Broj je u dobrom formatu, sms verifikacija je setovana jos 2014 i poruke su jedno vreme stizale. Ovaj problem je prisutan samo kod Gmail servisa, na drugim sajtovima radi ok. Posle poziva MTS call centru utvrdjeno je da 2 verifikacione poruka tog dana nisu stigle sa drugih sajtova (ovo je tacno, ponekad se desi, ali posle drugog pokusaja stignu), za Gmail nemaju evidenciju, iako sam pokusao bar desetak puta tog dana i xx prethodnih.
Jedno od objasnjenja sa Gmail support foruma-
"
If you were receiving codes before (and it had to work to even setup 2-step verification), the first thing to do is contact your provider and find out why the SMS 2-step codes are not being delivered since they were working fine previously (Note that Vodafone has been having problems for months that they can’t seem to fix and usually try to pass off on Google). Numbers recently ported to a new provider can cause problems, as can providers blocking texts from short-numbers (http://en.wikipedia.org/wiki/Short_code). These are not issues Google can fix."
Ovo nije izolovan slucaj, cesto se desava i u uredjenijim drzavama kod ozbiljnih provajdera...
