Dual-Sim SmartPhones - Can it be done on Android?

Hi all,
I currently own a Blackstone and its been pretty good to me over the past year or so. However I have two numbers and I have to carry two phones around with me. I have been looking into dual sim for a couple of days now and all i can seem to find is either dodgy Chinese copies or really old Samsungs.
In the USA a company called General Mobile have made an android phone with dual sim the kernel for it is below:

Do you think there are guys out there who would be able to get this to work on a HTC Hero, for instance, with a dual sim adaptor? Or does the phone have to have two antennae?
Are any of you guys aware of any dual sim smartphones coming out?
Thanks for your help, Serg

Android and dual SIM

Dual SIM Android phones seem to be an excellent mechanism by which device vendors can suppress the urge of us nerds to install alternative ROMs on our phones.
If I use a single SIM phone I have a choice between a decent cheap Internet connection, and expensive calls to friends and familiy, or a crap Internet connection and cheap telephony.
So if I (could) install CyanogenMod, I would effectively have a single SIM phone and have to settle for one choice or the other - right?
Dual SIM phones are popular in China, India, Africa, and probably South America - half the world's population or more. If Android had full support for multiple SIMs perhaps device manufacturers would think twice before going it alone purely on the grounds of cost, not to mention subversion of the common OS.
Nice weather today!

I would suggest waiting for something like the S4 Duos to come out. It already appeared in Sammobile. After it is released, Cyanogenmod might add native support for dual sim phones to their source code, making it easier for other dual sim phones to support dual sim on their respective Cyanogenmod builds.

I used Cyanogenmod as an example. I think it is Android that needs to recognize people's justifyable need to use dual SIM phones, and make it core!

tnx bro
what about roms? which one is better? motorola or google play version?
generally nexsus are more better.cuse better support .but i dont know motorola
which one have better support for updates and what difference did you seen in motorola rom and google ?

Currently most ROMs only support single SIM variants with very limited support to dual sim devices or none at all, but this can change later.

The moto g runs stock android. Its not a custom skinned rom like HTC and Samsung like to do. So really, the only difference is the GPE doesn't have the 3 Motorola apps (migrate, help, and the better moto camera app). Also, the GPE will get updates a couple months before.
My suggestion is get the normal moto g because of the camera app is better. Though, really in day to day use, you'll never notice if its the normal one or the play edition.

3 actually usefull apps and also Regular Moto G has an F2fs file system which was first used in moto x and promises faster random data reads ( faster read performances )
And about the updates....You can be sure that as soon as Moto G gpe would get any s/w update...it will be ported soon enough to regular one too

>Dual vs Single: Dual SIM
Why?
Because you will have space for one extra SIM if some day you need it, no harm in having two slots while if you have only one you might need to buy a new phone just for an extra SIM.
>Google Play vs Moto Version: Google Play
Why?
You will get unlocked Boot loader with warranty which you loose out in Moto Version in case you unlock your Boot loader.
Its like they unlock the boot loader for you with the warranty intact.
This will allow you to play with different ROMs without loosing out your warranty.:laugh:
For software support, Google ROM support will always be better than Motorola any day.
Further, in case of Hardware issues you shall be contacting Motorola in both cases so you aren't loosing out nothing
by buying a Google play edition.
Verdict: Dual SIM Google Play Edition :good:
Edit: as mentioned by @jaspreet997
Such phone is not available and also I have checked up the same.
So then opt for Simple SIM GPE untill and unless a dual SIM is very very important to you.

Are there any dual sim gpe being sold anywhere? I think not

tanx again
generally single sims have better development(i dont know about motorola).if its true on motorola.its more important than one sim more
in my country motorola havent eny office and the waranty isnt meaning here!
i think moto version will get updates as soon as the GPE got
so the motorola one sim looks better
thank you all

Reading this I again realized how different we people are. Because I would vote for a single sim regular phone instead.
- Why single sim? Because of the fact there are much more roms supporting only the single sim variant. Of course there will be dual sim roms, but when? I dont know? If in a month, then thats good. If in six months, thats bad ... many of us dont usually keep devices like this more than a year and being without flashing half of the time - nope, thanks!
- Why regular? I like what (little) Ive heard abou F2FS. And I dont care about warranty - I already have no warranty for my phone because I screwed up the purchase ... but thats another story
So, my advice - unless you need dual sim (or are going to need it soon), get regular single-sim.
Or not, it doesnt really matter lol ...

Good points.
Regarding f2fs, how hard can it be to format a partition? I'm actually wondering the answer to this, as I have the GPE and it seems CM11 for the Moto G just went official. But like you said, it looks like the GPE and the dual-sim owners will have to wait longer.

[Q] TMobile Z3 vs Sony Z3

Hey guys,
I am looking into getting the Sony Xperia Z3. I just have one quick question.
A while back I purchased the Xperia Z (C6602) from sony directly and I used it on tmobiles network. After purchasing the phone I found out that tmobile sold the (C6603). These phones are similar, however they do have different specs.
My main question is, is there any difference between the Xperia Z3 that tmobile is selling compared to the Xperia Z3 that is sold directly by sony? (other than the available colors)
Thank you for your help!!!

Two things primarily: The T-Mobile model has 32 GB of RAM vs. 16 GB and its bootloader is locked.

Also the T-Mobile one has LTE Band 12 which no other model has.

You mean 32gb storage, it has 3gb of ram

Tmobile version has band 12 and wifi calling.

And the T-Mobile is only in black and carrier branding...no thanks!

Reason I would reccomend, TMO version is the 14 day replacement/exchange period. I went through 3 and on 4th and possibly final one. If you buy from Sony directly you will be stuck without a device for weeks if you send it in due to defects only to probably get a refurbished one.
The TMO emblem is pretty conspicuous unlike Verizon so that should not be an issue.

I think you mean to say "inconspicuous" . Anyways I agree, looking at it, it's also a much lighter shade of gray/white than the Xperia or Sony logo, so it actually blends in quite well. There's also no T-Mobile branding on the front, which is really nice.

Hardware differences:
32GB Storage
T-Mobile Branding on back
Band 12
Software:
Bloat: http://imgur.com/oXLCzjj
Bloat not removed: wifi hotspot needs hotspot on plan, Device Unlock
Bloat that needs PM BLOCK: CarrierIQ
No bootloader unlock

I believe only the T-Mobile version has wifi calling.

You can opt out of Carrier IQ, the bloat is not so bad actually fewer than most carriers and they can all be disabled. For the extra 16GB its worth it. Only thing for you to care about is the boot-loader unlock. WiFi calling is also a plus.

Hello, it's pretty simple in this case.
512 GB version is available internationally, is single-SIM, has fully working VoLTE and VoWi-Fi, has firmware named PCH and its global ROM is vastly superior to the Chinese one (less bloatware, very little restrictions about customization).
256 GB version is available only in China, is dual-SIM, has neither VoLTE nor VoWi-Fi, has firmware named PDEM and its Chinese ROM has some bloatware and more importantly unpleasant and incovenient restrictions for the user.
Hope that helps
More advanced answer:
Currently there's a battle on two fronts:
users try to flash the much more user-friendly Global ROM on the Chinese device but without success so far; it seems that an unlocked booloader might be required which is still a long way to go
users try to make the Global model work as dual-SIM as it actually physically has a double SIM-card tray so there is a tiny possibility that it's a very weird software limitation (breakable in the future) but I would't have high hopes

Thank you, I want / need dual sim, (work etc) so will probably have to give this a "miss" unless.......

No problem, glad I could.. "help".
No one has a clue why Oppo made this limitation, both phones (CPH and PDEM) are identical (hardware-wise), both have dual SIM-card tray but only the Chinese software is capable with working with two SIMs.
The phone is so great I might let go of dual-SIM requirement but I understand it's the decisive factor for many. Oppo has surely cut their profits by doing this and I've never seen anything like this before (phone hardware supporting it but an artificial software change blocking it).

I agree totally, it's ludicrous that this should be the case?
If only they gave users the choice? After all it's £1099 phone, it should be!?

Apparently Clove, (UK) has the dual sim version. Ceramic black only though, at the moment.

It's either a typo (misleading information), or they're offering the Chinese model with Chinese software and 256 GB storage (the latter option is very unlikely).
Remember, technically the phone is always dual-SIM. That might be the source of their information.

I have emailed them for clarification, awaiting reply!

Got the reply!
Hope this helps ?

Ok, that sounds strange (or interesting, depending on the point of view). Currently, as the international CPH version of Find X2 Pro doesn't support dual-SIM, there are two possibilities:
- they're still sharing misleading information (deliberately or not) and the phone will be single-SIM
- the phone will come with a brand new version of Global ROM firmware which somehow enables dual-SIM (and which hasn't been released yet), which would give hope to other users of international CPH version.
Hardware-wise the version you're ordering is 99% the same as the ones already released in countries like Netherlands, Germany.

Yes this is very odd...not sure what game they are playing. Why would the UK get dual SIM, or some specific market. This is driving me nuts.
Maybe I'll contact oppo directly.

I might add, that until this question is clarified? I will not be ordering,
Single SIM?
Dual SIM??
it's just all over the place at the moment??

I thought i posted this here also :
Ok after some research, and reading another post in the forum, i can mostly confirm that there ARE 2025 GLOBAL models with dual sim around. Apparently the Clove is getting the dual sim.
Clove find x2 pro
and i confirm this is correct by going to the UK site of oppo...
Oppo official site
This means that's even crazier than i thought... some markets, even in the EU get the dual sim and others dont....
but just to make you laugh check this out :
Oppo says ALL their phone are dual SIM

I stand corrected!!! Oppo is really not clear on this.
As this is very WRONG
on the top of their site : it says "dual 5G" which can make one believe that it's dual SIM. But when you scroll down to "network" it clearly says "Single sim".
Uk Oppo site
So why do they mention dual 5G ?(maybe the two 5G (mmWave and the other one).
I sent an email to Oppo asking for some clarfication.
I checked all around the world which markets have dual sim (outside of China) and apparently none have it.
So i'm waiting on feedback from another member who has a 2025 but dual SIM... this is all very confusing.

just to add some more confusion (salt into wounds, so to speak) into this... Amazon UK also claims "dual-sim" in their pre-order for June 10th release. Also Orange version, 12GB 512GB.... sold and dispatched by Amazon... :crying: :fingers-crossed:
I loved this phone in PDEM version but the lockdown of the software made me switch to Xiaomi Mi 10 Pro (plus I can use custom roms). Dual SIM especially since this is band capable for TMobile and Verizon in the states. I love dual sim... if dual sim is confirmed, i'm switching back in a heartbeat... just given the facts though, I think it is sellers typo in their information. Oppo clear states on UK site, CPH2025 model, Single SIM.
