Hi Folks ,
the S Duos has two SIM-Cards and both work with WCDMA but not at one time. At one time only one of the SIM-Cards can be in a 3G net and the other could only do GSM.
Does anybody knows if this behavior is a hardware or software issue. My Galaxy is rooted, so software issue should be resolvable.
The background is: I want to have a dual SIM Phone for Japan. Japan only supports 3G - no GSM. So my hope is that the Galaxy S Duos could work with both SIM-Cards in 3G.
Best regards and Thanx

Hi, just received my Honor 4X in China. It's a nice phone with incredible features for a low price. As I travel a lot between China and Germany I bought the FDD version.
What I did not realize (Chinese description) was the fact that SIM1 is locked for China Telecom. SIM2 accepts my German SIM but only with 2G.
Any Idea how to unlock SIM1 so that I can use LTE with my German SIM card?
Thanks for your input
Hi,
I can't find anything relevant on XDA for your device and issue. You will need to ask for help here,

Hello, and thank you for using XDA Assist!
The 920i is the international model, and thus misses Band 4 (1700mHz) which is used by the USA GSM operators (AT&T, T-Mo, MetroPCS, et cetera). This means you won't get 4G LTE with this device.
Also, if trying with T-Mobile, they alos use 1700mHz for HSPA (3G), a frequency your device does not have either. So unless T-Mo still supports 2G (I remember a planned phasing of that out at some point), your device will not work with their network.
AT&T on the other hand, uses 3G 850/1900 frequencies, so you should be okay.
At any rate, I could be optimistically wrong. So, please create an account, so you cna post in other forums, then either post in the above linked thread, or in the S6 general help thread:

Hope this helps, and good luck!
