345 and the one-ring scam
Because 345 looks like a US area code, it is a favourite of "one-ring" (wangiri) scams: the phone rings once, you call back, and the call is billed as international — sometimes with premium per-minute charges that go to the scammer.
If you do not know anyone in the Cayman Islands, do not call back a missed 345 call. Look the number up first, and ask your carrier to block outgoing international calls if you never make them.
