I was completely satisfied with my Virgin Mobile service, and then the company opted for a system update. The company did warn its customers, however, I didn't realize it would have the kind of impact on my service that it has.
My data service speed has been retarded to the point where it is practically useless, and I receive "network error" messages constantly!
Virgin Mobile should take measures to ensure the happiness of current customers, but instead they are worrying about future potential customers. I will no longer refer people to Virgin Mobile for prepaid service, as i myself will be changing companies!
