But South Korean researchers say they've found several weaknesses in VoLTE networks in the U.S. and South Korea.

Their findings, released in a research paper, conclude that it would be possible to spoof phone calls, conduct denial-of-service attacks and overbill customers. They also found it would be possible for a malicious Android app to make secret phone calls in the background due to a flaw in the mobile OS.

The fault also lies in part with operators, which haven't full[y] vetted their infrastructure for security issues. Also, LTE standards have been implemented in different ways by operators, opening up a variety security holes.

"Basically, there are mistakes and things they have overlooked," said Yongdae Kim, a professor with the Korea Advanced Institute of Science and Technology's (KAIST) electrical engineering department, in a phone interview Tuesday.

T-Mobile, Verizon and AT&T were notified of the issues in May, according to an advisory updated on Monday from Carnegie Mellon University's CERT. None of the companies had an immediate comment.
