Since I have a kind of paranoia, even I stay for 2 days in a country, I tries to buy a local SIM card, fortunately, it is cheap recently, easy and quick connected to the network, also in Balkan countries.

In Slovenia, I bought the prepaid SIM Card by SI Mobile.

The shop was conveniently located in the corner of the main square of Ljubljana Old Town.
Bought the data package only, if I remember correctly, 5 GB for EUR 10.
Passport required.
There were no mobile phone shops in the airport, only vending machine.
In Montenegro, I bought the SIM Card in a kiosk in the shopping center Kamelija just outside the Old Town wall of Kotor. The guy in the kiosk failed to activate, so he went to the official shop of the mobile phone company in the same mall.
I forgot the price, but I think it was about EUR 5.
No passport required.
In Bosnia, with the help of the hotel guy, I bought the SIM Card from a kiosk on the main pedestrian street in the Turkish part of the old town in Sarajevo. The kiosk staff explained to the hotel guy how to activate the card, but the guy failed, so I went back to the kiosk and the kiosk girl helped me to activate the card.
The card was from Go! Free.

In Bulgaria, I bought the prepaid SIM Card by VivaCom.

I went to Mall of Sofia. There were 3 mobile phone company shops, including the biggest Telenor, but when I asked, only VivaCom had the prepaid SIM Card.
I bought a package of 1 GB data and 100 minutes local call for BGN 10 (EUR 5).
If I remember it correctly, the data only package was 5 GB for the same price.
The shops in Mall of Sofia opened till 9pm, but the shops in the main pedestrian street closed earlier at 6pm.
Required passport.
