TELECOMS IN BULGARIA.

Below are the 3 biggest mobile phone networks in Bulgaria, all of these work in conjunction with any U.K. European or Global Network and will bill you via your own network provider under the International Roaming System.

When Visiting Bulgaria and switch your phone on for the first initial time in the country, it will take about 30 seconds longer as your mobile will search the area for the most strongest signal, this should then display the name of the network on your phone and signal strength. You need to check beforehand the network charges when making a call from Bulgaria.
