Straight talk zte z288l hotspot experience

I had the same problem. It needs to be scanned twice, once for paying and once for activation. Stupid system. The easiest solution was to exchange it at Walmart for another one(same price), make sure they scan it twice(UPC and a code at the bottom). Worked fine after that.

I tried to resolve it via Straight Talk and it was a frustrating experience. At least their Customer Service Reps speak good English.
