I originally purchased a $40 watch similar to this one from amazon. It was junk! After activating a new line with T-Mobile, didn’t work. Purchased Speedtalk ($10 to get the SIM card, $5/mo after) still didn’t work.
I purchased this one solely based on price and a last attempt before splurging on the Verizon gizmo. It works great outside, which is when we need it!
