I intend to buy a Droid 2 Global and re-programme it for my network in Nigeria (Visafone). I've done this successfully for a couple of CDMA phones; I know what I am doing on that one, but I have a question. I see that the Droid 2 Global is a dual mode phone GSM/CDMA. Is this like the BB Storm 2 or is it dual standby, like both networks work at the same time just like the Motorola XT800? I've been searching for a dual mode, dual standby Android phone and I figured I would go with the Droid 2 Global, if it is really dual standby. Please can anyone help me clear this up so I can make a decision about buying the phone on ebay.
Thanks everyone.
The A956 (D2G) only has one transceiver that can work in either GSM or CDMA mode. In Global mode, CDMA is preferred (if there's CDMA reception, the phone will use CDMA).
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.

Hi,
I've ordered an Elephone P8 based on the MediaTek MT6592 SoC . It's really a great deal. It works fine on my carrier, T-Mobile, for voice and text, even a little light Internet audio streaming, and "full bore" on WiFi. when I need some mobile data access I "Hotspot it" with my old HTC G2, which I keep in my bag. Which works well on the go.
As many of you probably know though, this phone's frequency coverage, doesn't allow for it to directly access one of T-Mobile US's data frequencies, namely, I think, its 4G/LTE 1700 Mhz frequency.
Now, ideally, I'd like to just slap the T-Mobile simcard in the P8 in the Elephone and have it work straight away. While the Elephone P8 itself doesn't support the frequency, the MediaTek website lists the following support for the MT6952:
Features:
Octa-core (1.7GHz or 2GHz) ARM Cortex-A7 processor
ARM Mali GPU
UMTS / HSPA+ R8 / TD-SCDMA / EDGE / LTE
Dual-band 801.11a/b/g/n, Bluetooth, GPS, FM receiver
Full HD display controller
16MP image signal-processor
H.265 Ultra HD video record & playback
Which makes me think, and I am, admittedly, not very experienced in these things, that the Elephone is "capable" of the frequencies, as bolded immediately above, but that they have "dumbed down" the chip via software to prevent interfering with American markets.
So my question is, is it possible to modify the firmaware to enable this/these frequnecy(ies) to enable full capabilities on the T-Mobile US networks?
I've looked at some of the available P8 ROMs, but can't determine if they are capable of expanding the device's capability to do this, or if it is possible. If anyone has any thoughts about this or, even better, has a more definitive answer, I'd love to hear it. Any thoughts would be greatly appreciated.
Thanks for your time!
Although the Mediatek website hints at LTE for the MT6592, none of the multitude of MT6592 phones released to date support LTE. LTE on MT6592 phones would require additional modem hardware that would be uneconomical. For LTE on Mediatek you will need to wait for MT6595.
BTW I'm looking forward to receiving my P8 in the next day or so.
This is incorrect. Sorry but I have in front of me a SHAX SX198C with mediatek MTK6592 and it has full 4G LTE functionality working no problems. Also I will take a full backup image of the SHAX current ROM and I will be trying to Port across something like the Elephone P8 to this device and hopefully maintaining that 4G functionality. If you would like the image for the SHAX to do any comparison or testing with send me a PM and I will gladly upload. I am going through this process now. I am new to these new China phones and this device is not mine, it is a customers. Thanks
Hey guys! Not new, just a new account. Recently purchased two new blu phones, a Vivo XL and Vivo 5. The Vivo 5 is my phone and I'm running dual sim with good results. I'm looking for info in regards to coverage with different networks. I know some blu units are missing certain LTE bands and I believe this is one of them. On AT&T the download and upload speeds are significantly slower than the speeds offered by T-Mobile. Does anyone have any information about this? I'm in CT and I'm not familiar with this kind of technology. AT&T obviously has better coverage, but lacks 2g. I want to use my second sim as my main data connection because I can switch to the cheaper plans as they come out.
If anyone has any information, I'd appreciate it!
I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...
If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.

3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.
4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.
