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

I posted this in the Networking thread too.
My Husband recently bought a Samsung Galaxy S4 mini. Come to find out it's on CDMA network. I have unlocked the phone and rooted it. I need to know if it is possible to switch this cdma phone to gsm network?

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!
