I received my two SIM cards today and tried them in the various old phones I had laying about. They didn't work in my oldest smart phones, a pair of Motorola XT912 "Razr", which is odd, since I've used it on AT&T before with a GoPhone SIM.
Anyway, one card into a LG G2, the other card into an AT&T G-Pad 7 (also LG). The G2 is an unlocked Verizon phone, but with a "world phone" feature so it has some GSM support, on speed test I got 3mbps download and 1mbps upload. On the tablet, I got 10mbps download and 3mbps upload (AT&T 4G LTE service)
Time will tell on how useful the service is, but for the price, I'm willing to give it a shot.
