If you’re planning a trip to Montenegro, one of the first questions you’ll probably ask is whether you should buy a local SIM card after arrival or install an eSIM before you travel.
Both options provide mobile internet, but they offer very different travel experiences. A local SIM card usually requires visiting a mobile operator after landing, while an eSIM can be purchased online and installed before you even leave home.
Quick answer: for most tourists visiting Montenegro, an eSIM is the more convenient option because it can be installed before departure, works immediately after arrival and allows you to keep your regular SIM card active.
