Key findings

A1 forces a tie on Video Experience

A1 and Vivacom are joint winners of the Video Experience award, in contrast to our last report when Vivacom won the award outright. This change was due to a modest 0.4 point drop in Vivacom’s score and a 0.1 point increase in A1’s. However, our Vivacom users remain the only ones who had an Excellent (75 or above) Video Experience.

Vivacom and A1 are joint winners for Upload Speed Experience

Similarly, while in our previous two reports Vivacom was the outright winner of our Upload Speed Experience award, this time it and A1 are joint winners. The shared ownership of the award was mainly driven by an impressive 1.3 Mbps (13.8%) increase in the average upload speeds observed by our A1 users.

A1’s lead on Download Speed Experience has increased, but all three operators have made impressive gains

A1 has won our Download Speed Experience award for the third report in a row. This time the operator scored a blisteringly fast 43.3 Mbps, up 9.3 Mbps (27.2%) from our last report. In addition, its lead over second-placed Telenor has increased by 2.1 Mbps to hit 6.4 Mbps (17.4%). However, both its rivals have also seen significant increases in their Download Speed Experience scores. Telenor’s rose by 7.2 Mbps (24.1%) to 36.9 Mbps, while Vivacom’s increased by a more modest — but still impressive — 5.6 Mbps (19.8%) to reach 33.6 Mbps.

A1 ties for second-place on 4G Availability

While Vivacom has now won our 4G Availability award for three reports in a row — this time with a score of 90.7% — things are getting interesting lower down the table. Our A1 users spent 83.3% of their time connected to 4G services — up 4.5 percentage points from our last report — and this was enough for the operator to statistically tie with Telenor for second place.

Introduction

Vivacom remains the operator with the largest haul of our awards — racking up three outright wins — Games Experience, Voice App Experience and 4G Availability — along with three joint wins — Video Experience, Upload Speed Experience and 4G Coverage Experience. The only award that it did not win or tie on was Download Speed Experience, which A1 has won ever since our inaugural report on the Bulgarian mobile network experience this time last year. However, as impressive as this is, Vivacom’s position is less dominant than it was in our previous report, when it won five out of seven awards outright and was a joint winner alongside Telenor for 4G Coverage Experience.

On the other hand, our Vivacom users are still the only ones in Bulgaria to observe a Good (80-87) Voice App Experience and the operator’s score for this measure of the mobile experience has risen by 0.5 points since our last report, while its rival operators’ scores have fallen slightly. As a result, Vivacom’s lead has increased by 0.7 points to 2.3 points.

A lot has happened in the Bulgarian mobile market since our previous report. Both Vivacom and A1 have launched 5G. Vivacom launched in September in all 27 district capitals’ central urban areas and along the Trakia highway, while A1 launched in November in the Bulgarian capital of Sofia and the operator claims that its 5G network supports the city’s main residential and business districts.

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 ending 29 November 2020. 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.
