Softbank 007z and C01HW don't have GSM mode ?

Recently, I traveled on business to Philadelphia, USA.  I brought my sim-unlocked 007z and C01HW, wifi mobile routers.  My 007z was flashed by 007z for BIZ firmware.  C01HW is a sim-free model originally outside Japan.  As far as I know, it was not obvious whether 007z and C01HW were usable in GSM area or not.  I tried them with T-mobile SIM.

T-mobile USA is using 3G of 1700/2100MHz (AWS), which is of course not supported by 007z nor C01HW.
Softbank 007z and C01HW recognized T-mobile sim but displayed "No Service".  I check every settings on the web-based utillities but they never connected T-mobile USA.  Therefore, it is supposed that 007z and C01HW don't support GSM mode as well as AWS.

My ISW13HT could connect T-Mobile USA at most EDGE speed.

ISW13HT HTC J on FOMA plus area

HTC J (ISW13HT), japanese custom model of HTC valente, is my favorite smartphone.  It has been developped to get ROOT, S-off, and SIM unlock (link in japanese).  Recently, I'm using HTC J with Docomo MVNO data-only SIM (iijmio).  In previous android versions,  the problem of "cell standby" battery drainnig would occur in a data-only SIM according to here.
However, the improved fix of HTC J was already disclosed in here (japanese).

In addition, the special modification for HTC J to catch FOMA plus area (W-CDMA 800MHz band XIX) was also disclosed in here.  I adapted these mods to my HTC J with some difficulties.

Yesterday, I traveled to Hokkaido on business.  Then , I comfirmed the above mentioned mods worked well (connection was established on FOMA plus area and antenna pict was displayed).
