A couple of days ago I got home from school and ended up going back out but only realized I wasn't getting any texts until I got home but only on things that need WiFi, when I went back out I saw that I had no data or signal at all and when I go into my settings it says that I have no SIM Card inserted but I get no notification for it... This problem has really affected me and I even tried factory resetting it but to no avail.. I really want an answer to this and fix it as soon as possible..
