The Dual SIM functionality in my 7X seems worse than my 5X. With my old Honor, you could leave the SIMs in their slots and just change which one was 3G/4G and the other 2G in the phone settings
However, the 7X seems to have fixed one of the slots to be 2G permanently. You cannot change it in the settings. So I have to physically open up the tray and swap the SIMs, which can be a pain.
Can anyone confirm whether one of the SIM slots is physically 2G only? Or can this be fixed with a software tweak or update?
iirc one of the sims slots is set to 2g only and the other one is 3g/4g

Hi, I am an owner of this very nice smartphone, I'm very happy with it but there are a couple of problems that I'm not able to fix:
- it is sold as a 4G (LTE) phone for the sim card on the main slot and 3G on the second slot, it works only on 3G network for the main slot and 2G for the secon one
- an annoying metallic voice or strange noise when I receive or make a call from/to some numbers with a specific sim card (it's random but always the same numbers, I mean... not all numbers of a specific carrier but only some numbers of that carrier and never, till now, with other carriers).
It occours when that sim card is in the second slot (2G) or in the main slot and I force the 2G network on the main slot.
Did you experience the same problem?

Which ever version of the phone that you get is not able to do 4G or LTE so thats a scam of the carrier and for the noise im not sure what can it be.

Vendor assured me that the phone can go in LTE... I must investigate which frequency use Vodafone in Italy.

And if you can search the web you can see for your self that P6 does not support lte in any way.

P6S does!

Thats what I'm trying to explain all the time.

You are probably right and it isn't an LTE device... but for sure the specs on gsmarena are wrong when they say it is a dual sim dual standby.
It is dual active, I can receive calls on the second sim while I'm engaged on the first, hold this and answer on the second and vice versa.
On huawei.ru they say it is 3G, no P6S found on huawei.com.cn
Yes, you are right about dual sim specs. It is definitely dual active.
On GSM Arena are practically all phones dual sim standby. But this is wrong. However, we must admit the fact, that dual sim active phones are very rare.
I can't find a solid answer on this. I'm looking for a dual SIM phone that doesn't limit the 2nd SIM to 2G, like most older dual SIM phones. I found one source online that says it does support 3G on SIM2 after a software upgrade.
In particular I'm curious if it's supported on LineageOS ROM. My question in the relevant thread for that has gone unanswered. For now I'd be happy to know that it works even with stock.
You can run either the first or the second SIM on 3G, but you can't run both at once on 3G. As soon as you set one SIM to 3G, the other drops back to 2G. This defeats the purpose of Dual Sim in countries like Australia that have stopped using 2G. There's only one 3G radio in the phone.
This information is for the A7 2017, but presumably it's the same for the A5 2017.
A520F-DS, the dual 3G/2G works. At least dual standby. Stock TW. Also works with 4G on 1 SIM.

Some apps might not update the signal strength(Android 1 telephony API, single SIM, 2G doesn't really support the newer(cellids only, no signal strength unless it's matched with the neighbouring cell info), 3G dual, and most of 4G is OK). To fix this, insert 2 sims, set 1 as default for everything, remove that SIM, the signal strength will update for the other SIM.
Band Selection(3G/2G only unless the other SIM is set to that) and Band Disable(4G/3G) works and only applies on the selected SIM. Requires root or specific CSCs.
Cell Locking applies only on SIM 1 and could affect SIM 2.
I've owned three different dual SIM phones (current one is the A3) and none of them could do more than 2G for the "other" SIM. Totally agree with @ryebuck that it defeats the purpose of dual SIM devices in some countries, the more so when more countries will drop 2G in the future. Either manufacturers start making REAL dual phones, or the dual concept will die of its own death.
As with new software updates Mi A1 (sd625) and Redmi 5(sd450) are getting dual volte feature, so why can't we?
Even with qualcom snapdragon website our sd820 supports dual 4g at the same time, so why can't we even get one sim for volte(calling) and other sim for 4G(data only).
As in HTC phones if we change data sim, it doesn't change network preferences, like we can use data on 2g sim, and other sim remains on 3g network. Can't we use this kind of thing? Where1 sim will be on 4g volte network, and on other sim we use data on 4g/3g network.

My z2 plus have LTE on both sims but volte on first sim only. Do you mean volte on both sims?

Yes we have Lte on both sims but not ate same time, one time only one sim remains on 4g network and other goes on 3g/2g. But as per Qualcomm snapdragon our sd820 supports dual sim 4g at the same time. Volte on both sim is a different thing, but still want answers for that also.
yeah ! bro same problem here!!!!!!!!!!!!!!!!!!
Any dev wants to invest some time in it ??
Any possibility of getting dual 4g ?
Maybe sd820 supports dual lte but i think that it maybe more of device specific.... I think our device hardware doesn't support it even if chipset is compatible
Its a modem feature and our device's modem doesn't support it so I don't see that coming.
Has anyone attempted making their single SIM GP6 or GP6P Dual SIM just by changing the tray?
J/Wing before I order tray and find out....
V....1
The 6 Pro (and I believe the 6) are dual sim, its just one sim is an eSim, not a physical sim. Changing the tray will not make any difference as there is not 2 physical sim readers in the phone.

On OS's like LOS and StratiX I believe it reads 2 IMEI and 1 ESID for eSIM.
It should also be kept in mind that Google Pixels do not have "true" dual sim (sim/sim or sim/esim in this case), but "Dual SIM Dual Standby" (DSDS). So even if the in-built sim card/scanner would be replaced, that doesn't solve the software level limitation to DSDS (only one sim can be used for calls, and the other one for sms and vice versa).
I'd like to buy a OnePLus 11 from amazon but does it support dual active sims? I'd like to be able to load balance my data between the 2 sims from different carriers. Is this possible?
Or combine the data throughput from 2 sims from the same provider. Is this possible?

Yes it does. You can use two physical sims or one physical and one esim. I use two physical sims. Verizon and T-Mobile.
As for how dual sims work in Android... You select which sim you want to use data one. You don't use data from both sims at the same time. Though, you can easily pick which one you want the data for.
Both will be able to send and receive calls and texts. Though you pick your primary/default sim for what calls and texts default to.
Thank you!, Now if I can just figure out rooting so I can get call recording going.
That's not dual active. That is dual standby. You won't find any phone with dual active sim in US.
Did you need to buy a dual Sim tray?
Thanks
Oneplus has 3 sim slots: dual nano sim tray and one esim.
Tried to dual esim and sim together but some reason on sim can do nothing but text can't use it for calls since I want esim for data
Well if u use esim and sim, sim can't be Verizon
