My wife and I were doing a tour of the Balkans and wanted an eSIM which covered North Macedonia, Kosovo, Albania, Montenegro and Serbia. The info on Kosovo said in one place that it was covered and in another that it wasn't - in the event it wasn't, and neither was Serbia. When it worked it was fine. My wife chose a different eSIM which worked in all five countries.

For few days in Greece I had Edge instead of 4G/5G, it was so bad that I couldn't order taxi. Then it switched to 5G.

Everything worked fine, however, even though Kosovo was on the list of the countires that the plan that I selected, Ovosim did not work in Kosovo. I was dependent on my normal cellphone plan for roaming.

Issues with Sim when transferring from Georgia to Armenia. Needed WiFi to resolve - ended up buying another sim, so couldn’t then get another from ovo

No warning 10 gigs went so quick
Response from OvosimSep 9, 2026
Hi Stevo, thanks for the feedback and sorry the 10GB ran out sooner than expected. We looked into your usage on this eSIM and saw some heavy days, over 1.5GB used in single sessions a couple of times, which is more typical of video streaming or large downloads than general browsing. At that rate, 10GB gets used up faster than most travelers expect. We know it's frustrating when it happens without warning, that's something we're looking at improving (a usage alert before you hit your limit). In the meantime, happy to point you toward one of our larger data plans for future trips if that'd help avoid this next time.
