I recently started receiving verification codes for services I am not using (Klarna, TEMU, etc). It seems someone is using my number to set things up. I am curious (1) if they are trying to receive verification codes, are they able somehow to see them come thru (hacking, spy ware, etc); (2) Do I need to worry about these incoming messages or just ignore them? What can Verizon do / I do to verify that I am not hacked?
