Yes, Roamify sells unlimited data eSIM plans that cover the Balkans, including Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, and Serbia. The plans are available in validity periods ranging from 1 day to 30 days, with prices from $4.47 USD for a 1‑day plan up to $49.97 USD for a 30‑day plan. All plans use 5G networks and allow tethering.
Because the plans are labeled as unlimited, the data allowance is not capped, but a Fair Usage Policy may apply. After heavy usage, speeds can be throttled, so travelers who need consistent high speed should contact Roamify to confirm the typical amount of data that remains at normal speed.
