Hi, I am hoping someone can advice me please. I took out a sim only contract for my ex. He has now decided to leave me with a pile of debt, took my mobile and is using his sim only contract in my phone. I have rang Virgin to request that the sim be cancelled. Does this take effect immediately. Because until this evening, he has appeared on WhatsApp. Now I'm not sure whether he's blocked me or the cancellation has taken place. Does this mean that he will be unable to make and receive calls and send and receive texts.
