JamboSim eSIM Data Plans for Poland

JamboSim does not provide a truly unlimited high‑speed eSIM for Poland. The plans that carry the name “Unlimited” actually allow only 3GB of high‑speed data per day and reduce speed to 1000 kbps once that daily limit is reached. For travelers who need more data without hitting a daily cap, JamboSim offers fixed‑data options. A popular choice is the eSIM Poland 20GB / 30 days plan, which delivers 20GB of high‑speed data over a month for $6.99, and higher‑capacity plans such as the eSIM JamboSim Europe 100GB / 180 days plan for $195.99. These fixed‑data plans can be more cost‑effective for heavy data users than the daily‑limited “Unlimited” options.

JamboSim provides a range of eSIM plans that include a phone number and the ability to send text messages for travelers in Poland. The plans start at $11.99 USD for 1GB of data that is valid for 7 days and go up to $105.99 USD for 20GB of data that is valid for 365 days. Each plan uses a phone number with the dialing code +1 – a United States number – and allows you to make outbound calls and send outbound text messages, but it does not support inbound calls or inbound text messages. If you need specific functionality, it is a good idea to confirm details directly with JamboSim.

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.
