Mobile Proxies for AutoTrader

QuanticData mobile proxies work with the AutoTrader app on Android and iPhone: the phone's traffic leaves through the proxy and AutoTrader sees the carrier IP, with country and session set in the username exactly as on a desktop. On iPhone the proxy is set per Wi-Fi network (HTTP with username and password) or in a client such as Shadowrocket for SOCKS5; on Android the Wi-Fi proxy setting has no password field, so use IP whitelist authentication or a proxy client app. Some apps ignore the system proxy and only work through a client app that tunnels the whole device.

QuanticData recommends rotating IPs for AutoTrader. Rotate per search or listing page; use a sticky session with city targeting when a run must keep one search location constant. Sessions are set in the username (a session ID and a lifetime, up to 1,440 minutes (24 hours)), so no proxy list is needed.

QuanticData customers confirm that both the country site and the search location shape what AutoTrader returns: distance sorting, local dealers and regional pricing. A residential exit in the buyer's city, paired with the matching postcode or ZIP in the query, is what makes collected prices comparable to what a local buyer sees.

QuanticData gives you host, port, username and password the moment a plan is active: create a free account, open Plans → Mobile, pick a bundle ($5 for 1 GB to start) and copy the credentials from the dashboard. Set the proxy per request with city targeting matching the postcode or ZIP in the search; render with a headless browser where the listing grid loads dynamically. For AutoTrader, the countries asked for most are the United States, the United Kingdom and Canada, with carriers such as T-Mobile and AT&T Wireless selectable in the username for the United States.

QuanticData mobile proxies are standard HTTP and SOCKS5 endpoints with a host, a port, a username and a password, so any client that accepts a proxy node works, Proxifier included: enter those four values as a proxy server of type HTTPS or SOCKS5 in Proxifier on the desktop, with a rule for the application, and AutoTrader traffic from the applications matched by the rule leaves through the exit set in the username. For AutoTrader leave the session out of the username so every new connection rotates to a fresh IP, or add a session ID when a flow must keep one. Host and port are in your dashboard; the HTTP and the SOCKS5 port are different, so pick the one that matches the node type.

QuanticData does not give away mobile proxies for AutoTrader: the smallest mobile bundle is $5 for 1 GB, and the free option is the residential trial — 100 MB on Residential Basic for 5 days, no card — enough to test your setup against AutoTrader from a home IP before paying for carrier IPs. Public "free proxy" lists are shared addresses the storefronts already know, which is why they answer with captchas or empty pages; they also change daily, so nothing built on them keeps working for long.

QuanticData's answer for AutoTrader is mobile, the network this page is about: AutoTrader is used mostly from phones, and a carrier IP shared with real handsets behind CGNAT, held on a sticky session for up to 24 hours, is what its accounts expect. Residential is the cheaper choice for reading public AutoTrader data at volume, from $1.00/GB; the residential page for AutoTrader covers that side.
