Key Findings

Telenor draws level with Vivacom on 4G Availability

Telenor and Vivacom are joint winners of the 4G Availability award as our users on their networks did not observe a statistical difference between their scores — 87.8% and 87.1%, respectively, with both beating A1’s score of 83.4%. Vivacom had outright won the 4G Availability award ever since the first report on the Bulgarian mobile network experience back in January 2020. All three of Bulgaria’s operators remain below the 90% mark for 4G Availability — which measures the proportion of time that our users were connected to 4G or better.

Telenor and Vivacom put on a burst of speed

Our Telenor and Vivacom users observed significant increases in their average download speeds since the previous report. The operators’ Download Speed Experience scores rose by 5.7 Mbps (14.3%) and 5.8 Mbps (13%), respectively. Despite our A1 users not seeing a significant increase in their average speeds, A1 and Vodafone are joint winners of the Download Speed Experience award for the second time in a row.

All three Bulgarian operators jointly win the Upload Speed Experience award

Our Bulgarian users did not see any statistical differences between their average upload speeds on the three national operators’ networks and as a result, A1, Telenor and Vivacom are joint winners of the Upload Speed Experience award with scores ranging between 11.9 Mbps and 13.1 Mbps. In the previous two reports only A1 and Vivacom shared the award.

All Bulgarian 4G users connected to 4G in at least seven out of 10 locations

A1’s 4G Coverage Experience score has now hit the seven-point mark, although this improvement since the last report was not statistically significant due to large confidence intervals. However, because Telenor and Vivacom’s scores were comfortably above this threshold, our Bulgarian 4G users connected to 4G in at least seven out of 10 locations they visited on average regardless of their choice of operator.

Introduction

Our Bulgarian users continue to see incredibly hard-fought contests across the majority of measures of the mobile network experience. In fact, this time, not a single operator succeeded in winning an award outright — as Telenor and Vivacom are now joint winners of the 4G Availability award, previously held solely by Vivacom. Vivacom has the strongest showing, as it is a joint winner in all seven categories. However, it used to dominate the awards table to a much greater extent — back in the June 2020 report, it won five awards outright.

In this report, we’ve analyzed the mobile experience of our Bulgarian users across all three national operators — A1, Telenor and Vivacom — over the 90 day period starting on September 1, 2021 and ending on November 29, 2021. Our results include measurements from 5G devices.

Opensignal measures the real-world experience of consumers on mobile networks in the places they live, work and travel.

We continually adapt our methodology to best represent the true experience of smartphone users. Therefore, comparisons of the results to past reports should be considered indicative only.

For every metric we calculate statistical confidence intervals indicated on our graphs. When confidence intervals overlap, our measured results are too close to declare a winner. In those cases, we show a statistical draw. For this reason, some metrics have multiple winners.

In our bar graphs we represent confidence intervals as boundaries on either sides of graph bars. In our supporting-metric charts we show confidence intervals as +/- numerical values.
