Calling back is an international call
Calls and texts to 664 numbers are billed at international rates — often much higher than calls to the US or Canada, and usually not covered by plans that include North American calling. If you missed a call from a 664 number you don't know, don't call back.
The US Federal Trade Commission has warned about “one-ring” scams using this area code: the phone rings once so you call back, and the call is billed per minute on top of an international rate. If you don't know anyone in Montserrat, don't call back. Read the FTC alert

- Who is calling me from a 664 number?
