Everyone forgets their keys sometimes, but you would never leave the house without your cell phone. It’s just one of those strange quirks we all have these days. The next time you forget your keys, you’ll still be able to get inside thanks to Waleili’s GSM doorbell. When you ring the bell, it calls your phone, at which point you enter your secret code and ta-da, the door is unlocked. Strangely, they make no mention of connecting this device to a landline, so am I to assume that this will need its own SIM card and calling plan? In any case, the pink-and-white plasticky theme will go great with your Barbie dream home. Yup, I’m sold, even if there is no word on price.
