eSIM Roamless pour Czech Republic en 2026

O2 is the only network Roamless names for Czech Republic, so the radio choice is settled before selecting a plan: the meaningful differences are allowance and validity, not signal. Roamless lists service up to 5G, a stated ceiling rather than a promise for every handset. Its catalogue covers a large range, making data sizing the main decision and risking more data than a fortnight needs. Traffic breakout is not stated, so local latency and apparent IP location are unknown. Tethering is supported, which decides whether a laptop can get online.
