Best mobile proxies for antidetect browsers, compared

The short answer

An antidetect browser isolates the fingerprint; the proxy supplies the network half of the identity, and it is the half the browser cannot fake. For the profiles you cannot afford to lose, QuanticData mobile is the proxy we would put in the field: one sticky carrier IP per profile with a session lifetime up to 24 hours, the country and, where the catalog lists it, the carrier chosen in the username, HTTP or SOCKS5 on the same credentials, and $5 for 1 GB with no port rental, which is what a profile that moves megabytes a day actually costs to run. For dozens of low-stakes profiles, our residential network does the same per profile from $1.00/GB.

The rules that matter more than the vendor: never share a session between two profiles, set the TTL to the time the profile stays open, keep the profile's time zone and language consistent with the exit, and remember that no proxy changes a platform's rules on multiple accounts.

What an antidetect profile needs from a proxy: seven criteria

Mobile, residential or ISP for a profile?

A working split for a team: mobile for the top tier of profiles, Residential Premium for profiles that stay open all day, Residential Basic for short sessions and testing. The browser does not care which; the username does the routing.

The five browsers: where the proxy goes

All five take the same four values, host, port, username, password, per profile, and all five have a check button. The names of the tabs differ and move between releases; the values never do. One page per browser, with the steps and the fixes:

Sticky session rules for profiles

The whole configuration travels in the username, so the profile's proxy settings never change once written. USER and PASS stand for the credentials in the dashboard; the host and port are the ones shown there.

# one profile, one session, alive for 12 hours, US exit on T-Mobile
      USER-country-us-isp-t_mobile_usa-sid-profile01-ttl-720m
      
      # a second profile: a different session ID, never the first one
      USER-country-us-isp-t_mobile_usa-sid-profile02-ttl-720m
      
      # a UK profile without carrier pinning, 24-hour lifetime
      USER-country-gb-sid-ukshop-ttl-1440m

• One ID per profile, never reused. Two profiles sharing a session ID share an exit, which is the one thing an antidetect setup exists to avoid.
• TTL equal to the time the profile stays open. When the TTL expires the next request gets a new exit; if the profile is still logged in, that is the address change you did not want. Use 1,440 minutes for profiles that stay open all day.
• Country from the account, not from convenience. Match the profile's time zone, language and keyboard to the exit's country; the browser's check button shows the country and time zone it will see.
• Carrier only where it helps. Pin an operator when a phone-like profile should look local; leave it out to rotate across all operators of the country when it should not matter.

Published prices, and what a profile costs to run

Entry prices of mobile proxy providers as published on their own pages on 13 September 2026, from the mobile comparison, where the full table of 15 sits. Per-port and per-device models are the ones to translate before comparing: a profile that moves 100 MB a day costs about $0.23 a day at $2.30/GB, against $8.49 a day for a rented port.

Proxy check failed, connection failed: the usual causes

Across the five browsers the searches for "proxy check failed", "proxy not working" and "connection test failed" outnumber the searches for the product. The causes are almost always one of these, in this order.

What this page does not promise

A proxy supplies the network half of a profile's identity. It does not make an account "undetectable", it does not change a platform's rules on multiple accounts, and an antidetect setup used to break those rules is still against them. QuanticData proxies are for keeping legitimately separate accounts separate and consistent: agency clients, regional QA, multi-store operations where the marketplace allows them. We measured latency, country match and session stickiness on our network; we did not measure, and do not claim, any success rate on any platform.
