I bought a phone through Genmobile several years ago. This past summer, with no notice to me they cancelled my account. When I tried to renew they sent a new SIM, which would not work (invalid sim). We found that though Genmobile provided the phone when I opened my account, the phone was locked for use with a Sprint sim only. Called Sprint as Genmobile directed, and was told they could not verify ownership of the phone and therefore could not unlock it. So, the phone is basically a brick. After several hours of talking to Gen and Sprint, Genmobile refused to take any responsibility for the error or assist in any meaningful way, as the tech's "supervisor" would not even take the time to discuss the issue with me. I cancelled the account and went elsewhere. When I had the account and it worked the service was spotty, with a lot of dead zones in rural areas.
