    So is there a definitive answer on this? I see a phone on Expansys and on ebay that list the following:

    LTE FDD network: Band 1 (2100 MHz), band 17 (700MHz), Band 2 (1900 MHz), band 20 (800MHz), band 3 (1800 MHz), band 4 (1700/2100 MHz), band 5 (850MHz ), Band 7 (2600 MHz), band 8 (900MHz), band 28 (700 MHz), band 12 (700 MHz)

    TD-LTE Network: Band 38 (2570-2620 MHz), band 40 (2300-2400 MHz), band 41 (2555-2575 MHz)

    Its calling out the LTE bands, but it is not listed as an LTE phone.

    Thanks.

    Hi All,

    My 640 XL Dual Sim is on its way and it will be here tomorrow. It is now readily available on EBay for $249. It is RM-1096 version.

    BTW Outside US 4G = LTE. Hence all phones made for outside world will show 4G for LTE speeds.
    Thanks for the explanation, MUCH appreciated! I also reviewed the manual for the phone (which is a generic manual for WP 8.1 update 2) and it doesn't mention LTE anywhere, which also supports your statement. It just states '4G' for '4G networks' which technically is inclusive of LTE.

    I have received my 640 XL dual sim LTE and it works flawlessly on TMobile and AT&T sim. I have a Vodafone India sim which I use as a roaming sin in US and it roams on the TMo and At&T just fine. Tmo LTE speeds are fine. The phone does support the 14 different LTE/4G bands

    What does LTE or 4G speed mean? When my phone shows 4G (Tmobile USA in NYC), according to Microsoft's Network Speed Test app, sometimes it can be as fast at 30Mpbs download or crawl to just 2-3 Mpbs, and when it's that slow, it still displays 4G. Sometimes the data connection does switch to H or H+, but most of the time it shows 4G and I get this vast range of download speeds.

    It depends on the network quality not the network strength. Sometimes it may happen that network is full but the quality might not be good. Here in Mumbai also, I get full 4G strength but when in hope 20mbps and outside is 27-28mbps

    For those in the USA, according to the Wikipedia ( List of LTE networks - Wikipedia, the free encyclopedia ) , the LTE bands supported by the big 3 carriers (Verizon, ATT, Tmobile) are 700 MHz, 1700, and 1900, which are not the LTE bands supported by RM-1096 version of the 640 XL ( Microsoft Lumia 640 XL LTE Specifications - Microsoft - Global ), which are 800 MHz, 900, 1800, 2100, and 2600.

    My average download speed varies mostly between 6-19, very rarely does it get anywhere close to 30, however, this seems inline with a March 2014 test of LTE speeds in NYC by laptopmag.com : http://blog.laptopmag.com/fastest-4g-nyc which implies that my RM-1096_1001 on Tmobile USA does support LTE.

    Correct link for rm-1096 is below. Based on that, 1096 does support US LTE (and mine does work well with TMO)

    That explains why my RM-1096 gets Tmobile LTE, thanks.

    So I guess the final answer is: the 640 XL LTE Dual SIM may actually be on a 4G LTE network, but will only display '4G' as the network on the top of your screen?

    I get LTE on both ATT and TMobile on my 640XL DS LTE from HK. It only shows 4G but does get LTE speeds.

    Manufacturer Name RM-1096_1001.
    Mobile Operator: 000-HK

    That makes sense. If you use a non-US phone in the US and see 4G you are getting LTE. Thanks to US carrier marketing dolts for corrupting what 4G means.

    There are two models from Microsoft in the Dual Sim format. The RM-1065 and RM-1067. If you live in the US and are on AT&T or T-Mobile you need to get the RM-1065. The RM-1067 is 3G or 4G only.

    B&H Mobile has both models. The 1065 model is about $50 higher. Received my 1065 today and I am getting full LTE speed. Speedtest shows download speeds over the network at over 13 Mps and upload speeds slightly lower. Specs also show that the 1065 has all the LTE bands in the US.

    I started a new thread about this, but that's the first time I'm hearing RM-1065 being dual-SIM. Are you sure about this : under settings -- > extras+info, under "manufacturer name", can you please give the full RM number? And have you verified there are two SIM slots?

    Thanks,

    Thank you for verifying. What's the difference between 1065 and RM_1096_1001, the one I have? Mine is dual-SIM, LTE, on TMobile USA and getting 4G connection.

    I think the 1096 is just the international version, which is also the one I have. I installed the 'Net Check' app and it definitely identified me as being on a 4G LTE network.

    newegg just got the RM-1065 version in stock, unlocked.

    Does that mean the LTE band coverage is different? It seems both RM-1065 and RM-1096 cover US LTE bands.

    To get the LTE speeds in the US you need the 1065 variant. The 1066 and 1067 will only get you 4G.

    Is that a typo? Did you mean 1096 instead of 1066? Why would the 1096 NOT get 4G LTE in the US? It operates on 1700MHz (T-Mobile) & 1900MHz (AT&T) bands which are both 4G LTE.

    Unless you are referring to the non-dual sim, which is 1066 and not LTE or 4G, in which case it is NOT a typo... and the more I think about it, probably not. Haha.

    I bought the dual-SIM international LTE version of the 640 (non-XL) and it rocks LTE in both Canada and the U.S. I'm quite confident it'll work.

    Did we ever get official confirmation that it can do at least 3G on the second SIM through duplexing? Or is it 2G only?

    I have a 640XL 4G LTE Single SIM RM-1064_1017 bought from Vodafone Australia, it has 2 sim slots however one has been blocked off with a fixed plastic block. When I updated the software to Windows 10 and then reverted back to Windows 8.1 update 2, I now have 2 phone apps with one being marked as Phone Off. I am assuming the software is picking up the 2nd SIM slot but I do not know if it would be possible to remove the plastic block and activate the 2nd SIM slot. Wouldn't the phone need two 4G LTE Radios for both SIMS to work and if so why would the software pick up the slot if no 2nd Radio would be present. Could understand making one board for both phones to save costs but surely they wouldn't include 2 Radios and just deactivate one???

    I think that that is just one of the peculiarities of Win10 being so beta. When I installed Win 10 on my Lumia 635 it also showed two phone apps (and is definitely single sim).

    For those concerned about connection speeds the best download speed I have seen (using the speedtest.net app) is 55.98Mbps and upload of 12.66Mbps my carrier is Comviq Sweden. Phone model is RM1065_1012 version 000-FR (French market dual sim LTE)

    Hi Mike, when you're on an LTE network, does the 1065 say 'LTE' at the top of your phone, or just '4G' like the international version?

    It says "AT&T LTE.".

    Go to B&H Photo and pull up the RM-1065. Go to the Specs tab. It has ALL of the AT&T and TMobile LTE bands.
