GPS Kid Tracker Smart Wristwatch Scam Internet

I purchased one of their smart watches for my daughter as a christmas gift. I ordered early, knowing that it could take a while, and it did take a month, but still arrived in time for christmas. First, they failed to mention that it required a sim card, so that was a let-down since the gift couldn't be used. Then when I inquired about what type of card to purchase or where to purchase it from, they directed me to a random blog (which took them over a month to respond). Once I read the blog, I purchased the sim card suggested only to find out that this card is not compatible at all. I tried downloading the app but none of it makes any sense. The words are english but they don't use sentences that make any sense whatsoever. Complete waste of money!!!
