I'll be the first one to admit I know next to nothing about the way the cellular phone system works. Maybe someone here does.

It used to be when texting a radio station, they'd give out a special number. You may remember CFRB's was "7-1010," which they promoted incessantly on air. AM 640 had one of its own, too, as did other outlets. But not anymore. Now if you want to text a station, you're asked to just use the regular call-in number. 

Maybe it's just a cost saving gesture. But doesn't someone dialing a number to send a text wind up tying up that number for callers who want to go on air and just make it harder for listeners to get through? And do they still have special cell phone numbers to report traffic issues?

I admit I don't know how these systems work, but it seems to me they're putting a lot more stress on the available lines then they have to. Is everyone abandoning these in favour of one central phone number?
