If I change my plan while my phone is going through another plan will it cancel it until next bill is due
If I understand your question correctly, you want to change the minutes available on your Nationwide plan or you want to switch from a Nationwide plan to a More Everything plan? You can do either one at any time (although if you switch to a More Everything plan, you can't switch back to a Nationwide plan), and you'll be presented with choices to make the change effective now (which shouldn't be done due to pro-ration), to make the change effective at the beginning of the next billing cycle (when you're decreasing your minute allotment on a Nationwide plan or switching to a More Everything plan), or backdating to the beginning of your billing cycle (when you're increasing your minute allotment on a Nationwide plan or switching to a More Everything plan).
If I've misunderstood your question, let me know.
