This has since changed. Cell phone technology has greatly improved.

I have argued that one of the calls from UAL 93 may have been genuine. The plane was very low. The call only lasted 30 seconds. A document from the 9/11 Commission released back in 2011 further supports the idea that it did happen.

However, most of the 9/11 calls are probably dubious. MHG
From what I've read that's not the case at all.

Even back in those days the FCC said the reason aerial cell use was banned was because it could impact ground callers' reliability, not because it wouldn't work in the air (which it did)
