1 SIM @ 4G (DATA/VOICE/SMS) while the other @3G (voice) possible?

1 SIM @ 4G (DATA/VOICE/SMS) while the other @3G (voice) possible? - ZTE Axon 7 Questions & Answers

Can I have 1 sim for data & voice running at 4G, while the other sim for voice & sms only in 3G? Or only 2G supported?
Because I read at 1+3 forum that it can actually do this, so I was wondering if the Axon 7 can as well. I don't see why not, correct?
Has anyone tried this? I'm in the US, and would like to be able to run a tmobile mvno sim (4G+voice+sms) + an international sim (voice+sms) that's roaming on AT&T who will shut down 2G soon.

It's a dual 4G sim slot, so yea you can run it like that.

Go to settings - dual sim settings - network mode and on sim 2 tell it GSM only. It will keep sim 2 on 3g. Also on settings -dual sim settings you can turn off mobile data for either sim. Just put t-mobile in sim 1 and at&t in sim 2, shut off mobile data on sim 2, and tell sim 2 gsm only. Done

Thanks for the info, I didn't buy the device yet; but this makes choosing a device even harder since both can do this now (1+3 & Axon 7).
Until recently this was NOT the norm I believe, best I could find was a dual sim phone with 1 sim @ 4G while the other @ 2G only.

Doesn't GSM-only mean 2G? While both slots are hooked up for 2G/3G/4G, I think only one slot can be connected to 3G/4G at a time, the other slot goes down to 2G.
When I have my Verizon SIM in Slot1 (chosen as data connection) and a T-Mobile SIM in Slot2, using apps like LTE Discovery show my A7 connected to Verizon LTE, Verizon 1x (2G for voice calls), and T-Mobile GSM (2G), not T-Mobile HSPA (3G). When I switch the data connection source to Slot2, it connects to T-Mobile LTE and Verizon 1x (2G), not Verizon EVDO (3G).

Yes I was able to confirm LTE and WCDMA simultaneous operation
Hi! Amazingly, yeah this works...you can have LTE on one SIM and WCDMA 3G on the other (voice only). I tested this with two T-Mobile SIMs and was kind of shocked as in the past it seems like all dual-SIM phones are limited to GSM-only on one of the two SIMs, as has been mentioned above...
But...strangely, this won't work when using a CDMA SIM in slot 1 (i.e., Verizon). I have no clue why...I can definitely confirm that my experience is the same as that stated above by xtermmin - the GSM SIM will be limited to EDGE (2G only) when the CDMA SIM is active as the data SIM. But with two GSM operators yes one can be LTE/WCDMA and the other can be WCDMA/GSM. I'll confirm real quick just to make double sure but I seem to recall seeing this in the specs and was able to confirm it myself. I've attached a screenshot showing this - I have SIM 2 enabled for data as you can see but SIM 1 still shows voice-only on UMTS and thus is not just limited to 2G. I hope they fix this phone so that CDMA SIMs will have this same functionality...for now though I can say confidently that two GSM SIMs can be operated as LTE/WCDMA on primary SIM and WCDMA/GSM on secondary SIM simultaneously...really great news considering all the EDGE networks seem to be on their last leg!
EDIT: Oh - and don't mind the fact that the "Cellular Network State" is shown as disconnected - in slot 1 I have an old T-Mobile SIM just for this test - it isn't active at the moment on an account. But for demonstration hopefully it does suffice as it definitely has the phone connected to 3G service on SIM 1 while having LTE service on SIM 2. Also - I've included a 2nd screenshot to show that with Verizon LTE/CDMA on SIM 1 (shown as carrier '123456'), SIM 2 will be limited to GSM-only on T-Mo...really weird - not sure why this limitation exists for CDMA users - I think it's a ZTE bug as simultaneous CDMA 1X and WCDMA is possible with T-Mobile as the data-SIM.

Yeah for sure...I love the phone and all but I really hope ZTE will just fix these annoying CDMA bugs already...Seems like they could fix this stuff with or without Verizon's approval - from the beginning they've kind of hamstrung CDMA and I've never really understood why. Another bug I noticed was that when switching calls to the T-Mobile SIM, VoLTE has to be kicked into gear by toggling the VoLTE toggle and sometimes even putting the phone into airplane mode for a second...from what I've heard this is a unique problem to CDMA use as well.

Actually, worse than I thought...but only a bit

Thanks for the info. Has this issue been sorted out to your knowledge? We livein 2 different regions, but would only consider getting the Aussie release of this phone this month if it can seamlessly handle 4g/3g, using 2 SIM cards where both are capable of LTE. Will this work? Does it automatically switch data to SIM 2 in order to take 3G voice call, or does it temp. disable data on sim 1 (4g) to allow SIM 2 call?

Hi - I just tried this and here's what I found:
If active data is on SIM 2, a call to or from SIM 1 is possible on UMTS (WCDMA 3G) but this will terminate the LTE connection on SIM 2 for the duration of the call. However, a call on SIM 2 will not be a problem for data unless SIM 2 is on EDGE or less...on UMTS or LTE (i.e., a VoLTE call) you'll still have data during the call.
If data is on SIM 1, a call to or from SIM 2 is only possible on EDGE!!! I didn't know this! I guess SIM 2 will always be GSM-only if SIM 1 is the active data SIM. And also - you will lose LTE data on SIM 1 if you receive or place a call on SIM 2 EDGE/GPRS.
So...it looks like the situation isn't as good as I'd hoped - if 3G calling is necessary on a particular SIM card at all times, that SIM should be placed in slot 1. And it'll work well even when SIM 2 is the active data SIM. But, if you need 3G calling at all times on both SIMs, you may be out of luck.
Also, the Axon does not seem to allow you to change the data SIM in the middle of the call...in this scenario, SIM 2 was on LTE and was the active data SIM, and SIM 1 was on UMTS (calls only). I made a call on SIM 1 and then changed the data to SIM 1 to try and get 3G data during my call...but it didn't connect to data until I hung up the call...so it seems that the service state gets frozen when you make a call, in a way.
I hope this info helps...seems like kind of a mixed bag, unfortunately.

Thanks for the. That's pretty backwards by ZTE. Makes no sense. SIM 1 and 2 need to work the same way regardless of WHICH SIM had the 3G incoming call and which had 4G data active at the same time. I read the above as SIM 2 can be 2G only, or is the main SIM for 4G data....so 3G calls can be taken on SIM 1. Yep, backwards!
Axon hasn't sold me. Audio on a phone is important, but the HTC front facing speakers get easily clogged, then it looks horrendous. I'm favouring one of OP3T (as i believe this too has unlocked bootloader and root), or worst case - LG v20 or G5 dual...but neither will be given unlocked bootloaders.

So, I just tried it again and it looks like I was able to achieve a UMTS 3G connection on both SIMs even during a call on SIM 1...perhaps my initial test was in error somehow...not sure. But it looks like dual 3G is possible after all...there may be hope!

Are you sure both are running 3g, because I have had devices that always showed 3g even when connect to 2g networks, really need to test with an app the can see both sims at the same time like network cell info mini.

Yes I'm sure. I was using LTE discovery and the Settings --> Phone Status...not just the signal type indication. It can run dual 3G UMTS and/or HSPA+.

Sure thing. Just to make double sure, I just put my FreedomPop (AT&T) SIM in with my T-Mobile one and set both to WCDMA...And it's confirmed that dual 3G works fine (see screenshots below). So you should be ok! AT&T has decommissioned 2G completely so the fact that I could sustain a dual T-Mobile/AT&T connection when T-Mobile is active for 3G data should hopefully prove that the Axon 7 can get dual 3G. One caveat though - with a Verizon SIM in slot 1, slot 2 is still 2G only...So you will be limited to 2G in slot 2 if you have a CDMA SIM in slot 1 which is data-active. But two GSM SIMs should be ok. Good luck!

So Awesome, does anyone if the same is true for the new ZTE Blade v8 Pro, I sure hope so as I am looking to add both of these to my collection, Using prepaid H2O wireless for calls and text and FreedomPop LTE or Global sims for data... What would be the best setup for that data ( FreedomPop ) on sim 1 or sim 2. H20 is a AT&T MVNO

The only limitation vis-a-vis SIM 1 vs. 2 slot I know of when it comes to GSM SIMs relates to WiFi calling... You can only get WiFi calling on SIM 1. But that shouldn't matter for FreedomPop or H2O I would think so it shouldn't matter. Also, CDMA SIMs only work in slot 1 but of course that should affect you either. So either slot should be fine I'd think!

3G on O2 Exec

So my new Exec turned up today, along with a new SIM card, marked 3G.
Do I need to use this card?
My current SIM works fine in it, but Im wondering if I need to put in the new one, call Cust Services and have it enabled, or can I get the 3G service on my existing SIM?

Depends , the 3G card will allow faster internet connection- if in service area
if in stand gprs area , you get a G at top of screen
if in 3G area you get a U

Does that mean I have to use and register the 3G SIM? As far as I was aware, the SIM doesnt actually provide any functionality - its the service class your contract has?

@CPGOD
3G and GSM SIMs are different. Only with a 3G SIM can you use UMTS (3G services). Please check with O2, they may be transferring your number to the new SIM from the old - which would be a good thing if you want fast data download (max speed around 384kbps)

not true, my voda sim of over two years is now 3G enabled...

@twaddle, you're right it is possible to have a SIM that is GSM and UMTS. Did a bit of research and found SIM cards can function in GSM and UMTS modes. This has not been true for "3" network, however.

I'm not really sure the old SIM can be used to received 3G, I've just upgraded and got my old number transfer to the 3G sim, it works after a few hours. If the old one worked then why would they bother giving out the new sim?

Dual SIM again messing with my head

Hi and a happy new year everyone
I'm trying to use my tablets SIM which has rather good internet capabilities as my second SIM (SIM2). My main SIM (SIM1) is used for calls/sms.
I'm from Scandinavia. SIM1 is 3, SIM2 is Telenor.
SIM1 is being used only to call/sms.
SIM2 is used for internet.
I can't chose 4G/3G for both networks, only one.
SIM1 doesn't work with 2G network (emergency calls only problem) only 4G/3G, but that leaves me using SIM2 with only 2G, which defeats the whole purpose.
Where is the problem? Is it a phone or provider issue?

DUAL SIM LG V20 users: Please test 4G/3G capabilities and report your findings...

Hi guys,
For anyone with a dual SIM model of the LG V20, can you please do myself and others a big favour?
I need to determine the phones capabilities and functionality when it comes to dual sim capability. We know this is only dual standby, but I need to determine a few things. Can someone please answer these questions ONLY if you have this phone and ONLY if you've tested it?
1) Can a 3G phone (voice) call be received on a SIM whilst the other SIM's 4G data is in use (Y/N)?
2) If yes, does the 4G data SWITCH OVER to the other SIM to allow that voice call to come through, or:
3) Does the 4G data temporarily cut out on the "data active" SIM for the other SIM to allow inbound 3G voice call?
4) Can you deactivate test to confirm with 100% accutracy only 4g and/or 3G is being used on both SIMs?
Any help from current users (or if anyone can post a video oft he settings/functionality), that would be awesome!
Thank you
RoOSTA

Hi. Cant exactly verify this because in the Phillippines H990DS. We dont have voice call over 3G.
But if it helps, i have a viber account on SIM2s number. I use SIM1 as Data provider.
When i get a viber call on SIM2s number, it doesnt switch but instead uses SIM1s data.
But not entirely sure if that works the same as Voice over 3G

When one sim is in use the other is disabled, I think the only phone that does this is huawei mate 7, but that's 4G+2G or 3G+2G.

Not entirely. Yes, they are dual standy by...but when 4G is active on SIM and call comes in on SIM 2, it should eityhert SWITCH the data to SIM 2 to allow call to come through, or temporarily disable 4G on SIM 1 for the call to get through. See other models that dpo this:

You have the HK model, right? Makes no sense why two dozen or more other models out there with this chipset can allow 4g/3g (evenif 1 is temporarily disabled) and this new flagship doesnt.

i got the H990DS today. I have Tmo and AT&T. it has 3G standby. No matter which SIM i select in 4G the other always holds 3G.

..

here is my findings for a few days, i bought a data sim card (only internet) and added to my LG V20 as SIM2
1) yes, you can receive calls while the data is working on the second sim
2,3) in my case, when i receive a call from SIM1 (4G), the data SIM2 still connects between 4G and 3.5G, but in both cases the data is been cutted off and unable to do anything
(this was tested via hotspot the SIM2 and getting a call on SIM1, happened multiple occasions)
4) until now, SIM1 and SIM2 in my device works both on 4G (battery drainage is surprisingly holding up)(tested via switching between SIM1 and SIM2 Data connection)
one note to be considered, the data speed was very low, i called my provider and adviced me to switch to another device (portable router adviced), i switched the sim to another device (Note 3) and the net speed was signifacantly better for a while

Your answer is helpful, Silver Mask! Just to confirm, if I'm on a call on SIM2, I would not be able to use the internet on SIM1 at the same time? (e.g. if I wanted to use Google Maps with SIM1 sata while I have a SIM2 call on speaker). If I understand correctly, you're saying I can receive a call on SIM2 while I'm using SIM1 data but once I pick up the call, the data from SIM1 will be temporarily disabled?

Either disabled as an extream case, 50% of the time it switch to lower band (from 4G/LTE to 3G), even then the data feels slow, but usually any navigation app and social messaging apps doesn't get affected that much, it is just annoying

Only one sim works out of the two!?

I have an OP2 OOS Version 3.5.6. My two sim slots are also filled up with two sims. So the Problem here is Only one of the Sim works at a time. Suppose if i keep the PREFERED SIM FOR MOBILE DATA as SIM 1 , the network of SIM 2 goes off and only SIM 1 is active.Vice versa . Please help me and as far as i remember i did not configure any unneccesary things. I am just noobin these stuff.TIA

You can't use two 4G SIMs at the same time.
The SIM not set as the primary (data) SIM can only connect to a 2G network.
It's always been like this on the OP2

I mean't to say that Vodafone is 4G enabled Sim. It is not mandatory that it should work only on 4G.
Whereas JIO is a Network Where 4G is Mandatory. BTW it was working fine for the past three months without any issue.
And I even tried Having Airtel as the 1st Sim and Vodafone as the 2nd sim (Vice Versa) it doesn't work..
I thought if i Factory Reset the phone the problem would be gone, but it didn't ! Probably i have to go to a Service Centre

If your JIO SIM is the primary SIM and Vodafone have a 2G network in your location, the second SIM should be able to connect too.
If it doesn't, something isn't right.

Data with 2 sim ?

Hello,
i hesitate to take a second sim, but my interest is not to call but to have data.
Do you know if i can use data with sim 1 and sim 2 in same time, or the sim 2 is just to have another phone number and not specialize for data.
I have search, and it seems tha the sim 2 is not in LTE for the data but only GPRS/EDGE, that does not really interest me, does someone has test that ?
Thanks

4G Data works on both SIMS! The SIM where data is enabled will automatically switch to 4g/3g/2g and the other SIM will revert to 3G/2G. There is no restriction on where you wanna use 4G.
This is same with most of dual SIM phones as of now.

Thanks for the explication.

4G Data works on both SIMS! The SIM where data is enabled will automatically switch to 4g/3g/2g and the other SIM will revert to 3G/2G. There is no restriction on where you wanna use 4G.
This is same with most of dual SIM phones as of now.
