I currently have a 40GB + grow package. I wish to change it to unlimited package as mentioned in data volume optimization menu. If I choose unlimited package, will I pay for new package or both packages? What will happen to the minimum contract duration? Will two year contract be continued from the last package or again start from date of getting new package?
