Dual-SIM Connectivity - ZTE Axon 7 Questions & Answers

For those with the US model (although this might also apply to other models), are both SIM slots 2G/3G/4G enabled? I understand that only one SIM can be connected to data/LTE at a time, and I do see a toggle in the notification drop down to switch between which SIM provides data, but not sure if both slots are 4G capable, or if it's just Slot 1 like some other devices.

Do you have LTE menu option on your One? (not EE customers)

I am on Three UK, and although LTE is not rolled out yet, I was surprised that the LTE menu options do not appear at all. For example, why wouldn't I have this option in case I roamed to a foreign country that provides LTE to roamers.
In the network options I only have
WCDMA only
GSM/WCDMA auto
I know those on EE have another option for LTE.
Supposedly LTE and 3G SIMs are the same. In fact Three will provide free LTE access later this year automatically and without any administrative changes.
Could others confirm, if they are not on an LTE network, whether they see the LTE option on the phones network settings?
I think the phone only shows the option to turn LTE on or off if it detects LTE on your network so it should appear automatically once Three launch LTE
I agree! I decompiled Settings.apk of the HTC One and the network selection option uses RadioInfo class to determine what should be shown on the menu. In fact I can even see CDMA & EV-DO there.
Excellent. Perfect answers. Thank you. For some reason I had it stuck in my head that it was based on the SIM provisioning. I should have realised that it is based on the capabilities of the network you are currently connected to rather than a provisioning option.
I have LTE option on mine, got it on vodafone contract from p4u though the phone is sim free/unlocked.

Well done for finding that as it is buried in the P4U thread! Hopefully this thread will help others who wonder why they do, or do not, see LTE options in their menu!

My Provider is o2 Germany and there is a LTE-Option.

Hi! Could you try remove the sim card and reboot your phone and see if the LTE option is still there?

Does this mean that it will work with AT&T LTE here in the US?

No. LTE bands in the US are way different compared to the LTE bands all around the world. I'm not sure about LTE Cat 3 though.

Can't select anything. Menu is gray...sounds logical to me without a SimCard
Sent from my HTC One
In reviews I keep seeing HSPA and LTE versions, which led me to believe there are models without the chip needed for 4G.
There is no answer on this though so I'm not going to rush to buy one until I know.

Do you have any other sim(Must not have LTE on it's network) you could try inserting?
GSM / WCDMA / LTE auto
SIM-free from p4u using Vodafone Italy SIM, in an area not LTE covered
Oh crap Now that looks like a sign that it should have LTE option nomatter what sim you insert.
By the way could you tell me what's your baseband version?
Baseband version:
4A.13.3231.27_10.31.1131.05L

I tested a T-Mobile Sim.
The LTE Menu is also available here
It´s not depend on the SIM/Provider i think
I'm not showing lte version on my 3 Handset ? Which is worrying because I took out my new 3 contact for the 3 lte upgrade

Is the Moto X Play a Dual LTE device?

Hey!
Are each sim slots 4G capable in the dual sim variant? Because I have an LG G3 currently and the thing is only one slot is 4G capable, the other one is restricted to 2G (which just kills the point of a dual sim device for me).
Thanks in advance!
Nope, same as you have. 1 - LTE + 1 - GSM
To be precise: only one SIM slot at a time can be chosen as full LTE/3G/2G capable, the respective other SIM slot is then only 2G capable without any data. But you can change the selection of the slots on the fly, so it does not matter which SIM is in which slot.
That's great to hear. Which region phone do you have? Just curious.

Thanks! That is actually great. My LG G3 has two slots, but one of these is strictly 2G, I mean really LG? lol. So you cannot change it on the fly.

It can;t be enabled so far i know
To clarify, the question is about enabling 3G/4G for both SIM-cards at the same time AFAIK.
Using 3G/4G on SIM 1 or SIM 2 works, just not at the same time.

Unfortunately, thanks for the answer.
BTW. do you know phones that are using 3G/4G on SIM 1 or SIM 2 at the same time?
I thought that there is a way to enable it on Honor 7, that is why I bought the phone hehe, Thanks!

You and me both, I just made the "cutout" trick so that I can have a microSD and two SIMs at the same time but apparently my work SIM only supports 3G and 4G while my own supports 2G, 3G and 4G. I have 50 GB data on my own and 500 MB on my work SIM, so I wanted to split them that way but now I'm stuck with 0.050 Mb/s data speed on my own SIM and a microSD with a glued SIM-chip from my work phone which I don't know if I dare remove without damaging it - and if so I don't even know if I can manage to put that chip inside another phone again
Strangely enough my work SIM allows 2G roaming to Denmark (in south-western Sweden we can easily reach the Danish cell phone providers) but I don't think my employer would be happy with me racking up roaming fees of several hundred dollars per month.
I really hope there will be a fix/ROM-hack for this but I fear that it has to do with the hardware - I think it needs two 3G/4G radio chipsets (don't know what it's actually called) and only has one, just like a cheaper TV does not have PictureInPicture because it has only one receiver
But to answer your question I found a thread on another forum, but I checked the rules and I don't think I'm allowed to link it so google
"Best DUAL SIM android phone?" post 1993
and you should find it
On Chinese version, you can combine the data of both Sims to get a faster overall network speed.

A dump question. Does anyone with the plk-al10 vervion noticed that when changing from 4g -sim 1 to 4g sim 2 the phone remains for one second on 3g on both sim's? I believe that the hardware is no problem. The only restriction is by software.

Huawei mate 8 Full Active proof

Huawei mate 8 Full Active proof
Calling via sim 2 while data still working on sim 1
In this case the phone call through SIM 2 uses the GSM network.
As indicated in the specs, only one 3G/4G connection at a time can be supported.

yes but most phones will cut off data while using another sim for calling or act like the phone is off when calling and the other sim is in call

This is very good news this means that I don't have to carry around d 2 phones anymore for my business. What app is that that shows the connection speed in the notification bar up top? That could be useful.

I'm using SIM1 for Verizon, No issues. LTE speed is great and all calling and SMS features work.
For me until I placed in sim2 tray, Verizon didn't see my phone as OnePlus 6T, then they added the cdma less thing to fix sms and others.

I was using sim slot 1 for a day then my phone lost signal so had to switch to sim 2 and will keep an eye on it. Not sure why one works over the other.
