Hello,
Recently I had to use two Jio SIM (VoLTE) on my Samsung ON5 which says it is a dual 4G LTE phone. But I couldn't set LTE network mode on my two Jio sims' on the same time. If SIM-1 is LTE, the SIM-2 by default goes to 2G which makes SIM-2 as inactive ( Emergency Calls Only ). Can anyone enlighten me on this? Are there any Android phones available now in the market which enables dual LTE at the same time?
I assume my question is clear.
Thank You ,
Arus Chandran
I think this is normal, at the moment all smartphones you can use only 1 SIM LTE.

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..
Dual WCDMA

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:

Hi Phil,
Thanks so much for your email. We will forward the dual SIM issue you have identified to our internal teams for further investigation.
Best regards,

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).
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?
Can anyone let me know if the S8+ Dual Sim is 4G/3G as Australia is turning off all 2G networks.
Thanks
It's 4G/3G/2G (SIM 1) + 4G/3G/2G (SIM 2).
TL;DR: LTE/LTE.
Pretty sure that SIM 2 is GSM only

2nd sim is 2g/3g on my s8+.

Both SIMs are 3G and 4G, but you can use as 4G only one and the other one will be max 3G, or if you prefer can be 2G as well. This is not so relevant, since you switch the SIM cards for internet use (since you can not use both cards in the same time for data usage) it will change settings to 4G for the preferred SIM immediately.
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.
