JamboSim eSIM Data Plans for Poland

JamboSim does not sell a plan that provides truly unlimited high‑speed data in Poland. All plans that carry the word “Unlimited” give 3GB of high‑speed data per day; after that limit is reached the connection is throttled to 1000kbps. For travelers who need a larger, uninterrupted data allowance, JamboSim offers fixed‑data options, such as a 100GB plan valid for 180 days or a 50GB plan valid for 30 days, which give a higher total data volume before any speed reduction.

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 publishes 12 single‑country data plans that cover Poland and 96 multi‑country plans that also include Poland in their coverage. The plans range in price from $0.99 to $195.99, and the data allocations span from 200 MB to 100 GB. The single‑country offerings are primarily fixed‑data plans, giving a set amount of data for a specified validity period, while the multi‑country set contains both fixed plans and daily‑cap options, letting customers choose between a fixed amount of data for the entire validity or a daily data cap that limits how much can be used each day.
