Please tell me, does A1 have roaming in Bosnia and Montenegro?
For an additional fee
In the region Z.Balkans, entry is free. Calls and internet are at basic home rates. You can purchase roaming packages, but also some part of the home package can be used while roaming - see the conditions of specific packages.
The number at the end is the amount of GB of traffic. 1 GB for 3 days, 2 for 7, and so on.
Is it on a postpaid SIM card? I have prepaid and there is no such option.
@Toma: This is a prepaid SIM card, but it is registered under documents (I don't know if it matters or not).
@Alexey: I understand, it probably plays. Thank you.
@Toma: If the trip is for a long time, google their operators, I saw ads in Sarajevo with offers for tourist SIM cards, I can't remember the prices unfortunately, but it might be more profitable. Or check AirAlo, if your phone supports eSIM.
