & I've gone mad. Any help anyone could give would be greatly appreciated. I refuse to buy a SIM card and pay a monthly fee for a service my android already provides. Yes, I'm that cheap.

The DZ09 and watches in that class support Bluetooth and mobile data (with a SIM card), but not Wifi. For both BT and WiFi, you're probably going to have to go for an Android watch or an Android Wear watch, and you won't find one for under $30 new. The ZTE ZW10 is available on eBay for $54.52. That's about the cheapest one I've found today.
