How To: AT&T Lumia 1520 (RM-940) on T-Mobile/Wind/Mobilicity AWS1700Mhz/HSPA+ Band 4

Re: Instructions: AT&T Lumia 1520 on T-Mobile AWS 3G (HSPA Band 4 - 1700)

I guess a screenshot of H+ on the top would prove everything.

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.

Whatever you want to believe. That's the default, but carriers are free to customize it

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.

Any other features disabled on rm-940 compare to rm-938 ? frm radio, camera features, 4k recording.... ?

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

I'm waiting on the unlock code to try this with my T-Mobile SIM, very interested in this....

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.

You can find UAFCRN numbers on these tables for UMTS Frequencies/Bands: UMTS frequency bands - Wikipedia, the free encyclopedia

If this works, that will be awesome.

I don't use Qi so might prefer an AT&T over my 1520.3. Basically then its a trade off between 32GB and having a US warranty Since I put all files on SD and just apps on the phone, I think 16GB might be enough. And if not, isn't there a 32 GB AT&T 1520?

its only in black and only on line from att or amzon

You can also put apps on the SD card without any problems

Incredible hack and news! Thanks OP!

Can anyone confirm this still works after Denim update? About to get an ATT version for AWS 3G (Wind) use but worry they patched the hack. Thanks guys!

So I am new to the forums, I have been looking for awhile for a good windows phone with all the features I was able to track down a 1520.3 for $399 used, or I can get a used At&t 1520 in mint condition for $329. Do we feel confident the settings work, or should I be safe and go with a 1520.3?
