That is why a text message confirmation is required to get a cell phone's location from https://www.locationsmart.com/try/
For those on T-Mobile, there are privacy settings that can be adjusted here: https://my.t-mobile.com/profile/privacy_notifications/advert... I already had all of them disabled, and I was still able to get the location of my cell phone from LocationSmart.
I chatted with T-Mobile support yesterday to see if I could opt-out of them sharing my data. Not surprisingly, the support agent was less than helpful. "Don't worry, your data is secured"
Are there any US carriers that respect privacy and do not share private information with 3rd parties? Or is that a pipe dream?
