I wouldn't pay a ton for it, just basically happy to just keep my number if I were to change carriers, it's a PIA to notify dozens of contacts about a number being changed !
A business would be a whole different story, I'd consider the value of having an easy to remember nuber like 555-5555, it couldn't hurt !
For personal use, I wouldn't pay much for it, it would be a task just to notify your contacts of the change and you'd for sure forget several people/companies that you don't frequently contact !
I would avoid changing my number unless I moved to a totally different area code, for example if I moved to SC it would be time to lose the CT area code of 203/860, I'm right on the border where 203 starts to turn into 860
If I moved out of state, the number would have to change, many people won't answer a call from an unfamiliar area code and I don't blame them as it almost certainly a garbage call.
867-5309 seems to be a real doable number but you'd probably not want it, even you're a Jennifer, you'd get way too many unwanted calls, it would quickly become a nuisance, perhaps for a business but not your personal phone
It's pretty strange how Tommy Totone was a one hit wonder and the signature tune was a phone number of all things
