I have the HP IPAC 910C and use it with T-Mobile while in the USA with no problems. However, while traveling internationally, it does not work. International roaming is activated on my account, but so far i have not been able to get a signal. I tried to use while in Japan and South Korea. According to T-Mobile Customer Service, only in Canada and Mexico is international roaming available with rep-paid accounts. Is there a programming trick or application available to over come this obstacle?
Thanx for any help!!
HTC One V GSM edition (US Cellular, Virgin Mobile) does not have the right frequencies for T-Mobile / SIMple Mobile 3G service. I have used T-Moible and SIMple Mobile SIM with GSM phone any only get Edge speeds and network.
T-Mobile officially states that 3G/4G, for the frequencies support on this phone, will be rolled out in America starting in the fall.

The unlocked GSM version could be used on Tmo USA. The US cellular and VM version cannot, as that version is CDMA and carrier locked.

sorry! Yes! GSM version of phone can work on T-Mobile, but do not expect 3G service as of now.
To get right 4G symbol look for this in system/build.prop
ro.build.target_operator=OPEN
ro.build.target_country=COM
then
Change the OPEN and COM to any variant.
Example: Should look like this when done. Then reboot.
Tmobile USA:
ro.build.target_operator=TMO
ro.build.target_country=US
AT&T USA:
ro.build.target_operator=ATT
ro.build.target_country=US
Verizon USA:
ro.build.target_operator=VZW
ro.build.target_country=US
Sprint USA:
ro.build.target_operator=SPR
ro.build.target_country=US
Cricket Wireless USA
ro.build.target_operator=TMO or use ATT.
ro.build.target_country=US
Metro PCS???
Boost Mobile???
Virgin Mobile???
I'm on Cricket Wireless USA. I didn't like AT&T's 4G lte symbol so I changed mine to TMO. Looks nicer!

Can an unlocked Samsung A50 SM-A505W (Canada version) be used in the USA with AT&T towers? In general I assume canada versions are only GSM? ie suitable for AT&T and T mobile
