JamboSim eSIM Data Plans for Poland

JamboSim does not provide a true unlimited data eSIM for Poland. All of its plans listed under the “Unlimited” name give a daily cap of 3GB; once the cap is reached, data speed is throttled to 1000kbps. If a user needs more data, the provider offers fixed‑data options instead.

For example, a 20GB plan is available for 30 days at $7.99 USD (5G), and a larger 50GB plan is offered for 30 days at $75.99 USD. These fixed‑data plans give a larger total data allowance and avoid the speed reduction that occurs after the daily limit in the “Unlimited” plans. Choosing a fixed‑data plan may be more cost‑effective for travelers who consume a lot of data.

JamboSim does not provide an eSIM for Poland that includes a phone number or SMS capability. Only data‑only plans are available. Travelers can still use popular VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging.

JamboSim offers 12 single‑country plans that cover Poland, and 47 multi‑country plans that include Poland as part of the coverage. The available plans span a price range from $1.99 up to $185.99 and data caps from 200 MB to 100 GB. For customers who want a set amount of data, the fixed‑data‑cap plans provide a specific data allotment, while the daily‑data‑cap plans adjust the data limit according to the number of days the plan remains active. Both single‑country and multi‑country options allow tethering, and reduced speed is applied when the data usage exceeds 1000 MB.
