You have to call woman twice.
First time: She hears the phone and starts to search for it in her huge, enormous bag, following the sound.
Second time: She has found the phone and she answers.
The time between the first and the second call should be less than a minute.
Otherwise, she will loose the phone in her huge, enormous bag, again.
Unfortunately, this strategy doesn’t apply for other important things, like wallet, keys, sunglasses, pens, papers, cards and all the other stuff that is regular content of huge, enormous bag.
