If i turn the location services off on my iphone can my iphone still be tracked?

Okay my mom has a tracker on my phone and i don't want her tracking me all the time but its okay sometimes, if i turn the location services of on my iphone will she still be able to track me? And if not will she know she can't track me? Also will i be able to call and text on this setting? Please and thanks peeps!
