Your phone service is still suspended if you're only receiving texts/phone calls, but not able to send. The service gal must have failed to do it right.
Basis for this... I never registered one of my number--decided to give it up, since got a better deal with a different number. My unregistered number is still receiving calls and texts (though I've been informed that it will be completely cancelled in November).
You'll most likely have to go back and get somebody to do it again. Sorry.
