    Tmobile would already be selling it if Microsoft would have released it to them.
    I have no idea whether MS has to release it to T-Mobile or not, but I have to believe that if T-Mobile said "Can we sell this today?", MS would say yes and that MS isn't the hold up.

    I wanted to get a Lumia 640 for a family member in June. When it was announced March 2nd I thought for sure there would be US availability by then, 3 months is a pretty long time in the wireless industry after all.

    But here we are on May 12th, two and a half months later, and nada. What's the hold up? Will this phone ever release on a US carrier?

    Microsoft is losing the business with phones. Waiting so long for one to appear in the market! Ridiculous. People switch to other phones.

    I just bought and unlocked/unbranded 640 brand new on eBay for only $201 w/free shipping. Can't beat that. They have 3 left I think, I went with black.

    Cross reference the specs with your carriers operating bands:

    • GSM network: 850 MHz, 900 MHz, 1800 MHz, 1900 MHz
    • GSM max data speed DL: EGPRS 296.0 kbps
    • GSM max data speed UL: EGPRS 236.8 kbps
    • WCDMA network: Band 1 (2100 MHz), Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 5 (850 MHz)
    • WCDMA max data speed DL: 42.2 Mbps (Cat 24)
    • WCDMA max data speed UL: 5.76 Mbps (Cat 6)
    • LTE FDD network12: Band 17 (700MHz), Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 5 (850MHz), Band 7 (2600 MHz), Band 28 (700 MHz), Band 12 (700 MHz)

    be careful -- if they got that phone in Europe it wont work here... they have different supported bands...

    if you receive it AND it works... please post that information on here - in this moment, I will immediately order one.

    Not necessarily true. I checked the bands on a 640 for sale in Norway and it's the exact same bands that are available on the phone here in the US. Yes, the bands used in Norway are not the same as here in the US, but this phone supports enough different bands that it does not seem to matter where you are.

    We had a couple of weeks ago a thread on here, which pointed out, that it is NOT be compatible with ATT ...
    AT&T | What You Need to Know About Your Network

    "We currently use frequencies in the 1900 MHz and 850 MHz ranges, although we have licenses to operate in other ranges."

    What are AT&T's 4G LTE bands?

    "LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently."

    "The 1700/2100Mhz (AWS-4 or AWS Band 4) requires both the 1700Mhz and 2100Mhz frequencies to be used at the same time. The 1700Mhz is used for uplink while the 2100Mhz is used for downlink."


    So from where I sit, the 640 supports all of those perfectly. I'll know soon enough once my phone arrives and I use an adapter to put the nano sim from my AT&T 1520 into this new 640. I 99% bought the 640 to use on Digicel though which uses 900 MHz and 1800 MHz so if for some total fluke it won't work on AT&T, I couldn't care less really.

    Please post links to the the thread you are speaking of out of curiosity....

    Thanks!

    Thanks! I read thru that and unless I'm mistaken, the 640 supports all of those frequencies so I still don't understand why it wouldn't work.

    The 640 variant I bought was an RM-1113 (I have no clue which demographic this variant is) which specifically supports:

    2G bands GSM 850 / 900 / 1800 / 1900
    3G bands HSDPA 850 / 900 / 1900 / 2100
    4G bands LTE 1 (2100), 17 (700), 2 (1900), 20 (800), 3 (1800),
    4 (1700/2100), 5 (850), 7 (2,600), 8 (900), 28 (700),
    12 (700)

    So I still think I'm covered unless I'm drunk haha!

    I have the same one from expansys. You should be fine I'm using it on Cricket. Works well. Tried a speed test and got 10 mb dload. Popped in a pay as you go tmobile sim and got 21 mb dload.

    I can't believe the battery on this thing. Up to 3 days now on a single charge. I don't use my phone much but thats still damn impressive.

    Hmmm? Cricket's proxy servers limit maximum LTE speeds to 8mbps download and 4mbps download on HSPA+. They state that in the terms of service. If you got 10 mbps it was probably a short-lived thing.

    Apparently the T-Mobile Lumia 640 has been spotted on sale at some Wal Marts for around $99.95! Apparently that version would be usable on any T-Mobile MVNO as well as T-Mobile prepaid. Not sure if it also has wifi calling capability built in.

    Glad to see this phone start to hit the US. This is likely my upgrade for my Lumia 635, looking forward to ATT to get this phone.

    The 640 LTE dual sim works just fine as a 4G phone (but pops up as LTE on rare occasion) on AT&T and T-mobile today. (since its already unlocked) The AT&T manager I talked to said they expect fully functional LTE on all 640s before July. The 640 LTE dual sim works with AT&T band 7 out of the box, but, only at 4G in certain areas.

    The 640 LTE on T-mobile is reportedly able to be flashed to the international (india?) firmware, but, I don't know this for certain as I just use mine as is right now.

    That would mean faster updates correct?

    FedEx delivers the phone tomorrow and my sim adapter just arrived today. I will be testing it with an AT&T and Digicel sim card. Will report back.

    EDIT: Keep in mind too that I'm PST and will need time to unbox and play with it/test before reporting the results.
