Because most cheating partners depend on chatting with their lover with their cell phone, using this device is definitely the easiest and quickest way to find any proof. The best and most commonly used technique (because it works very well) to find some sort of evidence is to search your partner’s cell phone and phone bill for numbers which you don’t recognize.

If you’re looking through the phone of the cheating spouse, make sure that you look through the incoming / outgoing call logs, text messages and address book. Looking through all of these for numbers that you don’t recognize will give you plenty of phone numbers that you should note down.
