Huh? The phone company has _always_ recycled phone numbers. The only time you got a new one if you're entering a new exchange.
It's certainly true that there aren't enough numbers to go around. Unlike a home phone which tends to be more permanent, cell phone accounts can be opened and closed repeatedly.
However, I do feel 30 days is not enough delay time. Because one has to pay for incoming calls, wrong numbers can be costly. Accordingly, I think a number should lay dormant at least for a year. I also think they should give 90 days free referral just like a land line phone.
[some techie suprised phone numbers don't last forever.]Obviously when any business closes out an account, it must close out everything. This isn't an issue of recycling the number, but rather failing to close out the account and reset all defaults. Presumably the man didn't want text messaging so that should've been turned off. All those text calls would've been rejected. End of trouble.
It appears companies that use new technologies are so quick to start up and get running that they don't bother to build proper administrative systems. So garbage like this happens. What is insulting is that the companies deny responsibility even though it was their inter-billing arrangements that made it all possible in the first place. You can be sure Sprint was nicely compensated for its relationship with the other outfit.
Imagine you sit down at a restaurant and your check includes food ordered by the previous customer. No one in their right mind would tolerate that. But apparently when it comes to technology that kind of business practice is perfectly ok.
