Did you schedule a plan change? It sounds like you added funds to your account balance thinking you were purchasing the new plan and then your renewal occurred deducting what was your current plans cost.
When is your next renewal? A little less than 30 days from now? Schedule a plan change on next renewal.....Choose the new plan you want then pick change on next renewal. Don't pick change immediately as your plan will change right now and you don't get any money back or credit for the unused portion.
Top up the difference missing in your balance to cover the new plan cost sometime between now and renewal only to avoid a possible autopay failure as this sometimes happens when switching to a higher priced plan and relying on autopay to pay for it.
Do you need the additional data that comes with the new plan? If you don't....how much calling to the US do you think you will do?:The $15/1000 US minutes calling add on is nearly 17 hours of talk time. Add on minutes roll over every 30 days until you use all of them so if you need 5 hours a month to call the US that is the equivalent cost of $4.50 leaving 700 minutes for the following month and so on..... think about how much you will call and if you need the data as it might be cheaper just to buy the add on as a one time purchase that does not expire and have it sit on your account to use as needed.
