what does sent as text message mean that the message you attempted to send wasn't delivered through your regular data connection or internet service, but rather as a traditional text message using your cellular network. This distinction is important in the context of messaging options.

Unlike internet-based messaging services like iMessage, WhatsApp, or Facebook Messenger, which rely on data or Wi-Fi connections, sending a text message uses the Short Message Service (SMS) or Multimedia Messaging Service (MMS) protocols over your mobile carrier's network. 'Sent as text message' indicates that the recipient's device might not have an active data connection, or the messaging platform you're using couldn't establish a data connection at that moment.

While text messages are reliable and can be sent to virtually any mobile device, they may lack the multimedia features of internet-based messaging apps. Understanding this notification helps users grasp why a message may have been sent differently and prompts consideration of alternative communication methods if immediate delivery is crucial.
