PSB Proxy is a proxy service run by UK-registered PSB HOSTING LTD, offering a pool of 90M+ IPs across 195 countries.
The lineup includes residential, 4G/5G mobile and datacenter proxies billed per GB, plus static DC and ISP addresses from $1 per IP per month. It supports HTTP(S) and SOCKS5, per-request or timed rotation, sticky sessions up to 1,000 minutes, city/ZIP/ASN targeting and a Public API.
Purchased traffic never expires, and unused balance can be refunded. Media buyers will appreciate the mobile IPs and compatibility with Dolphin Anty, AdsPower and Octo Browser. The lowest rates apply only to 10,000 GB packages, so grab the $5 test credit from support before buying.
