Billion Connect does not provide a plan with unlimited data for Poland. Instead, the provider offers fixed data plans with explicit data caps: a 100GB plan valid for 30 days and a 50GB plan also valid for 30 days. These bundles include tethering, reduced speed at 128kbps, and use the 5G network in Poland. For travelers who need larger data allowances but do not require an unlimited supply, these fixed data plans can be a more economical choice unless they are very heavy data users.
