T-Mobile & wi-fi calling on dev edition - One (M8) Q&A, Help & Troubleshooting

Dev edition vs T-Mobile version, are these hardware differences, or software? Could I flash a T-Mobile radio onto a developer edition to unlock the bands to get HSPA+ on PCS(1700 and 2100)?
Also T-Mobile plans on rolling out 700MHz LTE later this year, would this be compatible?
The developer edition is an "AT&T variant" which restricts some bands, meaning I drop down to EDGE in some areas where T-Mobile hasn't refarmed(modernized) their spectrum.
from anandtech:
>As far as I can tell only the AT&T and Google Play Edition SKUs support carrier aggregation. The two SKUs are quite similar from a cellular standpoint, with the AT&T model locking out UMTS band 4 to discourage movement to T-Mobile.
also, could I get wi-fi calling if I found and flashed a T-Mobile stock rom?

CDMA 3G in Europe?
This arcticle mentions this is a CDMA 3G /umts data capable, but isn't this a US - only service that will not function in Europe?
T-mobile is still a German company, i think they will sell it in Germany as well. Maybe there will be different versions?!
My understanding, based on a thread over at Howard Forums, is that this is a tri-band phone (i.e. no 850 MHz) and will NOT be offered in the USA. Cingular (the biggest GSM provider in the US) is moving to 850 MHz, so this device may not work on their network.
This device will work in the USA with T-Mobile as the service provider.
Cingular own 850 and 1900 spectrum however I've read on HoFo that the 850 band is becoming the control band (i.e. you need this to register on the network). I have tried my cingular SIM in my SE P800 and it doesn't connect to the network.

Tmo is 1700/2100 and ATT is 850/1900 right? So does this mean the TMo version can do 3g on both networks? I wonder if the ATT version will work the same way?

I thought I had that down, but there's skepticism, and I'm not that knowledgeable when it comes to carrier bands, so when Epsilon posted, I decided to poll the forum.

I'm pretty sure the 850/1900MHz frequencies listed on those specs are part of the GSM bands it will cover, as it has Quad-band GSM, and not part of the 3G frequencies it will use.

So my question is, does the part of the spec sheet I posted above mean the TMo version could be, once unlocked, used on ATT's network with full 3G?

LTE on Bell Canada?

Hi guys,
I got 2 days ago an LTE SIM card and I'm trying to setup the option "LTE/GSM auto" in my GT-I9250, without success.
This is how my settings look:

I got the phone from Google Store. When I select the option from drop-down menu, it pushes it back to "WCDMA preferred". I called the tech support and they told me that the LTE option is enabled on my phone account. What am I missing? Bell offers LTE AWS (1700 MHz) and LTE (700 MHz), does the Nexus have support for these bands? If any of Bell users managed to switch their Nexus to LTE, please let me know what you did.
Thanks for your help.
The gsm nexus doesn't have an lte chip. as far as I know lte won't work with that phone.

[Q] Verizon Galaxy S3 with T-Mobile SIM card, Data only "E"???? Why??

I have Verizon wireless galaxy s3 and it is completely flashed with "Omni" ROM. Today, I switched from Verizon service to T-mobile service. It is working with Calls, But data always in "E" edge network. How can I get LTE or 4G network on Verizon galaxy s3 with T-Mobile SIM card?
I think I have right APN settings?

Probably not possible. If im not mistaken, T-Mobile uses different bands than Verizon and each carriers device is made to use their frequencies.
You can't for the reason doc said.. The apn you want is the LTE one, try the other T-Mobile apns but I doubt it will pick up..
Just as others have stated, it is because the phone does not support the freqencies that T-mobile uses. I have read in a few forums where people have reported better than Edge in certain areas where T-Mobile has refarmed. I too had a SCH-i535 on the T-Mo network for awhile, so I know your pain. That is why I sold my SCH-I535 in favor of the T999L.

Question 5G bands with AT&T prepaid

AT&T told me that I have to upgrade my prepaid plan in order to get 5G speeds (I know, they're not really 5G), and I don't want to keep $1100 phone and pay more for service if I am unable to get them because phone does not have correct bands. Three websites list different bands for US model and I could swear OnePlus website did not list bands n260 and n261 a week ago. Then who is finally right?

Or finally OnePlus?
If you buy the North American variant, the bands are there.
But the problem with AT&T is that OnePlus has not certified
the 9 series for their 5G network so you wanna double check that
but regardless you have to buy the correct model for North America(U.S & Canada).
