Will Unlimited 5G Data Plans Reduce Wi-Fi Usage?

T-Mobile believes customers of its unlimited usage  5G service are starting to rely on the 5G network and not shifting access to Wi-Fi. 


In mid-December 2021, T-Mobile said “13 percent fewer MAX users are connecting to Wi-Fi, 80 percent more are hosting a Wi-Fi hotspot and their hotspot usage is up 20 percent on average during the weekends.”


That is not unexpected, as the leading mobile service providers shift users to higher-priced unlimited usage plans that eliminate the financial incentive to switch to Wi-Fi. 


In 2021, Wi-Fi represented as much as 46 percent of total global end user IP traffic, according to Cisco. Mobile networks supported about 17 percent of total end user IPtraffic in 2021. Fixed networks delivered nearly 53 percent of internet traffic in 2021, compared to the share delivered by mobile networks, at about 21 percent, Cisco says. 


Usage varies by market. In India, about 98 percent of total internet access uses a mobile device. Globally, mobile users consume as much as 60 percent of total data on fixed networks (Wi-Fi).


In recent years, U.S. mobile customers have spent about half their connected time on Wi-Fi (fixed network), not the mobile network


By 2023, U.S. mobile users might offload as much as 75 percent of data consumption to fixed networks, some in the Wi-Fi community believe. But much hinges on how consumers behave when they have unlimited usage plans, which might reduce Wi-Fi consumption.

It might also matter how mobile tariffs are shaped. Home broadband allows multiple users and devices to share a single account. As mobile plans move towards unlimited usage, and if multi-user plans create incentives for smartphones to remain on the mobile network all the time, and if indoor reception is not an issue, then more users might remain connected to the mobile network all the time. 


An Ericsson study found that 5G customers on unlimited-usage plans reduced their reliance on Wi-Fi. In markets such as the United States, Taiwan, Switzerland, Finland and South Korea, where a higher proportion of 5G users are on unlimited plans, 22 percent have decreased their home Wi-Fi usage, while 14 percent have stopped using Wi-Fi after upgrading to 5G, Ericsson found.


Older data (from 2016) shows the same pattern. A 2018 analysis suggested that unlimited-usage mobile data plans decreased use of Wi-Fi by about eight percent.

Motivations can change over time. In the 3G era, users switched to Wi-Fi because Wi-Fi was faster than 3G. In the 4G era, when 4G was generally faster than Wi-Fi, the switch to Wi-Fi made sense because it reduced mobile data plan usage. 


The 5G pattern is not so clear, at least not yet. Assuming the financial benefit of switching to Wi-Fi is not present, then speed, signal stability or other advantages could be decisive.
