Serbia requires providers to block unlicensed foreign gambling sites by IP address, the numeric address of a server. An address block can also catch an unrelated site sharing that address. Linkspect checks Serbian home and mobile connections in testing mode, but can currently identify an IP block only on mts lines.
Source for the blocking rule: National Assembly, 2024 gambling-law amendment, article 64, checked 14 November 2026. Shared-address effects are our technical inference; product coverage is described below.

The page is opened through home and mobile connections of mts and Yettel / SBB and mobile connections of A1 Srbija, the way their customers would open it, and the answer comes provider by provider.
Who orders gambling blocks in Serbia?
Article 122(5) of the Gambling Law provides for an inspector to prohibit a foreign operator from offering online gambling without Serbian approval. The decision goes to the competent authority for IP blocking through communications operators. The Gambling Administration says the amendments apply from 6 January 2025.

The rule targets server addresses. A domain name alone therefore does not tell you whether your site could be affected: shared hosting and content delivery networks, which serve many sites from shared infrastructure, can put unrelated sites on the same address. This is a consequence of address-level blocking, not a claim that we measured mistaken blocks in Serbia.

Why can an IP block look like an outage?
An IP block gives the visitor no warning page: the connection to the blocked address simply fails. We found no government warning page in the Serbian sources checked on 14 November 2026. The law does not specify a warning destination or exactly how each provider must make the connection fail, and we have not tested blocked sites. This does not prove that no provider ever shows a page.
Sources checked: National Assembly, gambling-law amendment · Gambling Administration, questions and answers; 14 November 2026. Connection failure describes address blocking, not a measured result on every Serbian network.
If a visitor reports a failure, save their provider, home or mobile connection, the time and the exact browser error. Keep the server address your site used then, too. A later successful connection cannot explain the earlier failure by itself, and a site with several addresses may still open through another one.
Can an optional security service show a warning?
Provider security services are separate from gambling orders. mts offers Siguran Net for mobile connections and Siguran kućni Net for home connections, activated by the subscriber. Their privacy notice covers visited domains and IP addresses, with retention up to six months from creation. A line using one of these services should not be treated as having no logging.

Yettel's optional Safe Net uses domain filtering on its mobile service and describes warning pages for standard web ports. Its terms exclude Wi-Fi, cable and ADSL access. Ask which service is enabled when investigating a complaint; a provider's name alone does not establish which filters are active on the visitor's line.

Which Serbian providers should your comparison include?
RATEL's Q2 2026 figures describe subscriptions, not people. For the two providers in our main home comparison, the shares below are of the whole fixed-broadband market; RATEL does not label this table residential-only.
| Home comparison provider | Share of fixed-broadband subscriptions |
|---|---|
| mts / Telekom Srbija | 59.0% |
| Yettel, including SBB | 32.2% |

SBB legally merged into Yettel on 1 April 2026, while its brand continued. It is included in Yettel's figure, not a separate market share. That corporate change alone does not establish identical filtering across their access networks.

The mobile table uses active mobile subscriptions, not just mobile-broadband subscriptions. These are the three providers in our main mobile comparison.
| Mobile provider | Share of active mobile subscriptions |
|---|---|
| mts / Telekom Srbija | 41.48% |
| Yettel | 32.16% |
| A1 Srbija | 26.36% |

What does linkspect measure in Serbia?
Serbia is open in testing mode on mts and Yettel/SBB home connections and mts, Yettel and A1 mobile connections; results may be incomplete. Today an IP block can be named only on mts, and only when the check proves the site's address through the provider's DNS, the lookup that turns a domain into an address; on Yettel and A1 a connection failure returns "no result", never an IP-block verdict. On Yettel and A1, a page that loads has its address checked using public DNS when that step can run; otherwise it stays "not verified", while mts lines sharing one public address among customers can also prevent us from proving an IP block. In our deployment check on 14 November 2026, example.com opened on all five groups with "likely" confidence and the IP check completed on each, but no blocked site was tested.
