Mobile proxy fraud score, tested on 55 carrier exits in 11 countries

Mobile proxy fraud score, measured on 15 October 2026: we opened 55 QuanticData mobile exits in 11 countries with the carrier pinned and looked each address up off the proxy. On proxycheck.io 50 of 55 scored 0 out of 100 and the median was 0 in every country. IP2Location.io flagged none of the 55 as a proxy.

"0 fraud score" is the phrase buyers search for and sellers print in their titles, usually without saying which service gave the zero, on which address, or when. This page is the opposite: one evening, two public services, the settings and the time of every lookup, and the per-country summary in results-2026-10-15.csv.

What we checked, and how

A fraud score belongs to one IP address at one moment, on one service. So the test reads the address each exit actually used, then asks the services about that address straight away, from outside the proxy.

Item	Setting
Date and time	15 October 2026, 20:13 to 20:16 UTC
Network	QuanticData mobile (4G/5G), rotating, one request per exit
Countries	United States, United Kingdom, Germany, Brazil, India, Italy, South Korea, Greece, Indonesia, Russia, Philippines
Exits	5 distinct addresses per country, 55 in total, the carrier pinned in the username and taken in turn from the carriers listed on each country page
Exit address	read through the proxy from ipinfo.io/json, the same command as the example on our country pages
Reputation, service 1	proxycheck.io API v3, default settings, no API key: risk score from 0 to 100 plus proxy, VPN, Tor, hosting and compromised detections
Reputation, service 2	IP2Location.io API, no API key: proxy flag and country
Not published	the IP addresses themselves

Both services were queried within seconds of the exit being read, one lookup at a time and well inside their free daily limits. We picked them because their terms allow automated lookups by a business; we did not scrape score pages whose terms forbid it.

Results at a glance

Measure	Result
Exits checked	55 in 11 countries
Exits in the requested country (ipinfo.io, proxycheck.io and IP2Location.io agree)	55 of 55
Risk score 0 on proxycheck.io	50 of 55
Median risk score on proxycheck.io	0 in each of the 11 countries
Flagged as VPN, Tor, hosting or compromised on proxycheck.io	0 of 55
Flagged as a proxy on IP2Location.io	0 of 55

On proxycheck.io a risk score starts from a baseline set by what the address is used for (hosting, VPN, scraper, Tor, proxy) and rises with recent attacks seen from it. A score of 0 therefore says that, at the moment of the lookup, the address was not in any of those groups and had no attack history, which is what a carrier address shared by ordinary phones should look like.

Country by country

Country	Carriers pinned	Exits	Median risk score
United States	AT&T Wireless, T-Mobile, Verizon Wireless, C Spire	5	0
United Kingdom	BT, O2, Three	5	0
Germany	Deutsche Telekom, Vodafone, O2	5	0
Brazil	Vivo, Claro, TIM Brasil	5	0
India	Jio, Airtel, Vodafone Idea, BSNL	5	0
Italy	TIM, Vodafone Italia, WindTre, Fastweb	5	0
South Korea	KT, LG Uplus, SK Telecom	5	0
Greece	Nova Greece, Vodafone Greece	5	0
Indonesia	Telkomsel, Indosat, XL Axiata, Smartfren, Orion Cyber Internet	5	0
Russia	MTS, Megafon, Beeline, Tele2 Russia, T-Mob	5	0
Philippines	Smart Communications, Globe Telecom, Globe Business Gfiber Broadband Plan, Dito Telecommunity	5	0
All 11	40 carriers	55	0

Each of these 11 country pages now carries its own line from this run: the carriers we pinned, the date and the result. Eight of them also show the network (ASN) each carrier's exits came out on, measured the same day, so you can compare a carrier, its ASN and its reputation in one place.

Why carrier exits score low

A mobile operator puts thousands of subscribers behind each public address with carrier-grade NAT. Fraud and proxy databases know this: an address that serves a whole neighbourhood of phones cannot be blocked without blocking real customers, and most of the traffic behind it is ordinary app and browser use. That is the structural reason QuanticData mobile proxies sit at the bottom of the scale, and why datacenter ranges, which a hosting flag catches at once, sit at the top.

It is also why the result depends on the service you ask. Each checker has its own data and its own model: one weighs recent attacks, another the share of suspicious traffic it has seen from the whole carrier, another lists of known proxy endpoints. The same address can read 0 on one and higher on another, and any score can move over days. Treat a number as a snapshot of one address on one service, and write down which one.

How to check the exit you were given

Check the address your session actually uses, not the gateway hostname, and check it on the service your target cares about. With a sticky session the address holds for the session lifetime, so one lookup covers the whole job.

# 1. read the exit address through the proxy
curl -x "http://USER-country-de-isp-deutsche_telekom_ag-sid-check01-ttl-30m:PASS@$PROXY_HOST" https://ipinfo.io/json

# 2. look that address up off the proxy (replace EXIT_IP)
curl "https://proxycheck.io/v3/EXIT_IP"

Note the service, the settings you used and the time, as we did above. If an address does not suit you, start a new session id and you get a new exit from the same carrier and country. To time and compare exits across countries without writing code, the proxy tester builds the same commands in curl, Python and Node.

Job	What to check	Why
Account work on a social or marketplace app	The sticky exit, once per session, on the checker you rely on	The address holds for the session lifetime
Ad and content checks by market	Country and carrier of the exit, then the score	The view depends on the carrier and the country
A fixed address with a known score for weeks	A static ISP address instead of a rotating mobile one	Mobile addresses rotate by design

If you need one address that keeps a low score for weeks, a rotating mobile pool is the wrong tool: see low fraud score ISP proxies: a private static address kept for a renewable 30-day term.

Limits of this test

• One evening, five exits per country: enough to see a pattern by country, not to promise a rate for every address.
• Two services. Other checkers use other data, and their numbers for the same address can differ.
• A score describes one address at one moment; mobile addresses rotate and scores change over time.
• We looked up reputation only. How a platform treats an account depends on much more than the address; for what two big platforms return through these exits, see the Instagram and TikTok test of 4 October 2026, and for speed, sessions and geo match, our 98-request test of the mobile network.

The setting to buy and what it costs

For the workflows above: the mobile network, the country and, if you want it, the carrier in the username, rotating or sticky, HTTP or SOCKS5. Pinning a carrier is -isp- plus the code shown on each country page; leaving it out rotates across every carrier of the country.
