I have a question about dual sim model. Do both sim card can work simultaneously eg. 3G like eg Xiaomi 5?
Most of dual models work with mode (2,3,4)G/2G or 2G/(2,3,4)G only.
Regards
One SIM must be in 2G. The other can be 2G/3G/4G.

Is that 2g , so no data phone only or just gprs?
I meant 2G as in phone or SMS only.

Any idea why is this limitation? I was trying to see it to LTE mainly to put that in VoLTE for calls and then realised either of the SIM only can be set to LTE.
On the XZ, I have sim1 on 4g and sim2 on 3g.

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?

Hi everyone.
Is there any dual sim phone in the market that will work in 3G network at the same time?
I am currently here in korea, where phone only works in 3G (UMTS 2100 I think) signal.
So if I have a dual sim, 3G should work on both sim at the same time.
Thanks a lot.

have you tried this phones on both 3G networks?
I read some articles regarding dual sim phone that even though it supports 3G on both sims they dont usually work at the same time, 1 in 2G and other in 3G.
Thanks.
Yes there are many types of phones came with 2 sim cards.
such as samsung & lg
but i heared about a piece that you can buy it seperatelly and insert it into the phone which make it possible to fit 2 sim cards at the same time

yah, i saw a lot of dual sim phones.. but the problem is, if it will both work at the same time in 3G networks.. since only 3G signal is supported here in korea..
I know this thread is old, but I have the exact problem right now. Dual Sim in korea, with one korean and one foreign sim card does not work!
Too bad...
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).
So how does dual-SIM work on this phone? Are both SIMs in stand-by? Can I use both for LTE at the same time? Or only on SIM for 4G and the other one for 2G - if so: can I choose independently which SIM should work with 4G at the moment, or is it fixed like Slot 1 = 4G / Slot 2 = 2G?
I'm thinking over getting this phone - coming from a Lenovo Vibe Z (Dual-SIM) and it sucks, that Slot 2 is always 2G
Both lines in stand by, you have the option to choose which line will provide the Internet.. But only one at a time... Hope this help you...

From what I've seen on several website (including: eprice.com.hk / gsmarena.com...) it seems like most people are saying only sim 1 is LTE capable...
So which one is it?
Both SIMS 4G or only SIM1 4G?
Are there maybe different models?

Got my Z3 Dual (D6633) last saturday and both sim can do 4g, but only one at a time. U choose which sim does data. Both are always on for calls and sms unless u deliberatly turn the sim off in the settings menu.
I'm looking to buy this but wanted to know if SIM 1 is running LTE can SIM 2 run in 3G but voice/text only? Both my SIMs are with Bell Mobility in Canada and they don't have a 2G network. Thanks for the help.

How's the audio processor?
How does NFC work?
What are uses for the fingerprint sensor besides unlocking the device?
How's the video quality?
Does it overheat or start to get warm during tasks?
What's your best SOT?
How easy is it to switch networks with two sims?
I have more questions but I'll relax and ask them later.

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.

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.

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.

you can not run both SIMs in 4G mode.
When you have two nano SIM cards inserted on your phone, only one card can connect to the faster 4G LTE network. The other card will connect to the 3G/2G network.

Indeed, what is already an improvement over the older phones who where 'stuck' on 2G only even when only the second SIM was activated (and so the first SIM disabled).
For the U11+ if you disable the first SIM automatically the second SIM will be able to work even with 4G+.
But it shouldn't matter since if two SIMs activated you can run the data over the other SIM. Unless you want to try VoLTE for your second SIM phone number.?
