eSIM Cards does not offer a truly unlimited data eSIM for the Balkans. All plans that carry the word “Unlimited” in the name actually provide a fixed high‑amount data allowance, in this case 1,000GB per month, and after that limit the speed can be throttled. A more practical option for travelers is to pick one of eSIM Cards’ fixed data plans. For example, the UK Vodafone 500GB for 30 days plan gives 500GB of high‑speed data for a month and costs $30.04 USD, while the UK Vodafone 500GB Monthly Plan for 3 months offers 500GB per month for 90 days at $88.13 USD. Similarly, the UK Vodafone Unlimited Monthly Plans provide 1,000GB per month for 90, 180, or 365 days at $92.13, $180.26, or $352.51 USD respectively. These large‑allowance options tend to be more cost‑effective unless a traveler is an extremely heavy data user.
