Answered question
I just subscribed a few days ago, and have applied the 250MB data upgrade. I understand that it will not activate until next period. It shows as pending, and I cannot swap it out now. Will I be able to swap it out for a different upgrade once this upgrade shows as activated?
Yes you'll be able to remove it once its active but that change will take place for the billing period after the one it gets activated in. And then once its active you'll be able to swap it with the one you want. So all your changes should be applied for the billing period after you're next one.
