So here's the problem: I have a 200 texting plan, and I've used 420 in the first week. At $0.20 a text, $49 is the total. If I upgrade the plan now (to the 1500 texts plan for $15) now, will I have to pay the $15 instead of the $49 for this month, or will the upgrade take effect next month? I know I can call, but the offices are closed, and I'm kinda anxious. Plus, who knows, maybe someone else is wondering the same question.
