Optimal Dual SIM Combinations [8] ” UQ Mobile x LINEMO “

Prepare for unexpected communication failures! The ultimate combination for stable communication and excellent coverage!

To prepare for communication failures, combining “different networks,” such as UQ Mobile (au network) and LINEMO (SoftBank network), is effective.

Using different networks in conjunction with one carrier offers greater fault tolerance than relying solely on a backup of the same carrier’s network. Even if one network fails, you can switch to the other and continue communication.

Main line: UQ mobile

UQ Mobile is a sub-brand of au, and because it uses au’s main network (4G/5G), it offers excellent communication stability and coverage. Many users report minimal signal drops depending on the time of day or area.

Whether you use a lot of data or not, if you’re unsure which plan to choose, this is the one!

Up to 5GB: ¥2,680 (¥2,948 including tax) *A discount of ¥1,100 (including tax) per month applies when using up to 5GB.

Over 5GB to 30GB: ¥3,680 (¥4,048 including tax)

Unlimited Calling Light [Option]: ¥880 (including tax) per month. Unlimited domestic calls of 10 minutes or less per call, 24 hours a day.


Secondary line: LINEMO

Affordable and Simple Pricing
LINEMO offers a Mini Plan (from ¥990/month) and a 20GB plan, with clear and affordable pricing. It helps lower your monthly fixed costs.

LINE Gigafree: Unlimited LINE Usage
You can use data communication such as chat, voice calls, and video calls on the LINE app without consuming your basic data allowance.

We recommend using this number for LINE.
However, if your mobile data communication is “UQ mobile” (main line), LINE calls, chats, and image sending will consume UQ mobile’s data allowance.
On days when you use LINE frequently, you can save data by switching LINEMO to data communication.

Best Plan ~3GB: ¥900 (¥990 including tax)
