These are the two checks we do ourselves before a customer gets a line, and anyone can use them. No sign-up, nothing stored.
What IP am I on? One quick look shows your carrier, ASN, city, time-zone match and any WebRTC leak.
Free toolProxy checkerDrop in one proxy or a whole list (HTTP, HTTPS, SOCKS4, SOCKS5), see the exit IP, location, ISP and latency for each line, and export the ones that work.
Free downloadProxy Tester appDesktop app for Windows, macOS and Linux.
Which antidetect browser should I use with a day pass? Undetectable.io first: make one profile, set its time zone and language to the line's city, paste the HTTP or SOCKS5 details and run the check. GoLogin is our second choice. Both have free plans.
Starts free, runs on Windows and macOS, and keeps profiles locally or in the cloud. Give each profile its own USA 4G Proxies line.
Get Undetectable.io ↗Free for 3 profiles, on Windows, macOS and Linux, and there are phone apps too. Paste a USA 4G Proxies line as host:port:user:pass.
Get GoLogin ↗Partner links. If an antidetect browser takes an HTTP or SOCKS5 proxy, it'll work with our lines; here are the two we'd suggest.
Real carrier SIMs, unlimited rotation and eight live US metros to pick from. A day pass is $4; two hours are $2.
Want to test browser fingerprinting, bot detection, DNS and WebRTC leaks? We tell customers to try IPFighter's free suite, which goes nicely with a USA 4G Proxies line:
