Cell phone with no serivce can you call 911? - consumer reports magazine phone number

I have a cell phone that it is not now registered and can not service, and I wondered if I can I also call into the 911. I read in Consumer Reports magazine 2 years ago a customer who had written in the diet of consumers back, even if the phone is not registered or not on duty, you can 911th But his cell phone number is not displayed on the screen, even if progress 911th Is that true? Thanks
