so I have a new iphone (SE?) that I recently upgraded and its connected to a family members account and her LTE data works just fine when she turns it on but mine doesn't do that at all. I have gone to settings and cellular data is on, lte is on but they don't work? like in the corner where the carrier is shown it doesn't say LTE. I'm not connected to wifi at the moment and it still doesn't work. does anyone have a solution?
