Hi
I have a problem with my xperia z3, I am not able to set both sim to use LTE.
If i set sim 1 to use LTE, sim 2 will change to GSM.
If i set sim 2 to use LTE, sim 1 will change to GSM.
Is this right??
Can I have both sim using LTE since both telco provide LTE service.
Seems normal. Only one LTE at time, another user is worried about same issue (not have a Z3 dual, going to buy one)

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.

I am actually not quite familiar with this brand, have you tried this model and will both work on 3G simultaneously?

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...
Do you know a phone that has dual sim and has support for 3G for one sim and 4G for another sim simultaneously ?
Or 4G support for bought sims ?
And it should be available in Europe
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:

Thanks for infos!
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).
Iwas looking to buy a Z3 dual sim D6633. I have w bell mobility sims and they only support 3G they dont have a 2G network. Would the Z3 allow sim 2 to be on 3G for voice/texts only and Sim 1 on LTE?
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.

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.
