eSIM Roamless pour Poland en 2026

Plus is the only network Roamless names for Poland, so the radio choice is settled before you pick a plan; its catalogue has a large range, making data sizing the real decision rather than network selection. Roamless lists 5G as the fastest technology here, though that is a ceiling, not a promise for every handset or location. It has not published where traffic breaks out, so the resulting delay and IP location are unknown. Top-up is stated as available, allowing an exhausted plan to be extended rather than rebought.
