This is normal messaging during the renewal process. If you have manually topped up your account or have pre-authorized payments you can ignore the message as it's only predictive in case you have not pre arranged a payment of your plan amount.
If renewals are running on time or at least the payment portion your plan about should have already been deducted from your I can't balance or charged to your account credit card on file that is registered for pre-authorized payments.
There are times though that the renewal payment process runs late. Easiest way to check that is to go to your payment history let's see if they have charged for your $10/30 day plan and your data or 100 outgoing minutes amount with today's date. Otherwise you just have to be patient until the payment process occurs.
