Best DUAL SIM android phone?

Thanks for the replies!


From what I have read the two models mentioned by Crake -
the HTC T528w and the CoolPad 7728
are dual stand-by phones like the Samsung Galaxy S Duos.

I would very much like to know how the ZTE U960, or alternatively the ZTE V970 behave in practice.
Has anyone actually used either of them handling two calls simultaneously?

One other thing I like to know is, that since most of these phones are intended for the Chinese and far eastern markets, do the European branches/dealers of these makers give any kind of support, or even guarantee these models?

No my Friend, you're wrong.

The phones i told you are DSFA, that means, DUAL SIM FULL ACTIVE, no more information is needed !
 
Thank you mikedt!

The more I read about these dual-sim phones, the more I get the picture that the "Chinese" models' buyers from the rest of the world, are more or less on their own, as far as guarantees and servicing goes.

What has puzzled me is the policies of the bigger brands like Samsung, HTC etc. with the dual-sim models.They seem too reluctant to introduce such models in European or N.America markets, and when they do, they do it half-heartedly.
I understand the priorities of promoting their multi-media loaded models and targeting the younger customers, but I don't understand the neglecting of the (quite large I believe) market segment, which still uses these contraptions as..... phones!!!
What would it cost to them -I often wonder- to have just added dual-sim active features to, let's say, the Galaxy S III or, (God forbid!).... the iPhone 5??

I'm sure it's the way the carriers operate as well, seems in North America especially, you're pretty well expected to be buying a phone subsidised by the carriers and taking out a two year contract with them. The phones are probably SIM-locked to the carriers. Would be rather pointless having a SIM-locked dual-SIM phone.

Whereas in Asia phones are usually not subsidised, not SIM-locked and most people seem to use non-commitment pre-paid plans.

The whole idea of dual-SIM phones started in China, because of the provincial roaming they have here. I've got SIM for China Mobile Inner Mongolia, which offers very cheap calls within the province. However I frequently go to Beijing, I get charged much more for calls and have to pay for incoming calls as well. So it pays me to have a China Mobile Beijing SIM as well, for the time I'm there. However I don't wish to carry two phones around with me.

BTW you can also get triple-SIM, and even quad-SIM phones as well.
 
It appears to be quite a thick chunky phone, I would say that it does have a large capacity 2750mAh battery. The battery in my Lenovo is only slightly less than that, at 2500mAh. Don't know who the manufacturer is though. Seems to be distributed by quite a few Shenzhen trading and wholeale companies. Also it more than likely has Chinese software and is Googleless.

Thanks for the reply mikedt.....I wonder if there is there a way to know the exact or approximate capacity of a battery using ??? This would help us is claiming refunds from the seller if we pay with Paypal ...
 
No my Friend, you're wrong.

Maybe I am wrong, but until a real user confirms that a "DUAL SIM FULL ACTIVE" phone really behaves like one, as in the first part of my question:
handling two calls simultaneously then I will accept the definition.
What the manufacturer/dealer/seller , or "tester" says, can be very misleading.

So, yes, more information is needed at least for me.

DUAL SIM covers me for the foreseable future, thank you very much!:D
 
V970 is not Dual Sim Full Active. The U960 is, and it works without problems (you can call your self on the other sim :-)

The U960 supports WCDMA on SIM2 and TD-SCDMA on SIM1.

I know that because I owned a U960 and have a V970 now (here in my hand).

No MT6577 chipset phones are DSFA, it is simply not supported by the MT6577 chipset. However both sims are online at the same time and can receive calls, also while using internet. Only when one sim is active in a call, the other one will be offline.

Thanks again EmilF!
The "FULL ACTIVE" feature may seem trivial to some users, but I will have to make sure that it is a real feature, if I have to end up buying a chinese phone with all the risks that come with it.

You are definitely a Hard Guy to get convinced of something !!!

No matters how many times anyone tells you something, you still don't get sure...

Cheers Man.
 
Samsung Galaxy Duos (Y, S and ACE) are some great full active dual sim phones. They sell really well and have a track record of beating user expectations. We have seen a bunch of people use these phones to to handle multiple phone numbers and they all seem very satisfied with the way the phone manages both sims.

O.K. EmilF (and other ZTE U960 users)!

Can you please list what a ZTE U960 need in terms of flashing/ROMs/SW updates, etc. to work properly in a European environment?
The Android version is dated and it doesn't look like ZTE updating it at all!

I'm not a U960 user, but I am a user of a Chinese smartphone. What can make it easy for good European use is to (1) ask for a custom PROM and (2) ask the phone be setup by default in one's native language, and (3) ask that Chinese apps be removed, and (4) ask that googlestore be installed.

For example for the U960, Etotalk, a Chinese supplier provide for an extra $4.99 a Etotalk MOD ROM that provides the aspects I noted. According to Etotalk their custom MOD ROM provides:
Etotalk website said:
What is Etotalk MOD ROM?

Now most of China branded phones come without google play store (android market) and only Chinese because they are for selling in China only, so they are locked and unrooted, if you need to use it well in other countries, you may select our etotalk mod rom.
Etotalk MOD ROM is built by etotalk engineering team, which will optimize the phone performance based on the official firmware.

The service package includes Multi Language OS, Google Play Store, Unlocked and Rooted. It will also delete all non-useful Chinese apps.

Note: this service is for preinstalled only, not including the rom file.

I suspect other Chinese suppliers will do the same.

Indeed Android-2.3.5 is very dated.

I agree. Samsung Galaxy Duos Ace is one of the best dual sim cell phones that I have used.
 
Thanks again guys!

After some research, I think I 'll have to pass the ZTE U960 and make a compromise with the "full active" feature.
I have the following in mind, so whoever has any experience with any of them please comment:

Huawei U8836D

ZTE v970

SAMSUNG GALAXY S DUOS


By the way, I noticed that this thread is by far the biggest in the androidlounge: 1,687 posts and 496,625 views!!

Do the mobile manufacturers do serious market research???:D:D:D

Can you tell me why you decided to pass on the ZTE U960? Is it because of the dated Android version?

I am in the same boat looking for a suitable android dual sim after having used samsung B5702 and C6112 for a while. Dual sim full active doesn't seem to be an option in android versions.

SAMSUNG GALAXY S DUOS

I have none of these phones. I did look at their specs, liked them all, but in the end went with a phone with 850MHz 3G, which meant I could no longer consider those phones. Still, I had this in my notes (price is an etotalk price - there may be cheaper prices on the web - I put the approximate price in only for relative comparison purposes between phones):
  • Huawei U8836D, dual core, 4.3" display (540x960), gorilla glass, 1GB RAM/4GB ROM, camera(s) 5.0MPixel back/0.3MPixel front, 1930mA battery, ~$219.99
  • ZTE V970, dual core, 4.3" display (540x960), scratch resistant (?) glass, 1 GB RAM/4GB ROM, camera(s) 5.0MPixel back/0.3MPixel front, 1600mA battery, ~$179.99
  • Samsung Galaxy S Duos, single core, 4.0" display, (480x800), gorilla glass (?? < not sure > ), 768MB RAM/4GB ROM, camera(s) 3.0MPixel back/VGA (0.3MPixel ?) front, 1500mA battery ~$239.99
It was clear to me (in my research) that one is paying more $ for the Samsung name for a more expensive phone with quite a bit less capable performance. I guess the question is, by going Samsung does one get better support/quality ?

Out of curiosity, did you consider the Newman N1 ? My guess thou, the Newman N1's quality of build may not be as good as the phone's you listed. But it does mostly have the equivalent specs at a cheaper price.
 
Changed my Desire V to Samsung Galaxy S DUOS.

The hardware is neck to neck but the DUOS edges out with slightly more fluid software. It is also on Samsung s upgrade list to Jelly Bean. It has one of the best dual Sim management system i have used so far, quite a pleasant surprise really. Despite having a smaller battery than Desire V, the DUOS battery life is outstanding - i have gone through days of standby with light use on dual sim active. And for Europe based people, it s on sale locally with EU wide warranty.

I can only hope now they ll also bring the Galaxy Note DUOS out soon.

Hi Kingcedz,
Do you have any further update/comments to make on your experience on Samsung vis-a-vis the HTC? A qualitative feedback on what you feel is good/bad in Samsung/HTC would be very useful.

Have you used ZTE/Huawei/Newman/Lenovo to make a first-hand comparison?

Many thanks
 
Stop Press:

The best are now the MTK6577 based phones. The GPS is slow and the build quality is poor but I can attest that they are very good for the money.

The only thing is... you can buy my X710D off me because I went for a massive 5" screen intending it to be a tablet/backup phone and then had my main phone stolen!

The other thing is which is a major bummer is no kernel source but if you don't hack around it's the best imho

Yes, it is clear that you pay more for the support of the manufacturers and you have their guarantees, as long as you don't mess with their product.
It is interesting though, that as far as the DS phones are concerned the SAMSUNG Galaxy S Duos was officially announced and released only in Germany.It is on sale in other European countries also, but they are nowhere in the respective official SAMSUNG pages! Here in Finland the phone is not on sale (actually very few DS models are and they are of the older types).
I called the local official SAMSUNG rep, to ask about whether the S Duos will be released in Finland and the answer was that.... they know as much as I do!!!In my question if they support this model if it's bought from some other country, their answer was that as long as there is a valid international guarantee for the product, they fully support it.
I haven't been able to contact other brands yet.
Out of curiosity, did you consider the Newman N1 ? My guess thou, the Newman N1's quality of build may not be as good as the phone's you listed. But it does mostly have the equivalent specs at a cheaper price.

No, I haven't consider it as it is completely unknown to me.

Yes, I guess it is.Plus the fact that it is more expensive.

A number of Chinese suppliers sell the Newman N1. I first read read about it on Etotalk's site. Specs are good for the price:

  • Newman N1, dual core, 4.3" display (540x960), gorilla glass, 1GB RAM/4GB ROM, camera(s) 8.0MPixel back/0.3MPixel front, 1700mA battery, ~$169.99

... but I could find nothing on the Internet about the company that produces it (in English - I did find a Chinese website: http://bbs.newman.mobi/portal.php). In contrast to ZTE, Huawii and even ZOPO where there is a fair amount of information on those Chinese smartphone suppliers. Hence I would be worried about quality. There is a very long thread about it on XDA-Developers: http://forum.xda-developers.com/showthread.php?t=1888501 ...

The Newman N1 did not have the frequency coverage for North American 3G that I was looking for (850MHz) so I struck it off my list for that reason, and I did not pursue further checks into the quality of the phone.
 
I have been following this thread for a while and I have fount the information provided by the other members informative and valuable. So, thanks guys!

I decided to buy the Huawei U8836D based on the specs and other people's recommendations. I've had the phone for four weeks and I am very happy with it. It is responsive, solid with good battery life (two to three days, depending on usage).

I ordered my phone from Etotalk based on their good pre sales service and I was pleasantly surprised to see the phone on my door step 10 days later! I live in Australia by the way.
However, two application I had requested were not installed. I emailed them and they asked me for a photo! I emailed them back several times and after "mentioning" that I would alert other buyers about their lack of service, they decided to act by sending me links to one of the missing apps with, hopefully, more to follow soon.
I am very happy with my "toy" and I would not hesitate to recommend both the phone and the overall service from etotalk to other users.
Thanks again!

Have you checked if the SIM menu of U8836D can be configured in an "always active mode" in order to be able to receive calls to SIM2 when you are on a call on SIM1, like in Samsung Galaxy S7562. Of course you need to activate call waiting in both SIMs and call forwarding (with the charges of your provider of course) from SIM1 to SIM2 and vice versa in order to have it working from the SIM menu.

Also does it support Skype video calls?
Thank you.
 
Great discussion about Dual SIM phones here. I have Samsung Galaxy S Duos GT-S7562. I am quite happy about it.

Here I would like to advice the users who are exploring various devices to check SAR value of the set beforehand. One of the reason that I chose this model that it's SAR value is well below many preferred single SIM phones.

My 2 paise.
 

It's certainly an interesting thread.

Etotalk are supposed to be one of the few apparently reputable Chinese wholesalers. But at the end of the day, it's still caveat emptor. So if they refuse to honour the warranty or turn round and say it's only three months warranty for the screen....tough luck!!...you're on your own. Trading Standards or Better Business Bureau won't be able to help you. This is what can happen if you buy phone from Shenzhen, and not Best Buy or whatever.
 
Now What Noir A10 is gonna be like ?
