The affordable, customizable plans that can be adapted to monthly needs, the near-instant customer service that always gets the problem solved, and the variety of equipment available directly through the company means I will be sticking with US Mobile for a long time to come. I had trouble with one contact not working, the 'blacklist' option was explained to me and how easy it is to accidently set it and how easy it is to undo it. I couldn't get my voicemails because of a fault in a phone purchased elsewhere, I was walked through in real time by the representative in resetting the voicemail options and another way to listen to them. When my needs for text and voice change, it is so simple to alter the plan for the next month, for less than pennies a day.
