    And that, specifically, Band 4 flavor 1700.
    UMTS frequency bands - Wikipedia, the free encyclopedia


    Why are you confusing Band 4 LTE with AWS 3G/HSPA? AT&T 1520 variants support Band 4 LTE (1700MHz), everyone knows that. It does not support AWS band (1700MHz/2100MHz) which is what T-Mobile's legacy (non-refarmed markets) 3G/HSPA network works on. So does Rogers Canada, Wind Canada, Bell Canada, and the so called 1520.3 LTA model.

    Having an option enabled in Field Test doesn't really mean the hardware supports it. On the other hand, not having an option in field test doesn't mean the phone doesn't support that frequency. For e.g. my pentaband 920 only lists 2 options under 3G, All Bands and UMTS Band 2.

    Did you not look at the tables I linked? AWS 1700/2100 is 3G Band 4. Exactly the same on T-Mo in legacy areas and on Wind in Canada.

    I'm not confusing the two at all.

    In that case so is the 810 LTE capable :D


    Unless I see the UARFCN bands, I am not convinced. There is a 300 Pg thread claiming folks have enabled AWS on the AT&T 920, eventually no one did.

    A UARFCN screenshot on T-Mobile/Wind CA/Rogers CA's 3G network on an unlocked RM-940 would be the only proof. That takes like 2 mins to post

    Well I've neither an RM-940 or a SIM from T-Mo, Rogers or Wind. I just believe users like the ones who report it as working in areas that require that 3G Band... One of them will have to supply the screenshot you are asking for.

    Well that's what I tend not to do unless there's enough proof. This might help save someone's wrong purchase

    I'm not sure why screen shots dont work in the field test menu, but I took a picture of the phone's screen. You can see that I'm getting a 4G HSPA connection (not LTE, since WIND doesn't have the spectrum) in the top right.

    There's your proof then. UARCFN 1987 is AWS, specifically Band 4 portion of it. I had tested it in the past but didn't have screen shots on me

    Okay this is promising. Now some using it on T-Mobile might be able to confirm?

    Thanks. Looks like I am getting UARFCN readings of 462 and 2062, which appears to be the PCS 1900 and 1700 bands, respectively. Guess that proves it works
    Just for good measure, I confirmed the use of band 4 umts in December. Helps if you read the whole thread

    This was seen running on T-Mobile. I am back using AT&T so I can't test again unfortunately

    H+ in North America is referred to as 4G even though it isn't. LTE is denoted with LTE. The picture above is showing connection to the HSPA+ network

    Yes. Thank You N/A Carriers. They think their customers should be treated like mushrooms. Kept in the dark and fed... composted animal waste.

    After reading the spec sheet was confused when confronted with this quirk in marketing.
    Corps have no qualms or restraints regarding specs. Regulatory capture at it's finest.

    True enough... The carriers control the decision on what label to apply and the hardware must interpret it as best it can. That's the root cause of the term "faux G." Carrier marketing hype that H+ (3.5G) get labeled 4G until they could roll out LTE.

    "Difference between RM-938 and RM-940 is that DTM feature and WCDM1700/2100 (Band 4) will be disabled from RM-940, and RM-940 will GPRS support multi-slot class 10."

    This means WCDM1700/2100 (Band 4) is hardware disabled? the tweak from picture in step 5 is will not enabled WCDM1700/2100 (Band 4) ?

    It works, people (including myself and the above poster on Wind in Canada) have used it. End of discussion

    Ha, new to me.
    With the specs and hardware not matching it's tough.
    From what I read:
    4G standard is > LTE > H+ > H....and so on.
    In reality:
    4G denotes H+ < LTE
    Since industry wrote the specs one would think they would follow them.
    By law? But that is another story.
    Broadband anyone.

    Not to confuse you even further, but technically LTE isn't even 4G, its 3.5G similar to HSPA+. The first true 4G is LTE-Advanced, but the consortiums finally all got together and reclassified it as 4G

    From an earlier post
    From Wikipedia:
    Although marketed as a 4G wireless service, LTE (as specified in the 3GPP Release 8 and 9 document series) does not satisfy the technical requirements the 3GPP consortium has adopted for its new standard generation, and which were originally set forth by the ITU-R organization in its IMT-Advanced specification. However, due to marketing pressures and the significant advancements that WiMAX, HSPA+ and LTE bring to the original 3G technologies, ITU later decided that LTE together with the aforementioned technologies can be called 4G technologies. The LTE Advanced standard formally satisfies the ITU-R requirements to be considered IMT-Advanced. To differentiate LTE Advanced and WiMAX-Advanced from current 4G technologies, ITU has defined them as "True 4G".
    From ITU:
    Following a detailed evaluation against stringent technical and operational criteria, ITU has determined that LTE-Advanced and WirelessMAN-Advanced should be accorded the official designation of IMT-Advanced. As the most advanced technologies currently defined for global wireless mobile broadband communications, IMT-Advanced is considered as 4G, although it is recognized that this term, while undefined, may also be applied to the forerunners of these technologies, LTE and WiMax, and to other evolved 3G technologies providing a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed. The detailed specifications of the IMT-Advanced technologies will be provided in a new ITU-R Recommendation expected in early 2012.

    I think this thread is showing pretty conclusively that it is software disabled, but not irreversible. It's onboard, just masked from casual users.

    Well I have ported my line to T-Mobile and have enabled these settings on my phone. I am not sure yet how to confirm whether or not it is working but did look briefly into the UAFCRN numbers and there aren't a lot of resources out there in what they map to. So far no negative feedback though.
