Key findings

T-Mobile and Vodafone share the crown for Download Speed Experience

In our first report on Mobile Network Experience in the Czech Republic, Vodafone was the sole winner of the Download Speed Experience award. However, this time T-Mobile managed to catch up with the previous winner and forced a statistical tie against Vodafone. This resulted in a joint victory for both operators, with the average download speeds experienced by our users hitting the 40 Mbps milestone. Our users on O2’s network saw lower average download speeds of 31.4 Mbps — 8.6-10.6 Mbps behind the joint winners.

Vodafone defends its video, games and voice app experiential awards

Vodafone remains the sole winner of all three of our experiential awards — Video, Games and Voice App Experience. The operator is an outright winner of these awards for the second time in a row, while O2 and T-Mobile are statistically tied for second place across all three categories. Notably, all operators were separated only by 2.1 points (on a 100-point scale) for Video Experience and 2.4 points for Voice App Experience. Vodafone was the only operator in the Czech Republic to place in the Excellent category (75 or above) for the Video Experience award, which means a very consistent experience across all users, video streaming providers and resolutions tested, with fast loading times and almost non-existent stalling.

O2 and T-Mobile catch Vodafone to force a three-way draw on 4G Availability

4G Availability shows the average proportion of time Opensignal users spend with a 4G or better connection on each operator's network. This time, we saw an intense battle for this award, which resulted in a statistical tie between all three Czech national operators. O2 and T-Mobile join the previous sole winner Vodafone in a three-way statistical tie and therefore share the 4G Availability award. All Czech national operators scored above 90%, which means our 4G users were, on average, connected to 4G or better services on their network more than 90% of the time.

O2 wins 4G Coverage Experience again

Opensignal’s 4G Coverage Experience is a measure of how mobile subscribers experience 4G coverage on an operator’s network. Measured on a 10-point scale, it analyzes the locations where customers of a network operator received a 4G signal relative to the locations visited by users of all network operators. O2 claims this award for the second consecutive time, with a score of 9.6 points — 0.2 points ahead of T-Mobile and Vodafone.

Vodafone outright wins the Upload Speed Experience award for the second consecutive time

Our users on Vodafone’s network enjoyed the fastest average upload speeds, clocking at 15.6 Mbps. This was 1.3-2.1 Mbps ahead of what our users on T-Mobile and O2 experienced — and both these operators are in a statistical tie for second place. Upload speed is key for mobile internet users, as it affects their ability to share content online, such as photos or videos, and supports real-time communications services.

Introduction

In our second report on mobile network experience in the Czech Republic, Vodafone wins four awards outright and shares two joint wins with its competitors. Vodafone remains undefeated for our three experiential awards — Video, Games and Voice App Experience — and defends its title for the Upload Speed Experience. However, T-Mobile forced a statistical tie against Vodafone for the Download Speed Experience. Both T-Mobile and O2 are in a three-way statistical tie for 4G Availability together with its previous winner, Vodafone. O2 keeps hold of our 4G Coverage Experience award.

Switching off 3G, or 3G sunset, is becoming more common in European markets and the Czech Republic is no exception. O2 Czech Republic intends to gradually close its 3G network and aims to complete the shutdown by the end of November 2021. The operator will use its 3G spectrum for 4G services, the move will enable further development of O2’s infrastructure and the roll-out of its new 5G network. O2 plans to cover the entire area of Prague by the end of March 2022, while deploying a 5G network in other cities.

Four Czech operators — O2, Vodafone, Nordic Telecom and PODA — requested telecom regulator CTU, to change spectrum allocations in the 5G-capable 3400-3800 MHz range, to make it easier and more efficient to deploy 5G in that band. CTU launched a public consultation on this topic that ended at the end of June 2021.

In this report, we examined the mobile network experience of the three main mobile network operators in the Czech Republic: O2, T-Mobile and Vodafone, over the period of 90 days between May 1, 2021 and July 29, 2021, to see how they fared. 5G measurements contributed to the overall scores.

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.
