Microsoft Lumia 640 LTE Dual SIM - User Reviews

  • bad phone with no good cameras

  • Better save your money and buy BLU Win HD LTE. It supports upgrade to Windows 10 Mobile too and has a better processor. It cost just Rs 4500 in Amazon and add the cost of Nillkin 2A charger the total cost is just Rs 4999.

  • I recommend "Monument Browser", it is far better and more stable than Edge on my Lumia 640!

  • LTE support mbile

  • Is the Microsoft Lumia 640 lte will also insert 4G sim ????

  • Phone works well. Not the fastest in existence, but functional. There are two features which it will not perform.... It will not USB tether a data connection, will only hotspot or share data by bluetooth. Also it has only one 3G/LTE radio, so if one sim is connected at 3G or LTE, then the other sim will only connect at 2G. The problem in Australia is the 2G networks are being decommissioned. Telstra already has decommissioned, and Optus and Vodafone will during 2017. Needs two 3G/LTE radios for proper dual sim function.

  • Is it available in india? where?

  • After updating windows 10,battery backup becomes very very poor.Then after I degraded to windows 8.1

  • Uhav no idea about applications ...still win 10 update not available in India. here maps also not working properly ..its better to bring another phone..Good bye Microsoft..at least focus on laptop versions

  • Is the Dual SIM 640 LTE finally coming to India? MS take ages to launch the phone. Saw zauba listing of RM-1075 imported around 28th March. God knpws when they'll launch this phone

  • install Upgrade Advisor and check if you are eligible for Windows 10 upgrade. If it says yes, then you'll be able to upgrade to Windows 10.

  • If you do not like Wp 10 you can always go back to WP 8.1 using "Windows Device Recovery Tool" from here

  • Many countries, Sweden..., do not yet have the app "Upgrade Advisor" in the Store!

  • I have installed the app "Windows Insider" from the Store and used it to install Windows Phone 10 on my Lumia 640! WP 10 is a disaster just as Windows 10 for laptops...! Still no Cortana, no "quit hours"..., in Sweden, and the swipe-gestures for back and forward in the browser is gone, and HERE Maps will be gone in june 2016, and the compass do not work when using Windows Maps! The app I used to stream the latest movies have stopped working, and there is no PopcornTime for WP 10! This was the end of WP 10 for me, GoodBye Microsoft!

  • I've got the windows 10 mobile upgrade this morning on my lumia 640 lte ds, im in french guiana, first download the microsoft's upgrade advisor and follow the step

  • Does anyone get windows 10 update already?

  • Does anyone get windows 10 update already?

  • My mobile not supported to 4G voice calls please support me

  • Otg connect my phone

  • Does lumia 640 xl LTE dual sim support otg USB cables & pendrives

  • Got a brand new one couple of weeks back. On the 2nd day got the 1st issue. 1. No voice(speaker or headset) when calling. Did a factory reset, worked for a day and again the same issue. 2. Suddenly some data(all the mp3 and videos) from the microsd was not recognized. Video clips recorded from the phone also not recognized. And I did an internet search and there are threads created by other people regarding theses issues too. Really love Lumia but they keep letting down the users.

  • Most regrettable, 640 could not receive first update to 10, and launched 650 with minor upgrades and no XL version nor dual sim. MS gone nuts with a lowest Soc 215. No need just wait for Nokia to comeback by 3rd qtr and see who dam care.

  • Can you please tell us if the Microsoft 640 LTE Dual Sim that you bought from USA, as you told us, work smoothly here in Greece, as well as in the USA ?

  • I would like to buy a mobile phone with the following technical characteristics: 1) Networks - GSM, HSPA, 4G, LTE, 2) Screen - 5 '' 3) Processor - Quad-core 4) O/S - Windows or Android 5) Memory - Internal 8Gb - External 64 Gb 6) Camera - at least 8 Mp / 1 Mp 7) Dual SIM 8) Battery - Removable, at least 2500 mAh 9) Language: Be able to write / read SMS in Greek language and in English 10) Automatic screen brightness adjustment 11) Enlarge fonts which can be operated in Greece (providers: Cosmote, Wind, Vodafone) and in the USA (providers: AT & T, Verizon)

  • i recently bought Microsoft 640 xl lte . yes it is best phone . but reliance jio sim is supporting only data not voice call with this phone ..that is it....overall operation is good. my [email protected] thanks

  • Try Windows 10 really good for thus phone 😆

  • Why r u this type of communication you have not knowledge in windows segment plz yu used only android plz u don't go with windows os

  • It'll work in VOLTE phones only.

  • Well they already released it, it is now called Lumia 950XL.

  • Got one like this after my Sony z3 compact cracked in accident (RIP dear, you were not the best, but one of them), so what can I say? Now I understand why Microsoft phones market share are so small, it's terrible, it's awful, guys do you really think there that this peace of cheap plastic and useless software in it can satisfy anyone???

  • I am having Lumia 640LTE Single SIM & Why it's not supporting Reliance JIO 4G SIM. As per the specifications it's suppose to support requesting for help.

  • Dear Microsoft Please stop making Orange, Blue, Green and multicoloured phones.

  • Yes, they both are 4G capable. And yes, there is a microSD card slot.

  • Lumia 640 lte is not available in india and many service center and stores have been closed by microsoft in india.so you can face service problem and the no.1sold model lumia520 has been facing many kind of problems in india just after 2years so life of lumias is not good as past nokia's sets.it is very sad that microsoft lumia 640 which gave some fight to bunch of androids is not available freely in a fixed price and there is recently service is not available for problems of past purchased lumias.so problems are for both sides and don't have a lollypop of windows10,because it is for behind to android5.1to 6 in multitasking.there are only average performer lumias are available in market freely like 535,540and 640xl but not 640lte and 640dual sim.In my opinion microsoft never would be in top three in future.so friends don't go for lumias...they are costly and their good models are not available in india and now there is service problem also.thanks to read it

  • Are both SIM cards capable of supporting 4G? There is also a slot for additional micro SD card?

  • Best phone in the market with lots of features for reasonable price.. I have used Lumia 800 , Lumia 925 and now Lumia 640.. Comparison.. Good -- --Screen size has increased --CPU, GPU and Chips upgraded --Micro SD supported --Battery life increased and can be replaced --Gorilla Glass 3 available --Dual sim supported --4G LTE, NFC, GPS, WiFi, BT available Bad -- --Display has downgraded to AMOLED to IPS-LCD --Carl Zeiss lenses missing --Gyro sensor is missing

  • Help me to check sar value in Microsoftlumia 640 dual sim

  • This is not a problem.. its the charging way of latest models ..

  • Just android Just nexus

  • YAY you and me are the only normal persons that look at SAR!

  • What is the sar value?

  • Go Microsoft.com

  • Noticed, Lumia 640 LTE is listed in Microsoft India Website... Looking forward to get this as an upgrade from my L520.

  • Sometimes people speaks with nonsense. The smartphones come in different sizes. From there, you can choose what you like for yourself. What do you mean by you don't want a tablet for a phone? Some people like small size while others like big. Use your common sense.

  • LTE is a prosasor which can upload and download faster price-11999(rs)

  • Lumia 640 LTE dual SIM might not be launched in India as Microsoft website doesn't even show it with coming soon tag

  • Considering the price, one can't really complain about the abscence of Zeiss Optics, oh and by the way do they make any difference ? I don't think so, I've compared them myself and it doesn't seem amazingly higher as you expect it to be, don't forget this is a mobile phone not a DSLR so whatever technology they'll use the image you get will still be of an average but decent quality.

  • Never heared of it .. Anyway, if such a model exists I don't think they'll launch it soon, they're still getting good sales on the 640 XL so why launching a new device before maximizing profits over the actual one.

  • SAR ? ? ?

  • when microsoft is going to launch 940xl

  • Hello there, I am from India and Microsoft has got LUMIA 640 Dual Sim available only online. Since 4G is launched by couple of service providers (carriers), when Miscrosoft is going to launch Lumia 640 Dual Sim LTE in India?

  • I guess that's why Elop got fired.

  • Same problem here in Tunisia, the only version that I can find is the XL one which is huge and not easy to handle .. Microsoft is having a very strange Marketing strategy !

  • i have more of a question than a opinion, you see my device drops connection out of the blue its not regular but its happen once in a while. is it normal or should i do something.

  • never by it it has call bug softwear bug

  • Does anyone have issue with sensors or their software on this model? On mine every 1-5 days without reboot sensors crashes causing fitness applications stop working (e.g. to stop counting steps). Reboot helps.

  • To big looks funny for a a phone, XL verison silly, stretch fingers to type. 4.5 should be max phone imho. Market goes to crazy at times, i dont want tablet as phone.

  • how many hours we should charge on First Battery charge ?

  • i am looking for lumia 640 dual sim 4g lte any one assist me where can i find

  • I'm more concerned about the back material and hate to have a cover for a mobile. Need to know if anyone has the Matt-Black Model of this mobile. Need to know if the overall finish of the back-panel similar to that of the Nokia Lumia 520's if anyone may have seen/handled/used it earlier.

  • LTE model means lte support. Only dual sim comes with 3g only

  • Try eBay. I got mine from,there

  • This was good information, to buy in US if not available in home country. Is there any online website is available to do this.

  • What is the difference between Microsoft Lumia 640 LTE model and Microsoft Lumia 640 Dual SIM ? Is this a same model or different and what are the difference in between those device.

  • Which says 640 LTE

  • Which one is 4G supported?

  • Please note all the models are not avaible. As i bought one from USA dual sim lte as j my country only xl is aviable. So u have no choice unless waiting or biying like me

  • The front camera is capable to snap at 720p. So its not a big deal and its great phone

  • Yes both, and its greatphone i kove it

  • Microsoft the 5' 4G dual sim 640 LTE phone is released in other countries why not in India.

  • Its not a problem it doesmlnt charge in switch off mode same is with ios it also doesnt charge in switch off mode.

  • Does it support otg and tap to wakeup?

  • Microsoft values privacy, that's why I didn't include call recorder.. But I don't understand why that was included in wp7

  • I would Like to Purchase this Phone But i felt one small defect in this phone that is Front Camera is 1MP only

  • The last Lumia I used (Lumia 710) could not send ussd codes. what about this one? Please help.

  • In the german Model LTE is not working/active so bad :-( Why Microsoft do this ?

  • specifications are impressive. . n front cam is jst 1 mp... this is d bad thing in this phone.... :) (ˇˍˇ)

  • When will this phone avaiable in indonesia?

  • First your create an a/c in the microsoft site.Then you can download all applications.

  • No, for selfie lover. Go for other 5 MP front Lumias.

  • In Windows Phone 10 is going to have call records. I've got a release preview on my Lumia 620.

  • I'll only buy further windows phones if they have call recorders. There are important calls which records a caller has to keep but windows phones manufacturer over the years has refused to make phones with call recorders. This is quite absurd. I used call recorders when I was using Nokia-based symbian phones. I don't know what excuse MS will give for missing this important programme.

  • Where it is available ?

  • Its mentioned that , the model is available since April 2015. Please mention the store names, where it is avalable?

  • This is normal for Windows Phone. You can always set your phone to flight mode during charging if you want.

  • Guys I am facing a problem in my newly purchased phone.When I am trying to charge my phone on switched off mode , phone automatically get turned on. Is this a problem with my phone or it happens in all Microsoft Phones? (Earlier I was using Nokia lumia 520 and I didn't face any problem like this). Please help. Thanks In advance.

  • Iam unable to download any application in this fone.pl tell me the clues to down load applications from store

  • wt abt d frnt camera...is dis ok fo selfies..only 1 mp ..pls tel ..is it ok

  • No need for Screen protector, already Gorilla glass 3.

  • It's Gorilla Glass. Y do u need screen protector???

  • when is it coming to kenya i love the 640 3g DS

  • Has a Lumia 640 LTE Dual Sim last night. It is great at a compatible price with LTE feature. Microsoft did a wonderful job. But I would like to find a case for it and screen protector. Any advice?

  • Hi all , A friend of me is on germany and he found lumia 640LTE/730 at the same price i like more lumia 640LTE Because it's new product with microsoft logo and 730 looks a little oudated for me , specs are pretty smilar , Lumia 640 has IPS LCD and 294 ppi are enough for me i'dont care about oled display , Ips cld is great for me , also battery is better on 640 LTE Perfect mid-range budget phone for me , but i have a afraid that front camera is not good enough to take a good selfie on any kind of condition 0.9 MP looks bad in peaper for me , am not a selfie lover but sometimes all of us want to take a good selfie it's seflie world , i'dont see any good review about lumia 640 front camera so can somehone sure me that lumia 640 camera is good enought to take good selfies on all conditions like light etc , I hate that front camera of lumia 640 to be the reason to buy another phone like 730 or other 640 for other specs for me is great just worried about that , thanks all.

  • ITs good to hear its available in USA, how about INDIA. There are so many models for Lumia 640, we should make sure it supports 4G LTE network.

  • lumia 640 Lte dual-sim is now available in US for $220

  • Reason why I bought this phone. There's only two variants available in Malaysia XL dual-SIM 3G & dual-SIM LTE. Although the spec is a so-so, I don't like extra large screen. So, I have to deal with the lowered spec. It's good that I don't use camera as much so the issue solved. I'm also worried that with the only plus 500 mAh, how long can the XL variant hold? And using the same processor, I thought having a smaller screen might relieved some processing burden. Especially when the beefed-up Windows 10 will be installed later.

  • That's 640 3G for sale, u can easily check the Uk MS store mate ;-)

  • how long to wait for this model. feeling enough of waiting. when Windows 8 or windows 10 reaches end of life, it will be outdated model

  • That phone is already in MS Store online in UK for about 169 pound as i recall from last check Mate. Go see for Yourself. LTE Dual SIM, not XL :)

  • hi guys, I think 640 LTE dual-sim is the best choice among the other versions but there is no sign of it anywhere; it's not available yet. The only LTE version is 640XL which is available in UK for £210

  • Dearest friend.I myself prefer lumia 640 XL LTE for superior qualities!Please test in research in local stores before buying any devices!?Also please don't hurry and wait for gsmArena review to find advantages and disadvantages!?No review means cheap quality devices!!!Thanks.

  • hello friends plzz tell me about this phone hows is this its best phone or nt if u alredy buy.... thanxxx

  • Ok I am back here..... Again rethinking about lumia 640 dual 3G. Hey Surin and shuvo what's up. Ok now I request and recommend to those people to post here who have bought it. If you have pic taken by lumia 640.then please post the pic to me on my whatsapp no. 09451452509

  • what is the best phone on that price this one or anyother

  • Yes it will, after upgraded to Windows 10.

  • this device supports OTG or not?? please tell me ...

  • Dude 640xl dual sim and single sim have 13mp Zeiss optics back cam and 5mp Frnt cam.. Only the lte model of 640 and 640xl won't be released in India.. U can buy 640xl dual or single sim which has 13mp and 5mp.. Price 15600..

  • 4G/LTE support model is not available in India still now. Camera with carl zeiss lens is not there. Front camera is 0.9 Mega Pixel.So not suitable for Video Calling & Selfie.

  • You are correct my friend,LTE versions are not yet released in India.Also mocrosoft has not said when it will going to release.But anyway thisLumia 640(3G) price is too high.Its not worth 12K from any angle at all.I woud have expected Lumia 640 LTE version to be 12K but not Lumia 640 3G set.Ms disappointed again.

  • Microsoft Lumia 640 launched on 7th April 2015 but not LTE. Can anyone tell when LTE will be available in India. Please reply.

  • will be its display better than nokia lumia 730 with oled display.

  • I love the specs of the phone but the rom should have being more than that.Anyway,i give microsoft a 9 out of 10

  • please tell me about lumia 640 it is touch is sensitive or not

  • I want to know will this phone age with grace or it will it's value in due time?

  • Good phone,, but i think 4.5'' would have been extremely appealing

  • is this phone with feature static ip in wifi ? many lumia like lumia 620 with latest update also not having this. so i am not getting wifi in my office as it allows every mac address with a different ip. please anyone using check and mention

  • what about front camera

  • Will it be available in Bangladesh?

  • wp10 has this feature ,wait

  • plzz ant one helppppp

  • Will be available when you upgrade it to Windows Mobile 10

  • Max i am avilable to see fitures but one think is missing that is (OTG) does the lumia phone supports it pls replay

  • Its short for usb On The Go, where you can use a flash drive directly on the phone using an adapter. This feature will let you manage your media/files with your phone instead of a pc

  • Please launch in Pakistan (LTE Model). I search most of the Pakistani's people are awaited for this LTE best Phone.

  • Microsoft is waiting windows 10 to release flagship phones

  • What does Microsoft is waiting for now

  • yes ofcourse it has better camera with carl zesis lens

  • Is it have better camera than 730 Can it be a better option than 730 or not

  • please tell me does it has KeyPad option in keyboard?it's hard to type on keyboard

  • Because it is a lower budgeted phone than the 640XL. If it is going to be using the same camera, why bother to have a 640? You should be happy that the internal hardware are identical. Snap 400 is not a bad thing for Windows Phone. A very old 1020 running Snap S4 is still performing good. Snap 400 will be snappy enough for the OS and its apps. Furthermore, it is already equipped with 1GB ram - no need to wait for 512MB supported games anymore with this phone.

  • USB OTG - plugging in a thumb drive via a USB cable connected to the phone and read from it. Android does it.

  • Is der also same problem as dat of lumia 535 touch sensitivity??guys plz tell me...

  • What is USB OTG?plz tell me

  • if priced sensibly then instant hit ....

  • i'd really wish that the next one would have wifi direct. that would be a big boost because it is so fast and i actually use it for most of my file transfers. this will also give it a level playing field with other devices that already have the feature.

  • wahy flagship phone.?

  • gud phone and plz get same features in 4.3 r 4.5 inch screen. .plz

  • I remember some news about counting on OTG support on the Win 10 echo system.But there is no official statement that clears in which build No. It will be take place. In my opinion using or not using a lumia device is not dependent on supporting/not supporting simple features such as OTG. The most important meaning of announcing these non flagship smartphones is to gather more lumia users than fullfilling the simple desires of old lumia users.We should be better to wait for a flagship in couple of mounths.

  • Don't expect too much, this is not a flagship phone.

  • Now it not supported USB otg ! But in next update windows 10 phone it will support USB otg

  • Does it have carl zeiss 8 mp camera or any other

  • It will

  • Look at the price and check who else is providing that with such a low price. You'll have to look at the whole package

  • welcome to the world of microsoft.

  • No,Dose't Support OTG

  • Can anyone check if it supports USB OTG

  • Nice phone, go MS

  • wp 10 is the future of tomorrow

  • first of all thumb down for old 400 chip. 2nd thing y dint they use carl zeis lense in 640 lyk 640Xl. there's always going to be lack of some feat. thats what i hate microsoft. such a disappointment after so much for excitement.

  • Expected price Rs. 12000/-

  • only 8 GB, no Dolby HP, FFC only 1MP.

  • Perfect Configuration from Windows Phone.

  • Super affordable phone

  • What's may be the price range?

  • Super phone

  • Will it support 4G in India?

  • Was waiting for this. Finally. But I think Lumia 640xl will be better I guess. Windows the no-nonsense clean phone. I'll be buying the 640xl version the moment it launches in INDIA. Love ❤ you WP.

  • Nice phone , go MS
