My brand new phone sent a text by itself to a non working number in Houston, TX it said "STATMOTN" followed by a long string of letters/numbers. I have no idea what it is or why it did that. I had just begun the activation process and even synced the phone with a brand new email so nothing weird could have transfered from an old account.
STEALTH. Wow. "SHealth" auto corrects to "Stealth." (The dictionary is now assisting dyslexic people.) That feels appropriate in this case considering, if SHealth is the culprit, the app utilizes a creepy way to communicate it's usage data. I hate that app anyways.
