the Signaling System 7 (SS7) protocol, which is used to by networks worldwide to talk to each other to route calls, and so on.
There are little or no safeguards in place on SS7 once you have access to a cell network operator’s infrastructure. If you can reach the SS7 equipment – either as a corrupt insider or a hacker breaking in from the outside – you can reroute messages and calls as you please. Someone working for, or who has compromised, a telco in Morocco, for instance, can quietly hijack and receive texts destined for subscribers in America.
