All calls made to the numbers of mobile and landline operators that provide their services in the Western Balkans region (more precisely: all calls made to the area codes +381, +382, +383, +387, +389 and +355) are regulated calls and are charged in the same way as in domestic traffic, except for packages with a different unit price for calls to the Yettel network and to other networks in domestic traffic, for which regulated calls are subject to the price that applies to calls to other networks in domestic traffic.
Odlazni pozivi upućeni ka bilo kojoj trećoj destinaciji van teritorije Zapadnog Balkana (odnosno ka bilo kom pozivnom broju osim gorenavedenih) ne spadaju u regulisane pozive i tarifiraju se po cenama saobraćaja koje važe za Zonu 1 one roming tarife koja je aktivna na pretplatničkom broju (kod roming tarife 10/50 MB do kraja dana ta cena iznosi 54,9 din/min uz naknadu za uspostavu veze od 89,9 dinara, a kod roming tarife Standard cena je 119,9 din/min uz naknadu za uspostavu veze od 7,9 dinara). Roming dodaci Evropa 25 minuta 7 dana i Evropa 50 minuta 15 dana se primenjuju za ove pozive upućene ka trećim destinacijama van regiona Zapadnog Balkana.
For tariff packages that have additional traffic in the Yettel network (5,000 minutes after minutes to all networks are used up), that traffic will not be able to be used in the Western Balkans region, but will be treated as calls made to numbers outside the Yettel network.
Free calls or calls at a preferential price that business users have within a closed user group (Closed User Group - CUG or Virtual Private Network - VPN) will not be valid in the Western Balkans region, but such calls will be treated as calls made to numbers outside the Yettel network..
Users who, within the tariff package (Premium, Premium Total, Total Data+, Yettel Mobile L) have/use minutes for international traffic (25 countries) from Serbia, these calls are not applicable when the user is roaming, i.e. in the countries of the Western Balkans.
