I have been receiving call from people saying they received text, or phone call from my number. I do not know these people and I did not send the text (and fid not butt dial anyone either). There is no record of the text in my text log and no record of the alleged calls. My phone never leaves my sight. One caller complaining I text her calling her horrible names happened when I was home alone and my phone was sitting beside me. A friend suggested maybe someone was using Spoof My Text app. How can I stop this?
