I was on an earlier plan that I chose to upgrade. I called US Mobile to upgrade and had excellent customer service from my technical rep named Nobel. He was very patient, listened to my requirements and spoke of a couple plans that met our future needs. Once I decided which plan to upgrade to, he helped me make the changes and "walla", everything started working again and better. Customer service is excellent, the price is just right, and instant delivery to our phones happened immediately. I will continue recommending USMobile to all my friends as one of my friends recommended them to me.
