Sprint Search is designed to answer questions that are worded in plain,
conventional English, just as you would ask them to another person.
Try checking your spelling and grammar to help get the most accurate results.
Correct capitalization is not required, but can sometimes help to locate names and acronyms.
Like others, I have blocked texts through my preference and they are still coming through as text messages.
