The "Overquota" message is displayed when a campaign is aborted for one of following reasons :
- the universe is using a prepaid mode and credit is sold out
- the universe is using a postpaid mode and the universe has reached the sending treshold

Regarding the postpaid mode, still confuring the campaign the application counts the number of sms to send and those sent in the last 30 days. If the number of message sent is higher than the treshold defined for the universe, sending is aborted and the error message is displayed.
