[Q] Dual sim with Lte support

Hello everyone,
Anyone knows if there is any info about some phone that is going to be released in the near future with dual sim and LTE support?
Thanks.

Tell me about it.. I have been waiting for years!!
the problem with dual SIM and LTE is that the processing power required to decode the LTE signals is far grater than what we have today.
dont despair though! I just read that Mediatek is releasing a powerful 8core chip that can handle the processing load and that is Great news! I expect we will have something soon (Q3 2014)

Both the new Sony Xperia M2 and Xperia T2 Ultra support Dual Sim and LTE. :good:

ummmm.. definitely not!!
The phones you are talking about are single SIM.

The only dual SIM UE is the E1 DUAL and it's not LTE:

Trust me, there are no phones out in the market yet.
There's just no juice for LTE AND 3G dual SIM yet. I'm a telco engineer, it's my job!

I'm actually referring to their "dual" variant, the Xperia M2 Dual and Xperia T2 Ultra Dual. My mistake for missing that.
The reason I said they both support Dual SIM and LTE is based on the following announcements:-
http://blogs.sonymobile.com/press_release/xperia-m2-best-smartphone-tech-in-its-class/
http://developer.sonymobile.com/201...a-6smartphone-for-large-screen-entertainment/
Sony is not very clear with their announcements on whether the "dual" variant includes LTE or not but I did saw a few articles mentioning it:-
http://www.tomshardware.com/news/sony-xperia-m2-dual-sim-4g-lte,26101.html
http://www.mobileburn.com/22423/new...debuts-with-6-inch-display-lte-and-dual-sims-

Actually the Xperia T2 Ultra Dual is not LTE:
http://www.gsmarena.com/sony_xperia_t2_ultra_dual-5968.php
and the specsheet:
http://www.sonymobile.com/global-en/products/phones/xperia-t2-ultra-dual/specifications/#tabs
...and neither is the M2 Dual. Here's the Spec sheet for M2:
http://www-support-downloads.sonymobile.com/d2302/whitepaper_EN_d2302_xperia_m2_dual.pdf
All the phone manufactures post these vague reports because the people who are creating the reports have no idea about the product specs. The LTE version is the single SIM model of these lines, the Dual Sim version only has WCDMA.
There are three main chip manufactures - Qualcom - Samsung - Mediatek. All smartphone companies carry either one of the three, or a variation of the Modem chip.
Currently, (read the first reply) there is no chip capable of handling LTE demodulation/MIMO. The processing requirements are too Damn High! (meme ref).
Mediatek though, is the first one who has announced that is building a chip that can handle the load. The Octa- Core MTK6592.

My next phone must be dual sim and lte and less then 6" screen. I thought to have it for my brthday in july. Is there any chance? Somebody knows for sure if that THL W11 Monkey King 2 will support lte or i should wait for MTK6595 definately? (it would be fine for me even if one sim is lte and 2nd one is 3g).
Thanks

Guys, this is an important question...How does big little actually work? Does it only uses only 4 cores at a time? I have read around and this seems to be the case, at least for current implementations.
Mtk6595 phones are coming out but if that's the case I'd rather stick with mtk6592 and have better multitasking. I don't care about 4g.
I'd like to know more about the mtk6595 :s
According to this link tough, the mtk6595 might use all eight cores simultaneously.

The principal question is if there are apps using 8 cores at the same time. You could have a powerful device with 8 cores working at the same time, yet if there aren't apps using this permormance...
M1S - Patatalk

As long as different apps use different cores, even just 2 cores per app, it is still a great deal.

I think i've found something http://www.aliexpress.com/item/4G-T...e-2G-RAM-8G-ROM-Android-4-4-5/1840816089.html . But i'm not sure if this information is real or fake because i can't find official page of the vendor
UPDATE: The brand/vendor name seems to be "Vivo"

And here's another one http://www.chinaecarts.com/samsung-...nch-mt6595-android-44-32gb-lte-4g-p-7591.html (see comments, there's a model with 2 sim and lte). Also some unknown/fake brand with no guarantee of future rom updates nor cyanogenmod...

This is a post for Dual SIM devices with LTE. Why the hdll are you posting CPU Q&A???????

Here's another one model http://hiton.en.alibaba.com/productgrouplist-221621342/Octa_Core_Smarphones.html which at least has official crappy website http://hightoncn.com/ .
+1, please post/search for dual sim lte devices and don't offtopic about cpu or any other features differnt to 2sim+lte in this topic
UPDATE: and there's seem to be LTE version of UMi X3 http://www.aliexpress.com/item/2014...-octa-core-smartphone-5-5inch/1764609798.html

Looks like Huawei Ascend P7 has dual sim version with lte http://liaow.com/huawei-ascend-p7-w-black.php
In some reviews they say that the second sim slot can also be used either for sd card or for sim card, so you can choose between additional sim or additional storage. But i don't know if it's true or there's just 2 different versions of that model: one with extra sim slot but without sd card and another is single sim but with sd card.

And the HTC One E8 Dual SIM http://www.htc.com/cn/smartphones/htc-one-e8/#/ use Google translate. Limited LTE bands however. Possible June release in China I think.

I'm afraid the same about the bands of all models that i posted above if not sold specially or officially for the countries with different bands than china's. And sure I'd like at least 3g for the second sim if i want to switch data connection to another sim. You could just interchange sims in that case but for example Huawei has one sim micro and another nano so it's impossible to do so

Yes a good bit of research is necessary!
I think I've only seen the ZOPO ZP980+ to have 3G + 3G - pretty rare to find.

I like the HTC E8... Are there any news about availability around the world? I'm from Portugal

It's only released in China so far, not sure it will be released wider, the M8 dual SIM has just been released an a few European markets. You could always import an E8, try merimobiles etotalk etc etc.

No, because the SoC doesn't support 5G.

Mate 10 will do

I think Mate 9 and Mate 8 will not support 5G network.

mate 9 is almost 2 years old model and 2 years ago chinese operators are not supported 5g standard yet. now some of them are upgraded and newest phones like mate 10 and honor 10 will support 5g.
but I think mate 9 is still great for 4g because it has dual sim dual active option (DSDA). so you can call using first sim and second sim card will be active and data will work so if you need to be always online, this is the great solution.
anyone know mate 10 will be DSDA too or only one sim card will be active ?

Mate 9 is Only 10 months old and Not 2 years, it doesn't support full active 2 Sims as you mentioned, and the last device from huawei was the P9 with DSDA.
FUTURE devicew will not support it as well.

I heard that asus is still producing devices with DSDA function (like zenfone 3 or smth).
huawei was great with mate 8, but this is old device already.

不支持。It won't support,because the Balong 750 only support 2G/3G/4G LTE Category 12/13.

Since the standards for 5G have not even been finalized by the ITU yet there are NO phones yet that support it. Even Qualcomm has yet to put their 5G into any SoC yet (late 2018 supposedly) let alone that there is no network infrastructure yet in place

From what I understand the 600 Mhz is just a uhf channel (which was used for TVs back in the days) and its only advantage is that it could be used in rural areas. 5G is completely a different animal.

OnePlus 7 pro 5G dual SIM, but not active?

Hey all, as from today I'm a OnePlus 7 pro 5G owner... With a bit of a downfall.
Before I bought the phone I made a bit of research about this device to see capabilities and if it's worth the money.
As I know this device is dual SIM from factory and I was expecting my op7pro 5g to be the same... and it is in a way, but has no functionality of dual SIM phone.
When I've pulled the SIM tray out I could see inside the phone on both sides of SIM tray has SIM pins to make contact to the SIM, so I've made one of the SIMs to fit in the tray because is not a dual SIM one, but you can adjust the SIM card to fit there.. and I know it's not the SIM faulty because I've tried it on and works.
Any idea how to make it work dual SIM... I have to specify it's on a contract from EE UK.
Please give me some ideas, I know to all the stuff with ADB so I'm not afraid to use it ?.

If the phone came from EE instead of OnePlus directly, then it might be subsidized (payments) through the carrier. If it is not unlocked (cannot unlock the bootloader), then you probably won't be able to fix it.
Here in the States (USA), TMobiles OP7 Pro is locked and the second sim disabled. But you can fix that by unlocking the phone and flashing the International Rom to unlock the second sim slot (second slot is software locked, not hardware locked), allowing dual SIM if you can get your hands on another sim tray with the dual slots.
Don't know if this is the same for you, but it is worth looking into if your carrier does lock the phones down and allows them to be unlocked.

It's not dual SIM as it's a limitation of the 5g modem

The 7 Pro 5G IS dual SIM capable. It has 2 modems. The Qualcomm X50 5G modem and the modem built into the SOC for 4G. It's the firmware that's restricting dual SIM functionality. If you wish, you can convert to the international variant but you WILL lose 5G connectivity (if you have it).

yes I own the Oneplus 7 Pro and that sim tray is the exact same one that goes into the OP7T Pro Mclaren.
I have t-mobile and i bought my sim card slots from amazon for both the OP 6T and OP 7 Pro. I was able to successfully convert each of those phones using msmtool. But the damn OP7T Pro Mclaren 5G from t-mobile I can't find a solution.
I have the Oneplus 7t Pro Mclaren 5G Edition and all I want is to activate dual sim. At this point I don't even care if 5G works. I would sacrifice it if there was some way to install OP7T Pro onto the OP7T PRo Mclaren.

Can I confirm that you tried using a OP7Pro international firmware via MSMTool on your OP7PRO5G? Did you ever fix the issue?
I'm just trying to workout if using a OP7Pro international firmware makes it work as a dual 4g sim (I really dont care about the 5G)
FyI I have a OP7PRO5G(EU)
I tried to use msmtool to make it a op7pro international (was a fail or I wasn't doing something right....I get "Param pre-processing") Can someone please advise me.

Hello how i Can do'it?

Is the OP7 pro 5g worth it?

Hi everyone,
From my understanding, the 5G version (EE) is more expensive and has 5G, but: a) does not support dual sim, and b) receives updates much slower than both OP7Pro (4G) and OP7 (the 5G version seems to lack the camera improvements in the 4G versiom)
It seems the other 5G versions don't support dual sim as well (because of the 5G modem) but given the poor firmware update support, is it worth it to get the 5G version (esp if it will be your phone for next two years) or to just wait for 7T pro 5G (hopefully with dual sim) or for other phone manufacturers to release 5G phones with dual sim?
Thank you

No.
Not worth the money. Current 5G phones use 4G to establish network connectivity and only upload at 4G speeds.
Waste of money to get a 5G phone before 2021.

yeah waste of time. My mate has a 5g one plus 7 and hes still back on .4

Still too early for 5G...

Coming from a 5G owner, it's definitely not worth it because development is non-existent...

When we will have 5g network, yes. Now, NO !

Download and Upload speed transmited over 5G network, signaling data on 4G when using Huawei equiqment.

Is it true when you enable 5G you lose dual sim functionality?

Nope..you can just have 5g on one sim card available. Second sim can be still used for phone calls etc..

so you say when 5g is enabled, phone is only single sim? I thought one 4G + one 5G. Could you please try if SIM2 can work with 5G? or 5G has to be SIM1?

When 5g is enabled, phone is only single sim and sim1or2 doesn't really matter.

Yes poco said that when you use 5G phone will be single sim till they will give update that will make 1 sim 5G and other will be 4G

You just have to read the user guide.........
About Dual SIM:
• Supports Dual SIM cards with no carrier restrictions, single 5G or dual 4G
connectivity ①
• Supports Dual Nano-SIM card slots, either card can be set as the primary
card
• Supports single SIM 5G/4G+/4G/3G/2G
• Supports Dual SIM 4G+/4G/3G/2G
• Supports Dual SIM VoLTE HD calling ②
Note ①: 5G support depends on the local telecom operator’s network; if
the primary card 5G is enabled, the secondary card will not be available;
subsequent software upgrades will include support for primary 5G and
secondary 4G/3G/2G card mode function in dual-card situations.
Note ②: VoLTE service availability depends on the local telecom operator’s
network and service deployment
Not so complicate....

So according to the user manual dual sim support while 5g enabled is coming with a future update? the phone is five months old, did the promised update come through yet? are all other ROMs available for this device have the same issue?

The promised update is yet to come .

The phone was launched 5 months ago but probably due to the pandemic there is surprisingly little development and discussion from the community's side. Barely 4 roms.
I have been waiting 2 months now to upgrade because there is no way I ever use MIUI.
Last week LineageOS was released, but it's Android 10, and only initial build.
I will probably wait or lineageOS 18 before I buy this phone, but this means waiting few months the way things are going.

Dont forget that very few people use dual sim on their phone... Not a priority to fix ;o)

I would say there are more dual sim users than 5G users, maybe that's it.
