The era of price hikes for budget SIMs is upon us—UQ Mobile has shocked its old plan subscribers with a notification of a 220 yen monthly increase.

Starting November 1, 2025, UQ Mobile will revise the monthly fees for its "old plans," which are no longer accepting new sign-ups, by increasing them by either 110 yen or 220 yen, rather than a uniform rate. Simultaneously, the monthly data allowance will be increased by +1GB or +2GB, respectively. For example, the "Komikomi Plan +," "Tokutoku Plan," and "Kurikoshi Plan M/L +5G" will see an increase of +220 yen and +2GB, while the "Minimini Plan" and "Kurikoshi Plan S +5G" will increase by +110 yen and +1GB. The current "Komikomi Plan Value" and "Tokutoku Plan 2" are not affected. The reason for the revision is due to "the rising costs associated with recent inflation," and the changes will be automatically applied without any need for procedures. Additionally, after the revision, a special offer will be available for old plans, reducing the "au Starlink Direct Exclusive Plan" from 1,650 yen to 550 yen per month. The parent company, au, is also raising its major plan prices by up to 330 yen in August 2025, with indirect cost increases such as the universal service fee rising to 3.3 yen (from July 2025 usage) contributing to the background. Although budget SIMs are not entirely in a "price hike mode," the automatic revision of old plans and the effective increase in charges could become the "new normal" moving forward. It is advisable to "review plans," "visualize data usage," and "compare with other companies" before the revision.
