It is important to note that the 2023 Benchmark scoring campaign was assessed according to ETSI 103 559 Annex A scoring methodology.
In assessing the overall performance and the overall score of each mobile network, 5 main categories of services have been evaluated:
The above-mentioned categorisation is applied in parallel with the area categorisation. Based on ETSI 103 559 Annex A, three main areas are distinguished, which are then further divided up into categories.
Having applied this methodology, Telekom Srbija achieved 90.32 (out of 100) scoring points, followed by A1 Srbija with 90.12 (out of 100) scoring points and Yettel with 88.17 (out of 100) scoring points. The final results for Telekom Srbija and A1 are really close and these operators can be treated as equal in terms of quality of service.
This year, benchmark results showed an improvement of the quality of services in mobile networks, compared to 2022.
The Mobile Network Benchmarking results achieved in each category of services and on every measurement aggregation, as well as the overall scores achieved, are presented in Figure 1 below. Values for aggregations on the right are weighted values, as used for the calculation of the final score.

Scores for data tests including data transfer (DL/UL), web browsing, YouTube and messaging are presented on Figure 3 below.

Results for the 5 main categories of services for all three operators are shown in Figure 4. Values for respective services show the percentage of the maximum score achieved, to assess the gap in quality.
Fig.4. Results by 4 main categories of services for all three operators
All three mobile operators achieved good KPI levels in most of the aggregations for voice services. On Railways, the quality of voice service is poorer for all. These results require improvement.
Telekom Srbija scored best in most of data services (Messaging, Browsing, You Tube). In Data transfer performance, A1 Srbija reached the best result, due to higher throughputs for small file transfer. Both operators scored between 55% and 60% of the maximum points in this test. Yettel was ranked last, mainly due to poor performance on data transmission tests.
