Everyone who knows me, knows I own a lot of handsets. That's purely a "collector cataloging unique phones" thing. But nobody knows, I also own 3 SIM Cards.
I bought them at a charity auction where you could get custom numbers assigned to yourself & the money went to educating homeless kids in a shelter.
One's xxxx180988 & the other one's xxxx210687.
Obviously they're birth dates of me & mine.
One day I will gather enough strength & credibility to gift her, her birth date.
