The gig economy: 58% more gigabytes generated 0.4% more revenue

5G monetisation lessons from China and Korea

Tefficient’s 26th public analysis on the development and drivers of mobile data ranks 105 operators based on average data usage per SIM, total data traffic and revenue per gigabyte in 2019.

Nine months with 5G: 4.7 million subs – each using 27 GB per month

Lobbyists coined the term “the race to 5G”. If there ever was such a race, South Korea won it as unlike other markets there are – read on – many reported numbers to support a leadership claim. With 4.7 million 5G subscriptions by the end of 2019, 7% of Korea’s mobile subscribers used 5G just nine months after launch.

The subscriber take-up has been fast, but not linear. In August, September and October, when Samsung launched three new 5G smartphones (Note 10, A90 and Fold) and LG updated its V50 smartphone, 5G sales was exceptionally fast. During November and December no new smartphones were introduced and South Korea missed the expectation of 5 million 5G subscribers by year end 2019.

The FMC hoax

Without subscription growth it’s difficult for mature market operators to report service revenue growth.

Some operators – anxious to still show growth – have thus begun to regularly highlight their fixed-mobile convergence base in quarterly results presentations. It’s most often a smoke screen. Here are seven examples – of which six aren’t growth stories.

Mobile data consumption continues to grow – a majority of operators now rewarded with ARPU

Taiwan: Unlimited is so last year – Korea: 5G boosts usage

Tefficient’s 24th public analysis on the development and drivers of mobile data ranks 115 operators based on average data usage per SIM, total data traffic and revenue per gigabyte in 1H 2019.

The data usage per SIM grew for all; everybody climbed our Christmas tree. More than half of the operators could turn that data usage growth into ARPU growth for the first time a majority is in green. Read our analysis to see who delivered on “more for more” and who didn’t.

Speaking of which, we take a closer look at the development of one of the unlimited powerhouses Taiwan. Are people getting tired of mobile data?

We also provide insight into South Korea the world’s leading 5G market. Just how much effect did 5G have on the data usage?

How South Korea’s operators drive demand for 5G

Reference: Analysis and Go-to-market, 2019

Nowhere else in the world will you find as many 5G users as in South Korea. Nowhere else will you find as many 5G base stations up and running. If there ever was a race to 5G, the Korean government and industry won it.

Seeing is believing: After having dug up, read and compiled all reporting and data on Korea’s mobile business there was no other way forward than to seeing it for ourselves and interview people involved in creating Korea’s ‘5G wonder’.

We spent eight busy days (11-18 July) in Seoul to finish a comprehensive 106-page analysis – full of graphs and photos – with recommendations for European operators.

Who has the best 4G network in the Nordics?

This is our fourth comparison of the mobile network experiences in the Nordics based on performance data from Opensignal. There are more details and background is the previous (onetwothree) blogs.

This time the data is gathered from March to May 2019. The data has not been published by OpenSignal but has been shared with us through Opensignal’s analyst program.

4G availability

The graph below ranks the fourteen operators in Norway, Sweden, Denmark and Finland after how large proportion of time 4G capable devices have been connected to 4G. Opensignal calls this 4G availability.

Are fast networks fast because they aren’t used?

This blog is a follow-up on Tefficient’s recently published mobile data usage and revenue analysis of operators

    When you use a mobile network, your traffic has to co-exist with traffic generated by other users currently connected to the same cell. Your speed experience will depend on how much and what type of traffic those other users generate. It will also depend on how your operator has dimensioned that cell, i.e. how many carriers they have put up. Ultimately that depends on the available spectrum your operator has access to.

    When operators want to convince us how great their networks are, they typically talk about download speed, i.e. how many Mbit/s users on their network averagely get when downloading something from the internet. It is being supported by a number of independent network performance specialists – Tutela, Opensignal, Ookla, P3, RootMetrics – issuing country reports naming winning networks.

    These reports are actually often multi-faceted with several performance metrics, but that is often too complex to use in marketing, operators think. The simplified marketing message becomes: Speed is good – and we won.

    Here are a few recent examples:

This is what will happen in 2019


Few people think through their New Year resolutions in advance. That’s perhaps the reason to why they typically don’t last longer than the first week of February.

Making industry predictions for an upcoming year is of course something totally different. It’s hard work and no champagne. Fine analysts use twelve months to gather and refine the best ideas and to substantiate these with tons of data points – just to give it all for free to the world. It’s charity at its best.

We chip in, of course.

Our predictions of what will happen in 2019: Continue reading This is what will happen in 2019
