You know, I have to agree with this. The entire Nexus 5 launch with Google play was a fiasco. Representatives were not trained, nobody knew how to order a SIM card, and to this day Sprint is also unable to recognize the handset attached to my account.
Maybe there is a technical hurdle within the system that prevents this but i am more apt to believe that someone at Sprint is dropping the ball and not following through to make these things work as it should.
We should be able to activate a t-mobile nexus5 on our accounts, the Sprint website should recognize our Phones, and we should be able to change optional services. I'm guessing the only reason why we can't is because whomever is in charge of these things is not doing there job.
