Ad Verification With Mobile Proxies
See campaigns exactly as real 4G/5G subscribers do. Route ad checks through genuine carrier IPs to confirm placements, catch fraud, and audit creatives across regions.

Why mobile proxies fit ad verification
Most ad fraud and misrendering happens on mobile, where carrier-level targeting decides which creative loads. Mobile proxies route your verification requests through real 4G/5G carrier IPs drawn from a pool of 2.5–3M daily active mobile addresses, so the ad server treats you as an ordinary subscriber. That clean reputation is the single biggest reason these IPs outperform other types for placement checks: networks rarely cloak or block them. You see the live creative, landing page, and redirect chain a real user would, not a sanitized version served to flagged traffic.
The verification workflow
Pick the country and carrier you want to audit, then request the publisher page or ad-tag endpoint through the proxy. Capture the served creative, click-through URL, and any redirect hops, then compare them against the campaign's expected placement and geo rules. Repeat across carriers and countries to map how a single line item renders for different audiences. Because each request can exit from a distinct mobile IP, you sample many impressions without one session contaminating the next, building an honest picture of delivery and surfacing cloaked or fraudulent ads.
Setup: targeting, sessions, protocols
Target by country plus carrier via ASN — the top-3 carrier ASNs are preset for Tier-1 and Tier-2 countries, and the ASN field accepts open input for anything else. There is no state or ZIP targeting on the mobile pool. Choose rotating sessions to sample many impressions fast, or sticky sessions lasting 1 minute to 2 hours when you need to follow a multi-step redirect or post-click flow. Connect over HTTP, HTTPS, or SOCKS5 with simple user:pass authentication; typical latency is around 387 ms and the pool supports up to 50,000 concurrent sessions.
Best practices
Match the carrier to the audience the campaign actually buys — verifying a carrier-specific deal through the wrong ASN proves nothing. Use sticky sessions when an ad's behavior depends on the full click-to-landing journey, and rotate when you only need a render snapshot. Spread checks across several carriers and countries rather than hammering one, so you catch geo-cloaking and regional creative swaps. Log the exit IP, ASN, and timestamp with every captured creative; that metadata is what turns a screenshot into defensible evidence when you escalate a fraud finding.
Common pitfalls
Do not expect state- or city-level granularity — mobile targeting stops at country and carrier, so plan audits around that scope. Reusing one sticky session for hundreds of impressions skews your sample and can trip frequency caps that hide the real creative. Treating SOCKS5 here as UDP-capable will fail: the mobile pool is TCP-based, with no UDP ASSOCIATE. Finally, remember verification is read-mostly traffic billed per gigabyte, so capturing full-resolution video creatives repeatedly burns bandwidth faster than text-based tag checks.
Pricing and scaling
Mobile bandwidth is pay-as-you-go per gigabyte, starting at $2.98/GB and scaling down to a $1.20/GB floor as volume grows. Ad verification is naturally bursty — heavy during a campaign launch, light afterward — so per-GB billing means you pay for the audits you actually run instead of a fixed seat. With up to 50,000 concurrent sessions, you can fan a single launch check across many carriers and countries in parallel, then throttle back to spot-checks. Scale spend by sampling smarter, not by paying for idle capacity.
