If you change immediately. Should be instantly. You're charged right away and no refunds on unused days from old plan. Step one add money to your account. Step two do the plan change.
Click change plan then pick a new plan.
You have two options.
1= Change now - (It will say top up now if you don't have funds to cover new plan).
Not advised to pick this one.You are charged right away for new plan and no refund on unused days from old plan.
2= Change at next renewal. The choice most want to pick. Your new plan you pick will be scheduled to start at your next payment due date and you will be charged then for the plan
