Was your lover the type of person who loved having the latest and greatest ring tone? Have they suddenly decided that they prefer their ringer not to go off? Have they made it so silent that it doesn’t even vibrate? This is another way to avoid undue attention to the calls a cheater is receiving. By keeping the phone on silent, you won’t notice that they are receiving calls. The flip side of this is that when you call them, you may find that they often don’t pick up immediately. It’s likely that they will call you back a few minutes after you’ve called because they have kept the phone on silent. This works both ways, with your main lover and with the person that you are cheating with. If your significant other has suddenly decided that they don’t like having a ringer on their cell phone, maybe something else is going on.
