I checked the service area of ​​EMOBILE in Osaka

On March 31, 2007, we newly entered the mobile phone businessNew service of EMOBILEStarted but we could lend the product version of "EM · ONE" corresponding to this service this time.

Unlike evaluation machines that I was able to lend last time, HSDPA communication function can also be used as a product version, so I brought "EM · ONE" immediately, I tried to confirm the area in the main part of Osaka. This is an area report along the main line "Subway Midosuji Line" which can be said as the aorta of Osaka this time.

Details are as follows.
I checked this time between "Osaka municipal subway Midosuji line" Shin Osaka "~" Tennoji ". Between "Shin Osaka" and "Tennoji" there are major terminals in Osaka such as "Shin Osaka" connecting the Shinkansen, "Umeda" "Namba" "Tennoji" connecting with private railways and JR, Yodoyabashi "and other entertainment districts and entertainment areas such as" Shinsaibashi ", so I decided to check this area.

I used the same white "EM · ONE" same as last time.


Refer to the following link for detailed route map.

Subway / Neutram route map

The radio conditions at each station are as follows.

Shin Osaka (ground station)... 2 to 3 antennas. Good.

Nishinakajima Minami (ground station)... 2 to 3 antennas. Good.

(From here to underground)

Nakatsu... Outside the service area

Umeda... Outside the service area

Yodoyabashi... Outside the service area

Honmachi... Outside the service area

Shinsaibashi... Outside the service area

Namba... Outside the service area

Okuni Town... Outside the service area

In front of the zoo... Outside the service area

Tennoji... Outside the service area

The underground station is annihilated, it has become a terrible result. For users using the subway, is not it quite severe? Even if it is barely possible to communicate in the vicinity of the ticket gate, it will not be possible to communicate as soon as you get off the platform.

Umeda station ticket gate. The radio wave is unstable also in this neighborhood.


Namba station ticket gate. There is an underground shopping center called "Namba Walk" in the east and west of this station, but it was out of the service area.


Tennoji station ticket gate. Communication is barely possible in the vicinity.


The subway Midosuji line is the aortic line of Osaka, and it seems that many users want to use EM · ONE in the subway because the office streets and downtown streets are lining along the line. Is it necessary to expand the area as soon as possible?

Also, just to be sure, when I walked down the underground shopping areas of Umeda, Namba and Tennoji, there was almost no place for radio waves. Especially since Umeda is an underground shopping area with the largest scale in Japan, it is desirable to respond quickly.

Although communication was difficult in the underground shopping street, it was almost communicable around the above ground stations. However, every time when entering the shadow of some buildings, the number of antennas frequently varies between 1 and 3 violently and received the impression that the radio wave environment is not stable compared with other mobile phones.

By the way, according to the following link, roaming with NTT docomo will be started in conjunction with the start of the voice call service in March 2008, and the area will be able to cover the whole country at a stretch, so I will try it there It might be nice.
