Why Am I Billed on a Pay-per-Use Basis After I Purchased an SMS Package?

The possible causes are as follows:

• Before a package takes effect, the outstanding balance and pay-per-use fees generated under the account cannot be offset by the package quota.
• The package does not take effect in time. Log in to the Message & SMS console, choose Billing > My Packages > Resource Packages and check whether the package has taken effect. If you renew a purchased SMS package, the effective time of the renewed SMS package will be postponed to the time when the previous package expires.
• If the package quota has been used up, the usage exceeding the quota will be charged on a pay-per-use basis. For details, see How Can I View the Remaining Quota of the SMS Package?.
• Currently, only SMS packages for sending SMSs to the following countries are available: Indonesia, Thailand, India, and Philippines. SMSs sent to countries that are not included in the package are charged on a pay-per-use basis.
• Check whether your SMS package belongs to Message & SMS.
