Nobody knows what these calls and callers are up to, but when you get a call from a strange number, chances are they are trying to trick you into disclosing personal information that would help them steal money from your account or others.
However, just because you get calls from foreign numbers does not imply that the call originated in that country. WhatsApp enables encryption for calls and texts, making it difficult to track the individual, and it appears that hackers are taking advantage of this to swindle customers.
if you get a call on WhatsApp from any of ISD codes, we strictly advise you to not pick the call and also block the number so that they cannot try calling you again. It is best to stay away from such scams by ensuring that whoever you interact with online is a trusted person.
