How do I check if my offer is blocked by Vivo, Claro, Jio, MTS, or Turkcell?
Published 2026-05-27 · 7 min read
TL;DR
Run one per-carrier check against the offer URL from real residential and mobile networks on each operator's ASN: Vivo (AS26599 / AS27699), Claro (AS28573), Jio (AS55836), MTS (AS8359), Turkcell (AS16135). The pattern across all 5 tells you the cause: all 5 fail with the same Cloudflare challenge → WAF rule; failures cluster in one country → regulator order; single carrier fails → operator-level filter. Status + DNS + final URL + screenshot per carrier.
Why these five carriers
Vivo (Brazil) — largest BR mobile operator; first to enforce Anatel orders.
Claro (Brazil) — wide BR coverage; aggressive WAF defaults; covers América Móvil group ASNs.
Jio (India) — largest IN mobile by subscribers; own-initiative content filter even without DoT order.
MTS (Russia) — largest RU mobile; first to enforce Roskomnadzor blocks; close to government enforcement.
Turkcell (Turkey) — largest TR mobile; carries BTK block orders quickly; mobile-first market.
How to run the check (step by step)
- 1
Build the 5-carrier ASN list. Vivo (AS26599 / AS27699 mobile), Claro (AS28573), Jio (AS55836), MTS (AS8359), Turkcell (AS16135). Add fixed-line variants if relevant (Vivo AS26599, MTS AS43933).
- 2
Run one check per carrier from real consumer networks inside each country. Datacenter IPs and commercial VPN exits bypass the exact filters the carriers apply.
- 3
Capture HTTP status, DNS result, final URL, and a screenshot per carrier. The screenshot is the proof; the status code is the signal.
- 4
Compare patterns across all 5 carriers. All 5 fail with the same Cloudflare challenge → WAF. Failures cluster by country → regulator order. Single carrier fails → operator-level filter on that ASN.
- 5
Cross-check against a datacenter probe. If a cloud ping returns
200and consumer ASNs return errors, the server is fine — the path is filtered. - 6
Alert per carrier independently. Averaging hides single-carrier blocks. A pause-on-failure alert per ASN lets you cut spend within minutes.
5-carrier reference table
| Carrier | Country | ASN (mobile) | Regulator | Typical block |
|---|---|---|---|---|
| Vivo | Brazil | AS27699 | Anatel | 451 / DNS error / block page |
| Claro | Brazil | AS28573 | Anatel | 451 / block page |
| Jio | India | AS55836 | DoT (Sec 69A) | 403 / jionet block page |
| MTS | Russia | AS8359 | Roskomnadzor | DNS error / connection reset / RKN block page |
| Turkcell | Turkey | AS16135 | BTK | DNS poisoning / BTK redirect page |
Multi-carrier patterns and what they mean
| Pattern | Likely cause | Action |
|---|---|---|
| All 5 carriers see same CF challenge | Cloudflare bot / WAF rule against residential | Loosen CF Bot Fight / firewall rules. |
| All 5 carriers see DNS failure | Origin DNS issue or registrar/NS issue | Check DNS provider, then origin server. |
| Failures cluster in BR only (Vivo + Claro) | Anatel order | Switch BR traffic to mirror; pause BR sources. |
| Failures cluster in IN only (Jio) | DoT order or Jio operator filter | Verify Airtel / Vi too; pause IN sources hitting Jio. |
| MTS fails alone | Roskomnadzor list or MTS-specific filter | Mirror; check Beeline + Rostelecom to confirm. |
| Turkcell fails alone with DNS poisoning | BTK order | Mirror; verify Turk Telekom + Vodafone TR. |

FAQ
How do I check if my offer is blocked by Vivo, Claro, Jio, MTS, or Turkcell?
Run a single per-carrier check against your offer URL from real residential and mobile networks on each operator's ASN: Vivo (AS26599 / AS27699 mobile), Claro (AS28573), Jio (AS55836), MTS (AS8359), and Turkcell (AS16135). Look at status code, DNS result, final URL, and screenshot per carrier. If three or more fail simultaneously across countries it's most often a Cloudflare or WAF rule. If failures cluster by country it's a regulator order. If only one carrier fails it's that operator's own filter.
Why these five carriers specifically?
Vivo, Claro, Jio, MTS, and Turkcell are the dominant mobile operators in five of the most-restricted markets for paid traffic and iGaming: Brazil, India, Russia, and Turkey. Combined they handle the majority of consumer mobile traffic in those countries and they enforce regulator orders (Anatel, DoT, Roskomnadzor, BTK) faster than fixed-line carriers. If your offer is blocked anywhere, it usually shows up on one of these five first.
Can I use a VPN to check instead?
No. Commercial VPN exit IPs are almost always on datacenter or hosting ASNs that bypass the exact filters the carriers apply to residential and mobile users. A clean check on a VPN tells you nothing about what a Jio mobile user or a Turkcell subscriber actually sees. Use real residential / mobile ASNs inside each country instead.
What does it mean if all five carriers fail at the same time?
Simultaneous failure across carriers in different countries usually means a global cause — most often a Cloudflare WAF rule treating residential and mobile IP ranges as bot traffic, an origin going down, or a DNS issue. Open the screenshots: if all five show the same Cloudflare challenge page, it's a WAF problem. If they show different country-specific block pages, four separate regulator orders happened to coincide — rare but possible.
How often should I run a multi-carrier check?
For active paid traffic campaigns, every 30 minutes is the minimum useful frequency. Regulator orders propagate to mobile carriers in 1–4 hours; Cloudflare rule changes propagate in minutes. A 30-minute check window catches the block before more than a few hours of spend hit a blocked URL. For mission-critical mirror domains, 5–10 minutes.
Do these carriers block differently on mobile vs fixed?
Yes — and this is the most common diagnostic blind spot. Vivo Mobile (AS27699) often filters differently from Vivo Fixed (AS26599); Airtel Mobile (AS9498) differs from Airtel Broadband (AS24560); MTS Mobile (AS8359) differs from MTS Fixed (AS43933). For Jio, almost all consumer traffic is mobile so a single ASN check is enough. For Turkcell, mobile (AS16135) is the dominant path.
