[Q] dual SIM question

Quick question for you dual SIM users.
Does the Moto G2 support 3G on both Sims?
I intend using two three SIM cards, but they only support 3G. So if SIM two is only working on 2G it would be no good to me.
Thanks

The data connection is for one sim only, you get to choose if you use data on sim one or two, data is automatically change sim, for example from 3g sim1/2g sim2 to 2g sim1/3g sim2

Thanks, I'm with you. So with my two three Sims there would be only one SIM on at any one time.
I have I signal SIM moto g1 now, and if I switch to 2g only the three SIM no longer works.

Both Sim work at the same time while I'm using 3g in any Sim.
Data is available only for one Sim at a time, but the change is really fast and automatic when you select which Sim to use for data
I use mine with same carrier, it uses the 850mhz band.
Remember this phone is dualsim standby, it means if you're using voice in one Sim the other is unreachable.

Yes just on most networks if you are on 2G the sim still works. On three they don't.
A three SIM won't work on 2G no calls text or anything.
So even with both sims in standby only one would receive calls, am I right?
Only way to receive calls on either SIM (from standby) on a moto g is if at least one SIM works on 2G?

I've own two dual sim phones s4mini (lost it) an this moto g 2014, both are stated as dual sim standby, I haven't notice any difference in the way they handle simcards/data/voice.
On both phones I've use same carrier/numbers, one is personal (same number for 10+ years) the other from work (same number for 5+ years).
I've never missed a call on either Sim.
Even if I'm downloading something I can receive calls and text messages on that sim the download stops but my phone core functionality is still a phone for both simcards with any combination of data in 2g/3g or 2g/2g.
I'm never going to carry two separated phones, for me is enough the dualisim standby functionality.
For you is a pain that your carrier don't support 2g network any dual sim standby won't work, you need a dual sim phone with two separate modems

Thanks for confirming that, only other thing I can do is use one SIM and activate call divert on the other number.
That's the main drawback with three only supporting 3G/4G

Cell signal keeps reverting to 3G

Hi,
So I'm having an issue keeping an LTE signal. I use straight talk with at&t and I can get LTE if I turn the radio on/off, but it will always switch itself over to 3G at some point in the same location. There are apps that can force it to do LTE only which works, but I can't make or receive voice calls over LTE.
Does anyone know how to fix this? This never happened on other phones on the same network. In my specific location I get 2-3 bars of LTE and 4 bars if switched to 3G. I guess it wants to keep using the better signal.

Also at home where I have full signal LTE and H+, it will choose H+ over LTE.

Had same problem. Switched sim slot to the other. 4g again. Try IT?

Did you try different APN settings? I'm guessing you already checked the preferred network option.

APN settings are good and I can get LTE if I flip the radio on and off...it just always wants to revert back to 3G at some point. Same thing happens in sim card slot 1 or 2

Which rom are you on? I remember there's a specific rom that has a bad modem file. Trying updating to the latest version.

Maybe you can solve it by going to APN settings and set APN protocol -> IPv4 and APN roaming protocol -> IPv4 . That worked for me. I had the same issue.
Or try IPv4/IPv6. That's network related and maybe IPv4/IPv6 is correct for you.
I have to set it every time I flash EU or EPIC rom.
Good luck.

did you ever figure this out?
I'm having a similar problem on a Note 4 Global. Only it switches to 3G for a voice call and never switches back.

Firmware update?

I've updated it, and it's all the same. Once in a great while it will switch over to LTE on its own, but 99% of the time it will just sit on H+ forever even though I know the LTE is fine wherever I go.
I guess this is just how it's going to be.

I finally fixed this by wiping everything in twrp and flashing a newer version of the global stable rom. LTE works fine now, and it doesn't stick on H+ when I make a call anymore.

That's interesting. I guess Xiaomi fixed the bug in one of the releases. I wonder why you had to wipe everything though. What if we try to flash the latest modem. Is there a link to that? Would that work?

Would modem be the same as firmware? There's a thread on here that has those. None of them did anything for me.
My LTE problem is isn't fixed after all I guess. Once it loses LTE, it still never reconnects to it on its own and goes to H/H+ forever.
I guess the only thing that I've fixed is that it actually switches back to LTE after a phone call.

N950F/D gets LTE with 1 sim but adding 2nd sim wont go jigher than H+

Anyone else has e this issue?
I put 2 ATT Sims in my device. When only one is installed it shows 4G (LTE) but if I put the second one in, it drops to H+, even when settings haven't changed.
Anyone know why?

Coz its a 4g + 3g stand by phone. Only 1 sim can active on LTE while other on 3g and vice versa.

Thanks s correct. But it's not getting 4G when there 2 Sims. It drops down to H+ as Soon as a second sim is inserted. With one removed it gets 4G.

Go to the simcard manager and tap the simcard you want 4G on, and check if network mode is set to 4G/3G/2G (auto connect)

How to force 4g LTE on sim 1 or sim 2 as needed?

I am using the dual sim Exynos version of Note 9 and want to be able to force 4g LTE on either of the two sims as needed.
Can someone please advise how to do this on an unrooted phone? Thanks

Anyone?
I also found no solution. I think it's possible without root but no one is updating the Phone Information Apps. We need to get access at phone information 2 and not only on 1

Mine are both 4G / LTE. Inever need to switch the Sims around. Whichever I choose for days gets LTE. this is different from what I had in the Note 8. I was pleasantly surprised. Therefore it may be a settings issue for you. I have the Note 960F/D

you may try quickshortcutmaker app on exynis version and follow instructions in video
https://youtu.be/AdGAB4qRvYA

I feel like the Tasker App could handle this easily.

I dont understand the actual need.
Simply changing preferred network mode from LTE to 3G shall do to stop LTE on any sim.
I use LTE on both sims for calls
I use LTE for data on specific sim by making it as preferred sim for data.
Settings -- Networks -- Sim card manager shall help in these settings.
I am on exynos N960F Indian firmware.

You don't understand the actual need ??
So i will tell you
On my work i am located in a big Hall underground. The Provider i need down there is only coming in with -110 dB and less which is one LTE Bar. If i leave Automatic Mode it switches always in 2g Mode because of much higher Signal. So to get a nice experience and have LTE always available there is no other solution. The same kind of problem is on my other LTE Sim when on different Locations during the Day ! So i have no time to always switch sim cards so that sim2 is forcing lte !
And off course no one else knows this and so i benefit of this extremely fast connection where all others are crying because of no 4g connection

OK understood.
Did not you get one UI already which has option of LTE only selection too for network mode.

Negative. Here the German Rom (dbt csc unbranded)
Has never got LTE Only mode in the menu. This is also for all European Roms. I have had this only when using Root and Custom Roms.
Because i use many banking and streaming apps it's not possible to root this time. Even with Magisk Hide they will not work.
If i could i would have rooted long time ago. This is getting me Crazy really

Many apps available on play store to force 4g LTE.

Sorry but are you reading my Post?
I am talking LTE Only on Sim Slot 2 of any Samsung Phone out today. All the LTE Only Apps or the Phone Info Menu where they lead you is only working on Sim Slot 1.
I am sure there is a dial code like the one it gets you to the Phone1 Information Screen where you can change the bands. But only for Sim 2 (Phone info 2) on Samsung.
So again LTE Only on sim Slot 2 on Samsung Duos Versions is not Possible @ the moment without Root!
If there is any Dev out there you would be the first One to create an app where Phone INFO 2 is possible to change! Or just find the right hidden code for that i know it's there like the Phone Information 1

Hi,
There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

Hey thanks for that. I really was in hope this could work but that would have bean to easy. Unfortunately it's not changing bands after deselecting undefined and than choose some network mode it remains to the same band but it looses the mobile data symbol (but still remains in same band).

This code and all Codes are not working on European Samsung Devices with Android 9 .
I Even Rooted my Galaxy Note 9 and all the hidden codes are Not working ! Even Samsung Phone Info App or other Apps are not working with Latest Android 9.
Only way is Root and Custom Rom like Alex Dev Rom where the CSC is Modified. There it was possible to change both Sim to LTE Only ! But as told before with Root
i loose to many services which are detected even with Magisk . So my next Phone will not be Samsung anymore because of that.

In Settings / Wireless & Networks / Dual SIM, see that only one SIM (you can choose which) can be 3G/4G
Hence one SIM will be on 3G or 4G, second SIM must be on 2G - but if your operator for that second SIM does not provide 2G you will not be able to use that SIM
In Settings / Wireless & Networks you can disable 4G and in Preferred Network type you can force GSM (2G) only - that way you can test which of the two SIM cards / operators provide/have 2G signal

In Dual SIM Settings you choose one which is 4G, the other will be 2G/3G
Cannot help you more, I have both SIMs 2G/3G/4G, hence no matter how I set, both work
Try playing yourself, test both SIMs one by one only, in one and the other slot, with various settings (4G enabled/disabled, Pref net 4G, 3G, 2G only)
Maybe you have problem with one of the SIM cards or one slot
