GSM service is dominant in Taiwan, but international roaming service with Japan
is not available because GSM service hasn't been launched in Japan yet. Therefore,
a demand for international roaming service using other mobile technology, for
example PHS, is getting bigger and bigger in Taiwan.
Under the agreement between FITEL and DDI-POCKET, after May 15, 2002, users of
the PHS phones with international roaming function provided by FITEL are able
to use their phones in Japan as well as Taiwan. In short, they can receive DDI-POCKET's
Japanese nationwide PHS network service with the same phone number (One Handset
Features of this service are as follows.
(1) One Account Double Number Service
A phone call made in Taiwan to the users of FITEL's PHS phone with international
roaming function will automatically be forwarded while they are staying in Japan
and further, the same rate as DDI POCKET is to be applied to them for their calls
made in Japan using DDI POCKET's phone number (070-xxxx-xxxx) assigned to their
phone at the time of subscription so that no additional charge is required as
with trombone rooting (Note).
Single billing will be made by FITEL even for international roaming users for
(2) Data Communication Availability
The same as in Taiwan, data communication service with 64 Kbps PIAFS is available
in Japan as well.
This is the first case in the world for the PHS international roaming service
and DDI POCKET plans to launch a similar service for roaming to Taiwan as well
for its Japanese users in the future.
(Note) Trombone Rooting:
Usually international roaming will be made through a switching office that contains
original subscriber information (phone number etc.) even for a short-range call
within the same roaming area etc. due to the limited roaming conditions. Such
roaming system is called as "Trombone Roaming" as its communication route resembles
to the shape of the trombone.
