How do I know if another device is accessing my data or network or connecting to my sim card some how because people said I texted them when I don't and I can't receive calls or texts from certain places I wish there was a setting to sim if or something to see devices using my sim card or phone number
"people said I texted them when I don't " ask if they are getting legitimate texts and what sort of messages are they getting? if it sounds like phishing text then you could have gotten hacked and need to report to samsung for help, use samsung members app > get help > error report.
"can't receive calls or texts from certain places" check that you have good signal, cause you might just be in a bad reception area.
