Portproof sells proxy traffic by the GB. One balance works on two shared pools: mobile 4G/5G (carrier modems in the US, UK, France, Netherlands, Poland and Georgia (country)) and residential (countries shown live on the Portproof locations page). You choose pool, country, rotation and sticky session in the proxy username, so one credential covers every setup, over HTTP or SOCKS5.
The price per GB falls as the order grows, from EUR 1.99 to EUR 0.89, and purchased GB never expire. Start with a 1 GB trial for EUR 1.49, once per customer. Unused whole GB are refundable within 14 days. Payment is by cryptocurrency.
