| If your cellphone provider doesn't use those little simcards, then likely the phones are acivated using a unique ESN number. If someone loses his phone, he would call in to his service provider and the ESN for that phone would be put on a list, so that if anyone called either to report that phone found or try to activate it, the ESN (which the cellphone company asks for when activating) would come up flagged. I know this because I lost my new cellphone less than 10 days after I bought it, and no one reported it back, I had to buy a new one for 400 bones. Boo-urns. |
