Nope, in contrary I will fully believe it. Circuit-switched networks are dead, period. Most "circuit-switched" networks are actually IP networks just with custom FEC'd and prioritised protocols so that there's backwards compatibility. Most Subscriber Authentication systems since UMTS and 3G CDMA (except for super-early deployments, and since they have LTE they would have migrated it if it were the case) have moved into an IP-based system because it's cheaper, and if that's down then everything is down.
