Is the second SIM WCDMA 3G voice capable or is it only GSM as most dual-sim phones out there?
I can't seem to find any information on it, and this is an important piece of data for people living in countries with no 2G GSM network.
The second sim is GSM.

In other words, useless for Japan (where all voice calls go over WCDMA and there is no GSM network).

You are right in that it is useless in Japan. However, just to clarify the issue: Both SIM slots are 3g capable, but the phone forces the SIM card that is not used for data to 2g mode. Only one of the SIMs can be used for data at a time, just as you can only send texts or make voice calls through one at a time so it makes sense in any other country...
What is not clear is whether this is a Motorola decision to save battery or imposed by the chip set used or an Android OS issue. Covia Fleaphone has same issue, and provides a shortcut to switch the active SIM (active=3g enabled SIM), so it seems to be not just a Motorola decision...

I believe it has only one 3g radio in it and used by whatever Sim is being used for data So its a hardware issue

Sounds about right... It is a real pity how bad the documentation/specifications info is on dual sim phones. Make it very difficult to pick the right one, several people now claim that the Xperia M2 works with 3g on both SIMs simultaneously, but can't verify this...
At the same time I guess Japan (where I use it) is an unusual case, most places still have 2g, and Japan only recently started selling separate SIMs...

Hello,
I am looking for a phone that supports dual WCDMA. Currently my "HTC Desire 600 dual sim" provides WCDMA only on SIM1.
The SIM2 is simply GSM.
I wish a phone where also the SIM2 offers WCDMA.
Background:
due to frequent traveling in 2 countries I am using SIM1 or SIM2 respectively.
On Country1 I have Internet using SIM1, but when residing in Country2 I need to turn ON Data-roaming (of SIM1) , or interchange SIM2 into SIM1's port (WCDMA) so that SIM2 will have Access to Internet.
This is really annoying.
Any Ideas?
Thx
PS: Sorry for duplicates, I opened this thread allthough I searched and found another similar question in this Forum, dated from last year.
That question was however not answered.

i don´t no if are any phone with 2 WCDMA
lg phones have the option for wcdma on both sim settings.. you can select any one sim as 3g but other sim has to be on 2g (without removing sims out of slots).. i have used e445/e715.. do check on specific model but most probably lg must be having that on all models..

That's a good hint with LG. Manually switching forth and back to WCDMA, but without need to interchange the sims, is something I can live with.

Hey guys,
So I have the Z3 Dual, but where I live, we only get 3G network and no GSM, which brings me to my question:
Is anyone working towards a hack to allow my device to run BOTH my Telstra SIM cards in LTE mode without one reverting to GSM?
Thanks in advance,
Phil
Really? No gsm signal or 2g. I think 2g structures are the most basic one that every carrier Has. BecAuse if 3g becomes congested, the subscriber can fall back to 2g. Anyway i guess no hack is on going because of the rooting issues with this plus i think it's a hardware limitation. 2 simcards cannot use 1 modem (the 3g/4g) because that would tax a lot of battery power

There are 2 radios in the phone I'm suspecting, since both SIM's run different IMEI numbers (1 per radio) if you check in About Phone/Status and check the 2 SIMs.
So I can't see why this is a limitation.... renders the phone worthless for what I wanted it for (Work sim and Personal sim),
And yes, where I live, there has never been GSM, it was CDMA before the towers were upgraded to 3G (Central Wheatbelt is Western Australia).

When you use the first SIM with LTE the second has no signal?
I can't understand if the second sim limit is only for connection or also for 3G bands.
I mean: you can still use the second line on a 3G network only for calls and SMS without using data connection or not? The second line is limited on 2G bands?
thanks for answers I ordered a Z3 Dual 2 days ago

Correct, because the second sim drops down to GSM, which we don't have in rural Western Australia. And vice versa, set the second SIM to LTE/WCDMA and the first SIM drops down to GSM. Meaning, you cannot run 2 SIM's side-by-side unless you live in an area that has GSM/2G still.

So, you choose either SIM as your data sim. Whichever you choose, that sim runs in LTE mode and the other SIM is used for calls/sms only.
SMS and phone apps both have 2 send buttons labelled 1 and 2, so you can send messages or make calls from either SIM at the press of a button. But only 1 SIM has data active, that is the SIM running in LTE mode.
I have messaged Sony Mobile Developers regarding this, the reply was:

That's weird! If I live in a place with only 2G or only 3G network I cannot use 2 sim cards!
But I remember reading on online user manual that the 2 sims network settings are separated, right? If you force both on the right frequency?
In a few days I'll receive the phone and I'll help you with some tests

Correct, both sims wont run on 3G at the same time..
Both sims WILL run on 2G at the same time though (GSM).

How's the audio processor?
For recording videos it is very clear and loud. Haven't tested it with a hifi earbud yet. Sound from speakers are decently loud but do now sound as bassy as the HTC one or nexus 6 speakers. One thing that's great is there is NO stutter when listening to audio with the front facing speakers and changing from landscape to portrait (as happens on the nexus 6)!
How does NFC work?
NFC is the same, tap on something and bam, nfc'd.
What are uses for the fingerprint sensor besides unlocking the device?
So far under android 5.1.1. Just to unlock the device. Once marshmallow comes out I'm sure more uses for it will follow.
How's the video quality?
Video quality is amazing. Colours have a nice balance to them. I turn off the x-reality engine.
Does it overheat or start to get warm during tasks?
Warm when charging and doing some serious downloading or installing a **** ton of stuff. Not hot at all. Haven't recorded 4k video. Will wait for the new camera app to be pushed out before I make any judgments.
What's your best SOT?
So far after one day of use 3.5houra SOT at 75% brightness constantly.
How easy is it to switch networks with two sims?
Seems fast enough. Just pick which for LTE and which for gsm voice. One thing of note... you cannot use LTE simultaneously on the z5 Dual. You can have one as LTE and one as gsm (2g) for voice and text only (so basically Rogers). Calling when one on sim and if someone calls you on the other sim, it will forward to your voicemail.

When you say "just pick which for LTE and which for voice", do you mean you can actively pick which SIM is using LTE Data via the settings app, or do you have to physically switch out the SIM cards in the actual device itself? I currently have a Dual SIM Phone but to pick which one gets Data, I have to physically remove and switch the SIM cards, not through the system's settings.
You can switch them actively on the go via the settings. Sucks you can't use LTE for both sims at the same time though, but I guess that would be a huge battery drain
got the single sim - E6653 on Rogers in Vancouver, so fast!!!
I have a follow up question on the dual sim support. So you mentioned one SIM supports LTE and one will support GSM/2G.
So is the second SIM is only 2G or can you get 3G/HSPA support?
Also what happens if you get a call on the LTE SIM? Will the phone CSFB to 3G on the LTE SIM's network to accept the call (since no VoLTE support)?
Hope that makes sense.
I was considering the dual sim model since I have two SIM's myself. One for work and one for personal. Both are voice and data LTE but on separate networks (AT&T and TMobile). If i'm hearing you right then there isn't much advantage for dual sim in N. America since 2G voice isn't any cheaper than the 3G or LTE...in fact the 2G networks kinda suck now since all the focus is on LTE and getting to VoLTE.

As far as I am aware, it supports gsm network (most likely 2G only). I don't have data on my 2ND sim so I'm not sure if it supports 3G data, I doubt it though.
If I receive a call on the LTE sim, it reverts to hspda yes. No VoLTE on telus AFAIK.

Just time it. Quick charge is usually 0-100% in about 1.5 hours. Which charger did you get?

Does the Sony or Android UI tell you which network you are connected to on the primary line? In screen shots it seems like it just shows signal strength on both lines. I'm curious if it says LTE, 4G, H+ or H. My ATT service switches quite a bit here in Houston so sometimes I force the phones to 3G only in areas where reception is awful.

Capture the screenshot (feel free to cover your IMEI there).

My Xperia Z5 Dual will got the following message and forced to restart when I have changed "Preferred network type" in settings--->More--->Mobile networks--->SIM1/SIM2, or even I have replaced another SIM card. (I have turned my phone off when replacing SIM card.)
Your device will now restart to be optimised for your service provider.
This is very annoying and anyone knows how to fix this issue?
Much appreciated!

I stand corrected, its 2G standby! That being said you can switch the primary data line to SIM2 to LTE/HSPA which forces SIM1 to 2G :crying::crying::crying:

I've asked the same question to a Xperia rep. when I've purchased XZ dual in Hong Kong.
Both slots are 4G speeds, but if both slots are in use; highest speed of one slot is 4G and other limited to 3G max
They don't have 4G/4G support yet...
Hope this helps.
Well I was going to start a new thread, but this seems like the correct place to ask:
So if I have one sim dedicated to calls/text and a second sim just for data, the phone should operate the same as if I had only one sim which can do both phone and data?
Also if both sims are capable of handling calls, can i deactivate the phone of one sim card but keep the data active?
I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...
If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.
Sent from my MHA-L29 using Tapatalk
3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.
4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.
