371 is the country code for Latvia while 375 is the country code for Belarus. Two days ago, I missed calls twice from a number starting with +371 country code, both calls rang twice and disconnected abruptly before I could answer it. I got suspicious and decided to do a research into it. In the course of my research, I found out that most of such calls emanate from scam artists. So, if an unsuspecting recipient of such calls decides to call the number back, he’ll be charged an exorbitant international call fee, a portion of which may be paid to the scammers who orchestrated the missed calls.

In conclusion, while some of these calls may be coming from genuine callers from Belarus and Latvia, majority of them are suspect and should be treated with caution. In fact, it is safer to not return missed calls from phone numbers with those country codes unless you know the numbers or are expecting calls from those regions.
