This short survey report from MMD Labo looked at the Spring 2021 mobile service provider situation.
The full survey is much more detailed, so if you want a deep dive, please visit their site and purchase the full survey results.
Note that ahamo is docomo’s cheap plan, povo au’s, and LINEMO SoftBank’s, each costing just under 3,000 yen all-in for 20gb data and 5 minutes free per phone call.
In Q2 I’m not surprised that Rakuten is the most-investigated, as they have been flooding the airwaves with exceptionally irritating adverts offering completely free service for the first gigabyte of data port month.
