Texts sent to you might be getting trapped in Apples servers, due to an error in Apples iMessage service that the company just acknowledged today. On iOS devices, users can use a service called iMessage to send and receive text messages via Wi-Fi and Apples servers, instead of SMS or MMS messages via phone networks. Many people prefer iMessage to SMS messaging because it does not rack up texting charges, and allows you to continue the same conversation over all your Apple devices.
