[SOLVED] Dual SIM: 4G/3G? - OnePlus 3T Questions & Answers

Does the OnePlus 3T support both SIMs on anything above 2G? I have one SIM (lets call it SIM X) that needs to use 4G/LTE (data only plan), the second SIM (lets call it SIM Y) is used for text/talk and needs to use 3G because the service providers doesn't have a 2G signal. Can the 3T (Canadian version) support this setup?
I've tried asking OnePlus this question, i get a different reply everytime. Hoping someone from the community could give me a definite answer.
Thanks
SOLVED: So I bought the 3T. The scenario outlined above works. And it is dual sim standby.

No problem setting it up like you described in cm13 and I think oxygen will work also. I did data on my sim 1 and calls and texts on sim 2 setting it at wcdma only and it works fine on 3g only.

Samsung Galaxy S5 Mini Duos Opinions?

Hey there,
Does anyone has this model??
What the opinion about it??
Hi,
I have similar question.
Does anybody have this model?
Are there any issues like there were with S4 mini duos? Mainly network issue it was experiencing, dropping connection and never reconnecting until reboot, poor signal sometimes, etc.
Is the dual sim active-active like on S5 duos? In case you are in call on SIM1 and someone tries to call SIM2, do you get notification or it is sent straight to voice mail.
I'm really tempted by this model, to replace my old HTC HD2
Thanks for any input!

I have this one, currently the main problem for me is poor battery life, I have 3g/4g enable whole day to receive emails and at the end of the day te baterry is at about 50-40% . I did not noticed any issue with network. Regarding the dual sim I'm not sure, if I call from one sim to second sim it says that the number is not responding.
Cool, thanks for info. Friend has S5 and he isn't able to get even 1 day out of battery, so I'm prepared to get 2 days max out of it
Regarding the calls, I have found out that if you are on call on one sim, other one is disconnected, but what you can do is apply call forwarding on each of them (of course you need to pay for that) and then it will get redirected to active sim.
@squider: Im curious, can you tell if its possible to set 3g either on SIM1 or SIM3 (seccond one will have to be 2G).
What I mean if I have two SIM cards (3g on SIM1 and 2g on SIM2) and I'll finish network packet on first, do I have to phisically swap SIM cards, or only change settings, and set 3g to SIM2, and 2g to SIM1 ?

Yes, you can set in settings which sim should use 2G and which 3G..

[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

920CD Dual sim - is it active?

Could you explain how dual sim works?
Does it work at the same time or have to switch between sim1 or sim 2?
For example
Use SIM1 one for internet browsing – somebody will call me on SIM1 or SIM2. Will phone ringing on both? Or for SIM2 calls have to switch to SIM2?
interested to know as well.

You have to turn call forwarding active.
Under sim card manager, lase section general you need to select dual sim always on. with this if you are speaking on sim one and you get a call on sim two it will come on sim one as it will get forwarded. so you wont miss calls from either sim even if you care on a call.
For internet both card slots have 4g but only one is active 4g and second will be 2g. you can select whichever you want.
I have N9208 and assume it is the same for dula sim Note phones.

So there is no way to get calls to both SIMs without calls forwarding?

Not 100% sure but don't think so mate.
You'll get calls to both sims when idle, unless you're already talking on one. That's when you need call forwarding, so you won't miss second call.

What about situation when use internet data? For example downloading file using SIM1? Can I still get calls to SIM2?

Yes. While downloading if you're setup to use data on sim 1, you'll get call on sim 2. When you pick up that call download will stop I think. Not 100 percent sure cause different phones have different arrangements... If your call comes on sim 1 the data will continue to download. Vice versa.

Hi. I have a galaxy note 5 dual sim (n9208) and when I'm on a call on sim 1 (configured as 2G), automatically i lose the internet connection in the sim 2 (configured as 3g/LTE, but my network is just 3G) and I stay without internet connection all the time while I'm on the call.
I have set the sim 1 only for calls (2g) and the sim 2 only for the internet (3 / LTE but my network is only 3g).
It is very inconvenient not to have internet connection while you are talking on the phone you can not receive a whatsapp or browse.
There is a way to solve this problem?
Thank you.

Second sim is not available, when you are using the first one (when answering/making a call).
...and if I am surfing on socials like Facebook in SIM #1 does it work receiving call on SIM #2 or is it stopped?
EDIT: solved
Similar to the Huawei Mate 10 series, the P20 and P20 Pro can support dual-SIMs with dual 4G and dual VoLTE running at the same time. This provides the best dual-SIM experience as both lines are connected to the best network possible. It also supports download speeds of up to 1.2Gbps with 4X4 MIMO over a 4.5G LTE network.

This all depends on whether you have the dual sim version of the P20 Pro. Most UK versions are single SIM only. Allegedly, these can be converted to dual sim using a guide available on this forum or using the funky huawei paid service. I am still looking for full verification that this workaround is fully functional or not. Goes without saying that, you will also need to buy a dual sim tray for these UK versions of the P20 Pro.

Oh, I'm in Sweden, and my dual SIM works like a charm. Have my work sim and private sim running simultaneously without any issues at all. I opted in the settings to run the surf on sim 2 since I have more data on that one even.
I do wish I could set one number at "do not disturb" at a time. Or change the ringer to vibrate or silent for just one of the phone number.

@OP
What this guy said is 100%
The only way to obtain dual SIM from a single SIM variant is to essentially lose bootloader unlocking ability by using the funky Huawei method.
It's up to you to decide which you think is more important.

What's the difference between active and standby? Plus, did you rebrand your phone after network unlocking it? Did it affect the network unlock at all?

Uhm, well. Mostly here in Sweden the phones are unlocked and unbranded. So, I just smacked my work sim and private sim in the phone and activated the "dual active 4G" option.

You dont. Try to make a call from sim2 when sim1 is engaged in a call. Or be on a call on sim1 and and get a notice when someone calls you on sim2 and change to that call. You cant do that and that is the difference of dualsim standby and active. The last Huawei device to have dualsim active was the Honor 8. After that they have stopped supporting it, cheaper with standby than active

Yeah that works. If I'm in a call I can add a call using the second line without the first call dropping out. The first call can't hear me tho, unless I switch back. But, both are connected, just the the speaker and mic can only be connected to one at a time. I figure that's a software limitation tho.

Strange that your phone can make it but not mine. And since the phone just supports dualsim standby and not active it should not work. Thats why there are an option to forward calls to the other sim when the the first one is engaged in a call as it is not possible to have both sims active at the same time as the phone just got one radio part.

I actually just tried after the last comment to make sure. And it works. It might be because both of the cards are on the network provider "3" and they do the calls over 3g and 4g since they don't have 2g access. And as my earlier screenshot shows, you can have both of the 4g's active at the same time.
But if you're right about that "one radio part" shouldn't that also be impossible? I'd think it's weird to build in two 3/4g antennas and just one 2g.
Sorry I have to revive this dead topic.
Is there an updated list of DSFA smartphones (dual sim active, two radio modules)?
I know DSFA can somehow be "emulated" using VoLTE /dual VoLTE or VoWifi if the device and carrier supports it.

Volte issue in Oneplus 3T
