[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

Dual sim, dual 3G standby concurrently?

The Chinese variant supports Full Netcom 3.0 which during standby mode allows the 1st sim to be in 4G/3G and the 2nd sim to be in 3G-voice at the same time.

This means in countries like Japan and South Korea which do not have 2G network, both sims will be able to receive incoming calls via 3G during standby mode as neither sims are forced to 2G. As far as I know, this is different from all previous dual sim phones which only allow one sim to be in 4G/3G while forcing the other sim to be in 2G, thus rendering the second sim useless when there is no 2G network available.
From the youtube video reviews of the Indian variant, I have only seen one sim in 4G/3G while the other sim will be in 2G.
Does anyone know if the Indian variant supports dual standby with 4G/3G on the 1st sim and 3G-voice on the 2nd sim, at the same time, like the Chinese variant? Or will the 2nd sim be forced to 2G once the 1st sim is in 4G/3G, and vice versa?

Finally something that I've been looking for since I moved to Japan 2 years ago.
Now if only it doesn't look hideous...

as a force to establish that 1 to 3g sim was, and 2 sim only 2g?

I cannot help you with the question(s) on the Indian Mi 5 variant, but I may confirm that all current generation of phones are 4G+2G only.
http://forum.xda-developers.com/android/help/dual-sim-simultaneous-4g-3g-capable-t3370632

I don't think that MI5 works both SIMs 3G or LTE. Whenever I switch SIM1 as 3G or LTE Preferred instantly SIM2 will go to 2G only.
This is confirmed!

As far as I am aware, that is true for the Indian variant. The Chinese variant, however, is confirmed to be able to connect to both LTE + 3G simultaneously; I have 2 Chinese Mi 5 Pros and they both work as stated.

I have tested on mi Mi5 and i confirm that. First SIM is 2G/3G/4G with data and second SIM 2G/3G simultaneously.
I am in France and it is tested on Orange / Bouygues. It is the fist phone i have tested with this function...

THERE IS NO SUCH THING AS MI5 china variant and MI5 India variant. You would like to think you are special, but you aren't. MI5 is produced in 3 variants (normal, prime, pro) and it's sold in china or in global markets .. like India.
so.. you might have to redo the question, so it can be properly answered. Nobody knows what is India variant of MI5... it might be a clone made in India as far as I know.

Calm down - don't recall saying I was special?
I read that in either the official Xiaomi forums or xda when I was wondering the same thing and some users said they couldn't get dual 3g purchased from the official Indian Mi5 store.
Was only trying to help but ofc you keyboard warriors just can't help yourselves

my mi 5 (indian version) during standby mode allows the 1st sim to be in 4G/3G and the 2nd sim to be in 3G..
however, this ability is kind of an issue for me, because i want my 2nd sim to be in 2G (to save battery & better reception of cellular network)
is there any way to force the 2nd sim to 2G?

In dialer *#*#4636*#*# or tap % times on memory capasity in settings. In additional settings you can chose Simcard 2 and inside chose Only GSM
After restart it has to be set up again.

So.. did anyone get to conclusion here?

Metro SIM in BLU R1 HD not being seen

I have a friend who is on MetroPCS here in the States and he can't seem to get his SIM card to be seen by this device. It was originally meant as a going-to-college gift but has turned into more of a headache than a gift. Yes, we know that MetroPCS uses T-Mobile's towers and the Blu R1 HD is entirely compatible with it...we just don't know why his SIM won't work. Originally we had to get a SIM adapter for the Nano SIM to make it fit the MicroSIM slots, but regardless of which slot we put it in, the phone is stuck on "Emergency Calls Only".
If anyone could help, that'd be a lifesaver, as he starts school on the 22nd of August.
Things we've tried:
Going through the searching for operators function in settings->more->cellular networks
Entering different values in APNs (settings->more->cell networks->APNs)
Restarting a bagillion times
Changing preferred networks
Repeatedly tapping on which sim slot to use for data and messaging
Going into Data Usage only to not find the Cellular data option next to MetroPCS

Did you try another SIM? It's possible that the phone itself is shot. Otherwise, the SIM could be shot. Did you try the SIM in another device? It seems unlikely (however, not impossible) that the SIM and the phone just don't like each other. It's also possible that your adapter is positioning the SIM incorrectly. You should be able to get a good one by going to a T-Mobile store. They usually have a few laying around.

Doesn't Metro require you to give them the phone's IMEI before being able to use the new phone? Contact Metro CS and tell them you got a new phone that you want to use and give them the IMEI
If you alrdy did that then try using another active SIM (borrow from friend/family) and see if that works fine with the phone in case the phone is defective

I have Metro PCS and this phone. You need to call MetroPCS and give them the IMEI. Make sure you give them the right IMEI as there are 2 SIM slots on the phone - each with its own IMEI

We went to a T-mobile store to get a good adapter for free.

Thanks, we'll try this!

It worked. His phone is now setup thanks.

I think you should try other options listed in the Set Preferred Network Type, based on the type of Network listed the Wikipedia article. You can try to research about what type of network your carrier uses, then mix and match it until you get the appropriate setting.
Anyway, thank you for the *#*#4636#*#* that let me fixed my network.
Have a nice day fixing!

So finally i found the solution.
I found out that i had problem with dual sim. When i was using dual sim i was getting EDGE (2G) on my primary sim but when i removed my secondary sim then 3G/LTE start working . Even swapping primary and secondary sim in sim slot one and slot 2 was not helping. It is quite strange but it solved my problem.

Thank you so much! The mobile data was lacking in my Moto G6 Plus (running the official release lineage-17.1-20200407-nightly-evert-signed.zip). Once I tried to remove the SIM 2 from my phone, the mobile data worked so well. Then I pulled the two SIMs into my phone, and happily both worked at all. :good:

You're the best brother. Thanks for the solution.

I have bn using android 11 on SM-A705FN. Then I can switch to any of two Sims for internet. Just from drop down, there are options sim1, sim2 and data Sims to choose any sim for it, depending the sim that was subscribed for internet.
But now on lineage os 20....no such privilege. The phone automatically chooses Sims....
Please help rescript this error so that person can choose any sim for internet....thank u...

Wifi calling and Volte

Hi. So I was having trouble with calls, signal drops, very annoying whooshing noises and so on. When I contacted the carrier they said let's turn VOLTE THEN WIFI CALLING. my wife and I have the p20 pro CLT-LO4 and neither of our phones have an option for volte or wifi calling. Contacted carrier(Koodo) I'm in canada. They said well it's suppose to be there reset you phone and check again. No dice then press *#*#4935#*#* and it does nothing. They say it's enabled on there end and don't have a solution... I called Huawei and they took my serial number and model and told me that it's the carrier 100%....

try this.
Open phone settings > Wireless & networks > Mobile network > both VoLTE calls and Wi-Fi calling settings should be there.
if you can't find, it is because the carrier disabled it in the rom. Try to unlock bootloader, root and flash an international rom to get it back.

When I talked to the carrier they assured that it was unlocked.
If you have a link on how to preform the tasks you said ide definately give it a try
Thank you

One question tho is it possible to brick the phone? Reason I'm asking is my wife's phone is 8 months old but I just switched from my s9 to this one 2 days ago so i can tech bring it back and get a refund but the problem is there isn't any other phones offered besides the p30 pro that compare and I would have to pay $690 down plus 20 a month for 24 months where as p20pro was $0 down and 15 a month.

If the carrier supports it, then you should have the option in settings. In my case, when I bought the phone only one of the two carriers that I have in each sim card was supporting WiFi calling. Now that both support it, I have it in the settings. The problem that I have found with WiFi calling though is that if you start a phone call through WiFi and you move to a place with bad reception, then the call is dropping. Also, if you are on a WiFi call and you go to a place where the wifi has no reception whatsoever, then again the call drops, instead of switching to normal call. In other words, whatever the way you make the call, you have to finish it. There is no switching during the call; this became really frustrating, so I now switched it to mobile network preferred

Alot of misinformation about this on the net.
Regardless of what your carrier says this is in fact a carrier issue.
If you simply swap sim cards to another carrier that DOES support these features on all phones with no restrictions then it will show up in the settings.

This screenshot is from a Mate 20 X but the same thing shows up when I insert this sim into a P20 Pro.
(Oh....in the United States when you pop in a T-Mobile SIM you will have Volte toggle in settings but not on ATT)

T-Mobile SIM 1 , no volte toggle here thanks for the clarification. My post was primarily to reinstate your point about WiFi being carrier/SIM dependent.

hi i tried searching in google for the volte enable in my mobile device Huawei P20 Pro , my other sim says it is volte ready however the other sim volte radio button cant be seen i tried switching sims but everytime i switch sim the volte button will transfer leaving me a sim card tray with no volte does this mean that it is the carrier needs to enable volte? others say that i need to wait for update on my mobile device

My device has a model CLT-L29 Global version for Huawei P20 Pro EMUI version is 10.0.0 Android 10 and it says for this version there is no update for EMUI 11 so does this mean i can not use volte anymore or do i need to contact carrier for the volte to be enabled?
