When it comes to Rakuten Mobile, there is always the worry of whether the signal is good. Because of my job, I travel a lot, so I would like to report on the signal conditions of Rakuten Mobile from all over Japan.
This time it's Hakata Station.
As this is SoftBank's headquarters, the area is likely to have strong SoftBank signals 📶.

There are two types of survey methods.
Part 1: Opensignal's simple signal check app
Opensignal is an independent global company that analyzes consumer connectivity experiences and can provide you with the upload and download performance scores for the major carriers in your location, as shown below.
The location is Hakata Station where the author is located.
Sorry, I forgot to take a screenshot.


As a result, Rakuten Mobile was ranked last in downloads and the best in uploads. It's neither good nor bad.
Step 2: Check the number of signal bars on your smartphone screen.
Next, let's check another thing. I use dual SIM and have a main line and a sub line for the Internet.
Main line: Rakuten Mobile (signal 📶upper row)
Sub-line: SoftBank (signal 📶lower row)
The screen will be the same as before
Please check the number of signal bars on the top right 📶👇👇👇👇

This time, both Rakuten Mobile and SoftBank had the maximum number of signals, resulting in a draw.
What do you think? I didn't feel any particular inconvenience at Hakata Station.
