Strange calls from different counties?

I’ve gotten a few from Russia. A couple from Mexico. My mom just got one from Jamaica. They don’t say anything when you answer. What is up with these Has anyone gotten one? I’ve also gotten calls and the call will just be a long bunch of numbers. Again no one will answer. Or someone will call the landline and the phone will only ring once or twice. Or they will hang up as soon as you answer Kinda spooky. Has anyone been getting strange phone calls?

You shouldn’t answer any suspicious calls, certainly not from other countries. That’s what hackers and scammers do. Some kind of tricks they play. I never answer and I block suspicious callers

Yes! Plenty of time.

There was the one ring scam. I do not know if it is still going around but it would be foreign countries calling to see if you answered and if you did somehow or another they would hijack your international call privledges and run up your bill.
