IT is not perfect, but I much prefer it to the old way.
Especially if I have a trip that spans 2 billing periods, but is less than 30 days. I buy it once and am done.
Also, I bought the 120 plan, but they said I can call and move it to 300 if I go over.
Honestly, the unlimited texting is going to be the most useful for me, as it is how I keep in touch with the family.
