JamboSim eSIM Data Plans for Poland

JamboSim does not provide a true unlimited data eSIM for Poland. Every plan listed for Poland has a hard cap of 3GB per day, after which the connection is throttled to about 1 Mbps. If a traveler prefers a larger static data allocation, options such as the eSIM Poland Unlimited / 30 days plan for 3GB/day or the eSIM JamboSim Europe 50GB / 90 days plan, which offers 50GB for 90 days, are available. These fixed data plans can offer better value if a user does not need truly unlimited usage.

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 and 52 multi‑country plans that include Poland, a total of 64 options. Prices range from $1.99 to $195.99 and data caps span 200 MB to 100 GB. Customers can choose between daily data‑cap plans, which reset each day, and fixed data‑cap plans that provide a set amount of data for the entire validity period.
