An iPhone 5 after having its SIM card removed. (Salvador Rodriguez / Los…)
Some iPhone 5 users are turning to support forums to find a fix for an alleged glitch with the new SIM card that causes the device to suddenly stop working.
The users say they are unable to make calls or connect to a cellular network after the phone abruptly displays a message "No SIM card."
One user has started a thread on the support forum titled "iPhone5 'NO SIM CARD INSTALLED' 'NO SERVICE.'"

"I'm in various places like a restaurant or my home and I get the same issues," she said on the thread. "Why does this happen? I cannot live like this coz I have no landline."
The problem appears to be spread across the three major U.S. networks -- AT&T, Verizon and Sprint.
Users are helping each other find solutions in the forums, with some suggesting the affected owners update their iTunes software to the latest version and re-sync their iPhone 5.
However, the most successful solution appears to be taking the iPhone 5 into a retail store for the network you use and asking workers to replace the SIM card.

"Just an update over on my end," said a user in another thread. "I had the card changed out by AT&T on the 23 and have not had a problem since."
Some users in the thread are speculating that the problem may be related to the iPhone 5 not holding the SIM card in place as securely as it should.
