JamboSim’s plans that carry the “Unlimited” label are not truly unlimited. Each of those plans provides 3 GB of high‑speed data per day (validity ranging from 3 to 30 days); once the daily quota is reached the speed drops to 1000 kbps.
Instead, the provider sells fixed‑data bundles that may be more cost‑effective for heavy users. For example, a 100 GB plan with a validity of 180 days or a 50 GB plan valid for 30 days are available for travelers in the Balkans. These fixed‑data options offer a large amount of high‑speed data without the daily cap present in the “Unlimited” plans.
JamboSim does not provide a Balkans eSIM that includes a phone number or SMS capability; all its Balkans plans are data‑only. Travelers who need voice or text can rely on popular VoIP applications such as WhatsApp, Telegram and iMessage, which work over the data connection.
JamboSim’s eSIM plans (currently listed without specific names) provide coverage across the entire Balkans region, including Albania, Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia, Serbia, Kosovo, and Bulgaria.
