Skyrocket 3G not working well in Hong Kong - AT&T Samsung Galaxy S II Skyrocket SGH-I727

My Skyrocket always has a lower received 3G/WCDMA2100 signal than my Galaxy Nexus even they connect to the same 3G/2G network in Hong Kong. At some places, my Skyrocket cannot make any call on 3G but would not switch to 2G/GSM900/1800, whereas my Nexus can make prefect 3G calls.
I have tried different versions of ROM/radios. Is this a hardware or radio firmware problem??
Anybody has used Skyrocket in Hong Kong, Singapore, China ..... Asia countries??? What is your software version numbers please??
Desperately need help!!!

[Q] Will Asian HTC Sensation work in Canada Wind/Mobilicity?

Hi, just wondering before I purchase this phone.
If I buy an HTC Sensation from Hong Kong, given that it supports 1700 frequency (I don't know if it does though, so if someone can clear this up it would be great), will it work on Wind or Mobilicity in Canada? A friend told me that it might not work because Hong Kong's HSDPA+ is different from Canada's and it might not be compatible.
Thanks!
Yes. I am using an Asian WWE AWS phone on Wind.
hong kong's HSDPA+ actually isnt different from canada's, both AWS networks were built by huiwei, and use the same hardware/standards
Thanks guys. But can anyone verify whether the Asian HTC Sensation does support AWS?

G955N signal unstable in HK after upgraded

Hello all
Have anyone faced an issue that G955N LTE signal unstable after upgraded?
I bought the Korean version in HK with CMHK carrier, when using stock AQDB firmware it went fine, after upgraded LTE signal always no data traffic almost every min., (sometimes signal dropped too and connect)
I also tried installing customs ROM and even flash to G9550 CSC but same.
Any solutions? or actually G955N 4G band is not suitable in this carrier?

Using Dual Sim phone in Australia

Recently, I've started to have random issues with phone calls not coming through to my phone. I noticed that my primary SIM with LTE has noticeably worse service than my secondary SIM. Both SIMs are on the same network, but the issue appears to be LTE-related. Whichever SIM I use, once connected to LTE the service drops at least 2 bars lower.
This is a Singapore stock Dual SIM phone with Malaysian firmware (for more reguar updates). Do I need to update the modem firmware to be more compliant with Australia's networks? Or is this something inherent to the phone?
Thanks for any help!

I never used the Malaysian firmware but I can tell you that I've had the Russian one before and my lte signal was pretty bad in Canada. I've reflashed with the Saudi Arabian fw and I'm seeing significant improvements.

I'll have to give it a shot and see how it goes.

Question Help - LTE problems with Snapdragon (US version) in Europe

Hi Everyone,
I've searched for hours in the forum but no straight forward answers to this simple question:
I would like to buy the snapdragon version from wondamobile (Hong Kong).
I currently have a Note 10+ Snapdragon US version (sm-n975u1) and have many problems with LTE loosing signal very easily compared to exyons verison. It's really a hassle becuase the phone loose signal during phone calls and music stream while driving or walking.
I'm located in Italy but the same problem happended in France
Does the Hong Kong version have the same issue? anybody who imported snapdragon form Hong Kong already?
