This may be why Google can't give a signal booster, since they probably only work with authentic (non MVNO) sims.

Also I checked my Fi bill today, and basically you pay for your data use, apparently down to the 1/100th of a GB. I got an 88 cent refund last month, so they do not round up to the nearest GB for those interested. And with this change in bill pay, I may ditch my T mo mifi and go with a second Fi data only.
