China exploiting mobile networks to spy on American cellphones

Signaling messages help networks connect calls and track roaming behind the scenes

China may be abusing telecoms' vulnerabilities to spy on Americans’ cellphones through Caribbean phone networks, according to a new report.
“No one in the industry wants the public to know the severity of ongoing surveillance attacks,” Gary Miller, a former tech security executive, told the Guardian in a new report published Tuesday. “I want the public to know about it.”
Miller based his findings on years spent examining threat reports and signaling traffic between foreign and domestic mobile operators. He told the paper that China may have used Caribbean networks to do the job – Barbados, in particular.

Sadly, China has infiltrated Latin American telecommunications one way or another. Huawei provides a large Brazillian telecom with towers and cellphones. I can't guarantee they're not spying on people there.
